What are the saws for woodworking

Chain saws

Often, when working with wood, it is not the cleanliness and accuracy of the cut that is important, but its depth. This is exactly the task that a chain saw solves. a powerful device with an electric or gasoline engine, designed for felling and cutting firewood.

It has two main interrelated technical parameters:

  • Engine power;
  • Bus length.

A bar is called two flat plates connected to each other with a small gap for installing a saw chain. At one end it has a driven sprocket, and on the other there are cutouts for the tensioner.

saws, woodworking

The power of the electric chain saws ranges from 1.5 to 4 kW. When choosing a device for household work on the site, it is better to stop at a power of 1.5 to 2 kW with a saw bar length of 30 to 40 cm.This is quite enough not only for sanitary pruning of the garden, but also for harvesting firewood.

If necessary, you can dissolve a board, log or bar with such a tool, although you will not get high quality and cutting accuracy.

There are two types of chain saws:

  • With lateral (transverse) engine placement;
  • With longitudinal motor installation.

The first type is simpler in design and cheaper in price. But the second is more convenient to use, although more expensive due to the introduction of a gearbox into the design.

The main thing that gives the owner a chain chainsaw is autonomy. With such a tool, you can go into the forest and cut firewood there. For such a significant plus, you will have to pay a price: chainsaws are more complex in design than electric ones. This difference is especially felt when buying a cheap “but-hiring” device. Problems with starting, carburetor, rings and spark plugs are frequent companions of such a purchase. Therefore, it is better to purchase a more expensive chainsaw than to lose money when operating an economy option.

What are the saws: the main types and characteristics of the tool

The household also cannot do without saws. Every man has at least one hacksaw, and a good master has a whole arsenal of “toothy helpers”.

We will look at the most common types of saws to get an idea of ​​their working capabilities and application features.

Circular saws

The idea of ​​replacing the back-and-forth motion of the cutting blade with a circular one can rightfully be called revolutionary. It arose after the advent of the electric motor and significantly increased the speed and productivity of work.

A typical representative of a tool that uses this principle is a circular saw. Its main advantages. mobility and high power overshadowed the modest capabilities of a hand hacksaw.

By design, circular electric saws are divided into geared and gearless. In the first case, an electric motor rotates a gear reducer, on the shaft of which there is a saw blade. The second option is to mount the disc directly on the rotor shaft of the electric motor. Both designs have a mechanism for adjusting the cutting depth and tilt angle.

The advantage of gear mechanisms is the ability to cut deeper. Gearless saws have two advantages: less weight and an affordable price.

The second category of differences is in the features of the saw blade. He can be active or passive. Everything here is determined by the shape of the tooth. The active disc has bent teeth in the direction of rotation.

In the passive, they are inclined against the course (negative sharpening angle).

Passive discs are indispensable when cutting metal. Active ones are used for wood processing. The teeth of the disc can be tipped with carbide. They make it possible to cut harder materials, but negatively affect the cleanliness of the cut.

The working capabilities of the tool depend on the power of the electric motor (from 0.65 to 2.5 kW). Manufacturers also indicate the maximum depth of cut that can be performed with a circular saw (25 to 85 mm).

A variation of this power tool is a circular saw, which is mounted on a fixed bed. This solution allows you to cut long and wide material with high precision.

Some manufacturers offer an interesting compromise. hand-held circular saws that can be turned over and fixed on the table, turning into a stationary “circular”.

Answering the question, what kind of saws are, one cannot fail to mention the miter devices. In this case, the saw blade is mounted on a pendulum arm. A rotary plate with protractor (corner) markings is used as a bed.

The advantages of a miter saw over a circular saw are obvious: you can make a perfectly accurate cross-cut at any angle. This operation is especially important when joining various wooden parts (platband, plinth, lining, timber).

It all started with a simple hacksaw

It is this saw that is the ancestor of the family of hand tools designed for woodworking. As soon as the first iron ingot was smelted, a man had the idea to forge a tool for cultivating the land from it.

It can be assumed that the ax became the second after the hoe. The third was probably a saw with a handle, known to us today as a hacksaw. Over the centuries that have passed since its invention, she has acquired numerous “brothers and sisters”, performing dozens of different jobs.

The accepted classification divides this type of hand saws into two groups:

  • Hacksaws for wood;
  • Hacksaws for metal.

Depending on the direction of cutting, hand saws for wood are divided into three categories:

  • For rip sawing cutting;
  • For cross cutting;
  • Universal (longitudinal-transverse).

The difference between them lies in the shape of the cutting teeth: they are inclined forward on the rip saw, and straight lines on the cross hacksaw.

