Which Bits Are Best For A Screwdriver

Screwdriver bits

Bits for a screwdriver are almost always necessary for repair and construction.

It is difficult to imagine repair work without screwing in screws, screws and other similar parts.

When the number of fasteners is large, a special electric tool is used, but its functionality largely depends on whether the bits for the screwdriver are correctly selected.

Bit adapter

Bit adapters are used to simplify construction work.

They are equipped with special magnetic holders, there are models with an internal fixation in the form of two curved legs.

This adapter allows you to use standard attachments and NOT purchase a kit every time you change the screwdriver.

Fork bits

She is a subspecies of anti-vandal slot.

Only high-quality steel is used for manufacturing, which allows it to be durable and serve for a long time.

Outwardly, it resembles a flat slotted bit, which has a slot in the middle.

May be with increased length and have increased strength.

Tri-wing slotted bits. three-blade

The tri-wing bit is three-bladed, with the blades angled (as opposed to ribs in a cruciform nozzle).

Used in the assembly of household appliances and electronics.

Drywall Bits

Bit for drywall with limiters is used when working only with gypsum board.

This is due to the fact that when fastening the sheets, you cannot press hard on the self-tapping screw, and as soon as the limiter reaches the surface of the material, you must definitely stop working.

If this is not done, then the slots from the screw head will be cut.

This can cause the drywall bit to wear out and clog the notches with metal filings.

Bit classification by material and coating

Screwdriver bits are made from various metals, both soft and hard.

The quality of products and their service life primarily depends on the material from which they are made.

The following alloys are considered the highest quality:

Molybdenum and Chromium;
vanadium and chromium;
molybdenum and vanadium;
silicon-fired sinter.

Steel options are also on sale, but they are expensive, and they quickly wear out during operation.

Even the presence of victorious soldering is incapable of extending the service life of steel bits.

They can also crumble when colliding with a hard rock of a mineral nature.

Titanium coating can increase the strength of steel tips.

Less reliable is diamond, nickel, and tungsten-nickel alloy plating.

Tungsten is responsible for high strength, and nickel protects the product from corrosion.

With anti-vandal slots

The bat with anti-vandal slots is called by the master “snake eye”, since K. It has a socket for a fork wrench.

Screwdriver bits

Bits differ in size, shape, material and the presence of a protective coating.

They represent an oblong metal hexagon, which has two sides.

One side is working, and is intended for screwing in hardware, the other side of the bit is inserted into the screwdriver.

Flat. for tightening screws and screws;
hex. for furniture production;
for bolts. intended for fastening tiles or corrugated board;
for drywall, which have a built-in limiter;
triangular, etc.

Also bits are divided into:

The main
They have a working element in the form of a cross, provide reliable fixation with screw heads.

Bits can be used in any field of activity.

Combined

They are characterized by a double working part, while each of them may differ in size and appearance.

During work, it is fixed in the chuck of the screwdriver with an unnecessary half, and the work is performed with the rest.

Special

Are highly specialized products.

Special bits are rarely used in work, so they are sold only by the piece.

How to evaluate the quality of bits for a screwdriver

So that in the process of work there are no difficulties in the choice of consumables, you should approach responsibly.

Therefore, it is recommended to know in advance how to evaluate the quality of the bits before purchasing.

How to choose bits for a screwdriver

To make it easy and convenient to work with a screwdriver, you just need to choose the right bits.

At the same time, it is desirable to choose high quality products, even if their cost may be a little overpriced.

Before buying, you should study the recommendations for choosing bits from specialists.

Which bits are better for a screwdriver: types, sizes and their designations

Today, in any household, an electric type screwdriver will become indispensable. With its help, you can assemble furniture, make repairs or make something several times faster. The beat plays a huge role in the operation of the instrument. At first glance, this part of the tool may seem quite insignificant, but in fact, it depends on it how convenient it will be to tighten screws or all kinds of screws.

If you choose the wrong bit for your screwdriver, this will lead to the fact that it will always jump off the head or rotate directly during operation. As a result, the bit tip will be broken or damaged prematurely. To prevent this from happening, you need to know which bits for a screwdriver are best suited.

Overview of bits for a screwdriver varieties and designations

Today, experts distinguish several different forms of bits for screwdrivers, namely:

• Combined;
• Special;
• The main.