The universal hacksaw tooth is also tilted forward, but has a special sharpening. It allows you to cut along and across the grain.

By design, hand saws are divided into several types:

  • Classic hacksaws (transverse or longitudinal cutting);
  • Circular saws (for cutting holes);
  • Spike saws (for cutting connecting spikes).

When choosing a hand hacksaw, not only the shape, but the size of the teeth plays an important role.

There are three types of incisors:

  • Fine tooth. 2.0-2.5 mm (for high-precision sawing and cutting of small items);
  • Medium tooth. 3.0-3.5 mm (for medium-sized parts);
  • Coarse tooth. 4.0-6.0 mm (for coarse cutting of cant and logs).

The international classification divides hacksaws not by the height of the teeth, but by their number per 1 inch of the cutting blade. This standard has taken root in our country, so do not be surprised if you see the letters PPI or TPI on the instrument label. The number behind them is the number of teeth per inch of length. The larger it is, the smaller the tooth (e.g. PPI 8 or TPI 14).

Today on the market you can see a modernized type of hacksaws. They can be easily distinguished by the gaps cut in the canvas. As a result, the teeth are arranged in groups of 6-7 pieces.

This tool is designed for cutting raw wood. The gaps between the teeth are needed so that wet chips do not clog the cut and are easily removed during work.

In addition to the usual hand hacksaws, users are now offered an electrified version of the tool. The powerful electric hawser can easily handle a large amount of sawn timber cutting without too fatiguing the owner.

Its versatility is achieved by being equipped with saws with different lengths and widths of the blade and the size of the teeth. This allows you to successfully work not only in wood, but also in plastic and metal. Another name for this tool is reciprocating saw.

The main parameter characterizing the capabilities of electric hackers is power. It ranges from 400 to 1600 watts. The cutting depth directly depends on it, which ranges from 90 mm for household models, up to 200 mm for professional models.

Hand tools for metal processing are not so diverse. There is only one type of hand saw that can cut this material. Its working body is a wide or narrow blade with fine hardened teeth. It is inserted into the bow holder and tightened with a screw.

Jigsaw

Circular and chain saws cannot replace a device that uses a narrow blade that moves up and down at a high frequency.

Thanks to this arrangement of the working body, the jigsaw allows you to quickly and accurately cut curved flat parts. Plywood, ceramics and plastic, OSB and soft metal. all this can be cut with a good jigsaw with a quality file.

For each material, manufacturers make special saws, which differ both in the inclination of the teeth and in their frequency.

For example, wood is better cut by a file with a large tooth. With sheet metal, a blade with a fine serrated notch will confidently cope. We will not give special recommendations on the choice of saws for a jigsaw, since the manufacturer indicates the recommended type of material on each of them.

The main technical parameters of the jigsaw are engine power, saw stroke frequency and maximum cutting depth (indicated for different materials).

For household models, these parameters are within the following limits:

  • Power from 400 to 900 watts.;
  • Stroke frequency (with the possibility of smooth adjustment from 0 to 3000 rpm);
  • Cutting depth (wood. 45- 80 mm, steel from 4 to 20 mm).

A useful option for the jigsaw is a laser pointer. It helps to clearly see the direction of the cut when the marking line is hidden under a layer of sawdust. When choosing an electric jigsaw, pay special attention to the attachment in which the file is attached. It should provide the most secure clamp possible. Otherwise, the file will regularly pop out of its weak “embrace”.

Band-saw

The logical development of the jigsaw design has become a compact band saw. Its working body is a closed steel belt with teeth, which is rotated by an electric motor.

Sawing with its help is easier than working with a jigsaw, which vibrates strongly and strives to get out of your hands. The cleanliness and precision of the band saw is ideal. This not only reduces waste, but also produces a cut surface that does not require sanding.

The workpiece can be held here with two hands, which increases the accuracy of operations when cutting curved elements.

The main indicator of band saws for wood is the cutting depth, which can be from 8 to 50 cm.The jigsaw and circular saw are not able to cut such a thick material.

The rest of the specifications apply to cutting blades.

There are two categories here:

  • Carbon saws (made of steel С75 and analogs);
  • Alloy saw blades made of D6A steel (have increased wear resistance and resistance to alternating loads).

Depending on the manufacturing technology and hardening of the cutting teeth, the blades are divided into two types:

  • Saw blades with serrated unhardened teeth;
  • Sliced ​​hardened tooth blades.

The advantages of the saws of the first type are low cost and the ability to cut wood with foreign inclusions: nails, stones, splinters. They work with such a blade at small sawing volumes (2-4 m3 per day) and at a minimum feed speed (6-10 meters per minute).

The main advantage of a saw blade with a hardened tooth is its high wear resistance (2 times higher than that of saws with unhardened cutters). Disadvantages. high cost and sensitivity to foreign inclusions.

The rest of the parameters of the band saws are summarized in a simple list:

  • Web width;
  • Teeth Per Inch Length (TPI).

For standard sawing jobs, a 1/2 ″ band is ideal. Narrower blades (3/8 “) are used for shape cutting.

The number of teeth of the cutting band directly affects the evenness of the cut (the more there are, the smoother the cut). Coarse saw blades (2.3 TPI) are used for cutting wood and logs up to 200 mm thick. For cleaner work, saws with 6 TPI are used, and for precise cutting, the size 10-14 TPI is used. Optimum size for high productivity and good cut quality. 8 TPI.

The metal table saw is similar in design to a wood cutter. However, its capabilities are more modest. This tool can only perform transverse cutting of rolled steel (pipes, angle bars, fittings, channel bars) at different angles.

By type of cut and purpose

Hacksaws can be designed for cross-cutting, longitudinal (swinging) or be universal. Between themselves, these types differ in the shape of the teeth.

The teeth of saws intended for longitudinal cutting of wood have the form of an oblique triangle. The angle between them is from 45 to 60 °, which allows you to cut wood in only one direction, while maintaining an accurate and straight cut line. Most often they are used in the manufacture of furniture.

Hacksaws with teeth resembling an isosceles triangle are used to cross-cut wood. Sharpening at an angle of 45-55 ° makes it possible to cut workpieces both in the forward and reverse direction. This saw works most effectively on dry wood.

The universal hacksaw has two types of teeth. triangular and semicircular (while semicircular more than triangular). When the saw moves forward, the long teeth set the direction, and the wider, triangular teeth widen the cut, which allows sawdust and shavings to exit freely. The smaller the angle between these teeth, the more accurate the cut is.

Depending on the purpose, hacksaws for wood are classic, circular and spike. Classic saws are used for longitudinal or cross-cutting of wood. Circular hacksaws for wood are designed for cutting holes. With the help of tenon saws, elements are formed for connecting individual parts.

  • 40 cm saw blade with plastic handle designed for cross-cutting wood.
  • Small size hardened teeth (11 pcs per inch length) are highly resistant to workloads.

The main characteristics of the electric hacker

The electric chopper is used in confined spaces where it is not possible to use a circular or chain saw.

Which Hand Saws Do You Need For Traditional Woodworking?

The power of the household appliance is 1.3 kW, professional. 1.3-1.8 kW. The design has an electric motor block, a guide and a cutting part that moves along the guide. The length of the canvas can reach 40 cm.

If we compare the quality of sawing, then with the help of an electric chopper, a cleaner cut is obtained. And in comparison with a circular saw, the electric hacker has no barriers in cutting depth. But there are also obvious disadvantages. Even a professional electric chewer is not suitable for basic firewood harvesting, since the working element wears out quickly and productivity drops sharply.

Types of electric saws for wood and features of choice

Hand saws are gradually becoming a relic of the past, giving way to power tools, which significantly increase the quality and speed of work. Today there are several types of electric saws that differ from each other in their design and purpose. Let’s tell you more about them.

Tooth size and shape

The size of the teeth (pitch) of the hacksaw blade directly affects the productivity and accuracy of the tool. The larger the teeth, the higher the working speed, but the accuracy and quality of the cut deteriorates. On the other hand, using a fine-toothed saw guarantees a clean and even cut, but the speed is reduced.

Cutting accuracy is determined by the number of teeth per inch of blade length (TPI coefficient), that is, their density. Its value is marked on the side surface of the web (for example, 7×1 ″ or 7TPI). The higher the TPI, the smaller the step. So, 2TPI = 12 mm, and 12TPI = 2 mm.

When choosing a hacksaw for wood, it must be borne in mind that the minimum thickness of the workpiece must be greater than the pitch of three teeth.

When working with a hacksaw on wood, the appearance of sharpened teeth is essential. In this case, teeth are considered standard, sharpened on both sides and having the form of an acute-angled or isosceles triangle.

Important! The latest generation of saws is equipped with non-standard hardened teeth. They have the appearance of a trapezoid and are distinguished by the presence of three sharpened edges and increased wear resistance. Blades with such teeth cannot be re-sharpened.