In most cases, cruciform bits of the basic type are used in construction. They have several standards: PH and PZ. PH is an abbreviation for Phillips. Sizes can be from 0 to 4, but bits are most often used. It is worth noting that the bit has an excellent shape, because then the contact area increases several times and this allows you to evenly distribute the load. If you use bits for this type of screwdriver, then the risk that the tool head will be torn off or the slot is damaged is several times less.

PZ is short for Pozidrive. These bits also have a cross-shaped working part. The main difference is that in addition to the presence of the main four ribs of large size, there are four additional ribs. They are located diagonally and are slightly smaller. Thus, the contact area is increased even more. In most cases, a bit for a screwdriver of this type is used to unscrew screws that have become rusty or, for example, jammed in some specific material. Professionals use them without fail if the volume of work is too large. The sizes of such nozzles also range from 0 to 4, but in most cases they also use.

Screwdriver bits, which are better? If it is necessary to repair household appliances, cars, then you cannot do without the use of Special T-bits. They allow you to tighten or, on the contrary, to unscrew the screws, which have a star-shaped surface.

Flat bits are used so that you can work with fasteners, which are used for soft materials. These types of screwdriver bits are effective under heavy loads. If we talk about marking of this type, then SL, from Slot, sizes are from 0 to 7.

If you need to deal with all sorts of bolts or nuts, then you cannot do without a bit, which is made in the form of a wrench. In this situation, it is worth noting the fact that such attachments can only be installed on very powerful screwdrivers. The size of the bit can be different (6-13 mm) and it is best to choose it in accordance with what kind of bolts you will have to work with in the future.

In turn, special bits are used in order to repair machinery or industrial equipment, special fasteners. This means that they are used in Special rather narrow areas. Triangular bits for a screwdriver are considered popular and those that have two small projections in the form of horns. Special bits include those that experts use for convenient work with drywall. In this situation, a certain limiter is installed, which does not allow screwing the self-tapping screw too far, which can lead to damage to the surface.

Which bits are best for a screwdriver? It is also worth considering specialized bits, which have spring clips. In this case, the screws can be tightened at an angle of 30 degrees, which is very often used when working in some certain hard-to-reach places. It is worth mentioning about the combined bits, which differ from the rest in that they have two working surfaces. They can be of different types and even sizes, in most cases the combined bits are slightly longer than usual.

Important points to pay attention to when choosing bits for a screwdriver

In order to work with the screwdriver without inconvenience, the result was excellent, and the tool itself could be used for a long time. you need to choose the right bits for work. If you plan to work with many types of materials, it is best to purchase a special set, which includes the basic types of bits.

The second very important question that needs to be studied before making a purchase is what kind of material the bits for the screwdriver and their working part are made from. To date, only three alloys can be called the most reliable and high quality, which can serve for a long time. It is an alloy of chromium and molybdenum, chromium and vanadium, tungsten and molybdenum. Under no circumstances choose bits that are made of steel. They are erased quickly enough, and there is no guarantee that you will be able to finish the work performed with high quality the first time.

Experts say that the presence of a coating on the bit, which would protect its surface, also plays an important role. If these parts are coated with titanium on top, then there is no doubt about the quality of the bits for the screwdriver. In terms of durability, titanium can only be compared with diamond or nickel. It should be noted that this will also be a tungsten-nickel plating. In this situation, tungsten will make the part as strong as possible, and nickel, in turn, will protect the bit from corrosion.

Which bits for a screwdriver are better. it is definitely quite difficult to make a choice, especially for that person who has never encountered construction work before. In such a situation, it is better to heed the advice of a specialist and pay attention to three fundamental points, which were described a little above.

Sets rating

There is no universal answer to the question of which bits are better, but preference should still be given to proven brands. Cheap products will NOT only not allow you to perform the task at a high quality, but also damage the tool.

Manufacturers and characteristics of the sets:

• Bosch 2607017164. quality material, durability;
• KRAFTOOL 26154-H42. adequate price in relation to product quality;
• HITACHI 754000. multifunctional set of 100 pieces;

• Metabo 626704000. the best tooling quality;
• Milwaukee Shockwave. High Reliability
• Makita B-36170. running bits with manual screwdriver, high quality;

• Bosch X-Pro 2607017037. ease of use;
• Metabo 630454000. increased safety margin of the tooling;

• Ryobi 5132002257. large set in mini-case (40 pcs.);
• Belzer 52H TiN-2 PH-2. medium wear of elements;
• Dewalt PH2 Extreme DT7349. High Durability.