The best saw blades with a diameter of 216-260 mm

The accessories for circular saws with a diameter of 216-260 mm are used for sawing boards, panels and large cross-section bars. The maximum workpiece thickness should be slightly less than the disc radius (105-120 mm). But if the cut edge is further processed or veneered, then it is allowed to cut through the wooden element from both sides, combining the two cuts, which doubles the maximum thickness indicator. TOP saw blades for wood for circular saws will show which equipment to choose for cutting wood of different moisture content and type of cut.

CMT 292.216.64M (216x30x2.8 / 1.8 mm; Z64). specially for cross cut

Cross-cutting wood is not easy for every blade. The reason lies in the perpendicular arrangement of the fibers, which creates increased resistance. To understand which saw blade for wood is better in this case, you need to remember that it must have alternately beveled teeth. This provides a soft impact and allows you to cut without severe scoring and chips.

  • If used on hard wood, it may burn the butt a little.

Output. An excellent choice for making a large volume of cross cuts, which then do not have to be processed additionally. all ends can be made to size the first time.

How to choose a power saw

When choosing a household power tool for occasional use, the main selection criterion is an acceptable price with sufficient power, versatility of use.

So, when choosing a saber electric shovel, you do not need a large set of functions. Enough speed controller with two positions, telescopic support, articulated stop.

Experienced users prefer the choice of ergonomic models, with rubberized handles, comfortable power buttons.

Replaceable blades allow you to use the electric hanger to work with wood of any hardness, cut thin metal, ceramic tiles.

For carpentry, handicraft work in a home workshop, the main tools are a stationary disk (circular) electric saw and a jigsaw.

These devices, supplemented with hand tools, will allow you to perform production operations for the manufacture of windows, doors, homemade home furniture.

A household electric saw with a rechargeable power source is convenient for garden work.

Experienced users, noting the convenience of using battery power saws, consider their disadvantages high cost, short-term operation, low charging speed.

A household gasoline saw is superior in power to electric saber-cutters, and allows for more than just branching.

DIYers use medium power chainsaws in a variety of carpentry jobs.

With sufficient skill, using a chainsaw, you can build a log house or a bath from a solid, rounded log, bar.

Household saws for woodworking

In a set of professional tools for joiners, carpenters, cabinetmakers, there are dozens of types, hacksaws, bow saws, jigsaws, various in size, methods of application.

For home, country, garden, farm work, large tools are not needed.

Saws for wood have their own design features and differ from other types of saws, for example, designed for working with metal.

The saw for wood has a special design of teeth and is made from certain grades of steel.

When choosing a saw, home craftsmen who do not have a technical education should understand what the effectiveness of the sawing tool depends on, and be able to choose it for a certain type of work.

Classification and application of hand tools

Hand saw. luchkovka

In the most general form, hand saws are divided into bow (stretched) structures and hacksaws.

In the bow design, the tension of the blade is achieved by moving the movable cheeks of the machine, equipped with ears for fastening.

The classic hacksaw does not have a tensioning mechanism. The strength and weight of the blade attached to the handle is sufficient for normal operation.

Hand saw. hacksaw

A type of large hacksaw has become a two-handed saw, which is pulled by physical effort when broaching.

A compromise between the two designs was a tension hacksaw on a metal machine and a jigsaw of the same design.

In such saws, the blade is pulled with special wing nuts.

The main differences that determine the use of a saw depend on the length of the cutting blade, the size and shape of the teeth, their setting.

Hacksaws for cross-cutting wooden beams, boards are equipped with triangular teeth.

Loppers, saws for cutting shrub and tree trunks are equipped with the same blade.

Hand Saw. Lopper

For longitudinal sawing of a tree (along fiber lines), blades with oblique (oblique) teeth are used.

Cutting speed, applied force, cutting thickness depend on the height of the teeth, their shape, frequency, sharpening and setting of the cutting edge.

An undiluted saw on wood is clogged with sawdust, an incorrectly sharpened edge of the teeth requires extra effort when cutting.

Various degrees of tension of the bow saw blade are used for straight, oblique, curly cuts. The tighter the web is stretched, the harder it is to turn.

Straight cutting requires the use of a wide hacksaw blade; for figured cutting, narrow blades with fine teeth are used.

The smallest and most frequent teeth are jigsaw blades, which produce fine artistic cuts on soft wood or plywood.

When working with soft wood, high teeth are sharpened at 40. 50 °, for hard woods, fine teeth require sharpening at an angle of 70 °.

Hand Saw. Interchangeable Blade Jigsaw

Jigsaw blades do not sharpen, they are easier to replace.

Hacksaws, loppers, in the blade of which the teeth are grouped in 7-8 pieces and separated by a deep cut, are intended for wet (live) wood.

For home use, gardening, universal hacksaws with a single handle and replaceable blades (with various blade and tooth configurations) are convenient.

Special hacksaws with a backing, veneer saws, beads, circular saws, spike hacksaws are rarely used in household work.

Electric and gasoline saws

Chainsaw with saw chain

Different Types of Hand Saws and Their Uses

A mechanized tool for operations with wood allows you to speed up all household, household work, to perform them with less effort, more accuracy.

Power saws for wood are divided according to power sources (into electric saws and chainsaws) and the shape of the cutting surface (disc, straight blade, tape, chain).

For works remote from the power supply, a chain chainsaw is in demand.

In household work, chainsaws are most often used for felling trees, preparing firewood, in country or suburban construction.

Chainsaw selection criteria depend on the area of ​​use, engine power, bar length (saw chain).

Household or semi-professional chainsaws are used for household work; it makes no sense to buy an expensive professional tool for felling wood (with high power, cutting speed).

In household use, a farmer, summer resident has a fairly inexpensive chainsaw (with a capacity of up to 2 kW, a thirty-centimeter tire) of domestic production.

Such models are produced by the brands “Taiga”, “Zubr”, “Zenith”, “Caliber”.

Electric saw with a saw chain

In turn, electric saws are usually classified by size, mobile or stationary use. Trade classifications are distinguished:
chain saws;
circular saws (circular saws, grinders);
jigsaws;
saber hacksaws;
band saws.

Each type of electric power tool is designed for a specific type of work, it differs in power, thickness and direction of cut, portability, autonomous operation.

The best manufacturers of household, semi-professional tools include the brands Stihl (Austria), Makita (Japan), Bosch (Germany).

Hand Saw Selection Criteria

Hand tools are chosen according to the frequency of use, the specifics of the work, the quality of the canvas, the reputation of the manufacturer.

For periodic use in household work (for minor repairs of windows, doors, furniture), a medium-width universal hacksaw with a trapezoidal tapering blade is sufficient.

Such a tool works well with conifers, suitable for longitudinal and cross-cutting of MDF, chipboard, plywood, drywall.

Cloth longer than 30-35 centimeters for housework is not required.

Several hacksaws with different (in length, width, tooth configuration) blades, a bow saw, a jigsaw will be required for the independent manufacture of home furniture, in construction work.

With an increase in the complexity of operations, it may also be necessary to use finger, circular, veneer saws.

A two-handed saw is most often used when cutting logs for firewood, in construction work.

For garden work, buy special saws for wood with a rounded (sickle) blade, which are sold under the name “loppers”.

This shape of the blade (on a short or long handle) is convenient for pulling the saw from below, increases the tractive effort when working from the ground.

Foldable tool that looks like a large knife, handy for forestry, hiking, fishing, but not durable.

For field work, hand chain saws are more convenient, with which you can saw alone or together.

All blades are made of alloyed tool steel, but of different quality.

Cutting tool manufacturers supply blades with long markings that indicate steel grades (HCS, HM / CT, BIM, HSS), company indexes, text labels about the materials being processed.

For domestic use, it is enough to remember the HCS steel grade (for wood), the WOOD designation (for soft rocks, joinery boards).

In color markings (painting of blades), foreign manufacturers for wood saws most often use gray.

Choosing a universal hacksaw for occasional use, it is not necessary to understand complex blade markings.

A simple test is to try to bend a hacksaw. Perfectly straight tool made of high quality steel.

Operating rules and safety precautions when working with power tools

The hand saw for wood does not require special storage and maintenance measures. It is enough to store it in a dry place, in a special box.

With occasional use, the canvas is protected from rust by lubricating with grease.

To avoid injury, it is better to work with hand tools in canvas gloves.

Self-sharpening of teeth can only be recommended for experienced users.

Black color of the cutting edge is used for hardened or ceramic teeth. Such wood saws are sharp and durable, but cannot be sharpened.

complicated rules for operating a power tool.

The chainsaw must be run in, lubricated regularly, and all requirements of the manufacturer’s instructions must be followed.

Drainage of fuel after work is mandatory, occasional sharpening of the saw chain, which is better to entrust to specialists.

The same requirements apply to the mechanical part of electric saws.

When operating the electric saw, you need to constantly monitor the condition of the cable insulation, the contacts of the electric motor, the integrity of the plug.

Safety rules when working with power tools prohibit their use in case of fatigue, while intoxicated.

Do not work without a protective cover, carry the tool to another place with the.

Inexperienced users are not recommended to work with a power tool above shoulder level, from uncomfortable (unstable) positions.

When working for a long time, it is imperative to wear safety glasses, special earplugs or headphones, gloves.

When pruning, cutting garden trees, a protective helmet will not interfere.