Cross

Many firms produce bits with their own markings, but in a standard form. Philips puts the letters PH on the Cross heads and produces them in 4 sizes: PH0, PH1, PH2 and PH3. The diameter depends on the size of the screw head. The most commonly used PH2 is used in home work. PH3 is used by craftsmen in car repairs, furniture assembly. The bits range in length from 25 to 150 mm. Flexible extensions are designed for fastening work in hard-to-reach places.

Pozidrive cruciform bits are double-shaped. Such a nozzle ensures reliable operation with torsional moments, strong adhesion occurs even when the screw head is turned at a small angle in relation to it. The size range of bits is marked with letters PZ and numbers from 0 to 4. The PZ0 accessory is designed for small screws and screws with a diameter of 1.5 to 2.5 mm. The largest head PZ4 fixes the anchor bolts.

How to choose?

If you buy a product by the piece, it is important to select models with:

• The presence of a protective coating;
• High impact resistance.

When purchasing a set, it is worth Pay attention to several other parameters.

• The material the bits are made of. The better it is, the fewer problems will occur in the work.
• The way the item is processed. There are two types of processing. Milling. The least durable option due to the removal of the surface layer of the material. The stairs are a homogeneous structure. Heat treatment of bits allows them to be used in various modes with increased load.
• Profiling. Designed to ease handling of tough fasteners.

• Micro-roughness. Bits with rough edges, coated with titanium nitride, are used to secure fasteners with a special coating.
• Hardness. The standard value for most attachments is around 58-60 HRC. Bits are divided into soft and hard. Hard bits are fragile, but they are more durable. They are used for low torque fasteners. Soft, on the contrary, are designed for hard mounts.
• Design. Metal equipment should not be used in work where there are chips from the same material. This will complicate the fixing process and lead to wear on the workpiece.

Classification and features of the choice of bits for a screwdriver

For repair work, assembly or disassembly of the retaining elements, power tools are used to facilitate the process of fastening and removing the retainers. Screwdrivers and drills can fail due to an incorrectly selected nozzle, therefore, for confident and high-quality multifaceted work, craftsmen use bits. Let’s take a closer look at the modern types of bits, what they are, and how to use them.

Non-standard forms

Triangular nozzles are marked with the letters TW (Tri wing) and a size range from 0 to 5. The head of such a tool looks like a trihedral with rays. Models are used with Phillips screws. This type of screws is usually used in foreign household appliances to protect against unauthorized opening of the equipment. To fix the drywall, nozzles with stops were created, and not allowing the screw to be tightened deeper than the stop.

Square bits are extremely specialized in nature. Designated with the letter R, the slot consists of four faces and is available in four sizes. Square bits are used in the assembly of large-sized furniture.

Fork Bits Flat splines with a central slot. They are designated by the letters GR and are available in four sizes. Type. standard, extended, length up to 100 mm. The four- and three-bladed bits are labeled TW. These are professional tips used in the aerospace and aviation industries.

Non-standard types are included in regular bit sets, but they are not used in home repairs, so it is advisable to give preference to sets containing standard and cross-shaped nozzles for a nut, screw, screw and other fasteners.

Angle and long screwdriver nozzles are designed for working with fasteners in hard-to-reach places. They are flexible and solid, allow you to screw in and out the screws. Made of durable materials, non-magnetic.

Impact or torsion nozzles are designed to relieve the effect of torque, which occurs when the screw is screwed into the soft layers of the working surface. These attachments can only be used with an impact screwdriver and do NOT require an increased load on the device. Bit marking. color.

Hexagonal

Hex head fastening material is held in place with hexagonal bits. Such screws are used when assembling heavy furniture, repairing large-sized equipment. A special feature of hex fasteners is the slight deformation of the bolt head. This should be taken into account when twisting the clips.

Bits are divided into sizes from 6 to 13 mm. The most common bits in everyday life are 8 mm. It is convenient for them to tighten screws and carry out roofing work. Some bits are specially magnetized with metal hardware. Because of this, magnetic bits are one and a half times more expensive than conventional bits, but at the same time they greatly facilitate and speed up work with fasteners.

Features:

The bit is a rod, which is attached to the chuck of the power tool, and the selected drill is already inserted into it. The working surface of the nozzle is a hexagon. Each bit corresponds to the type of fastener.

Tool accessories consist of:

• Drill;
• Magnetic / regular bit and holder (extension cord).

Bits for a screwdriver must be selected for the size of the fastener head and the characteristics of the nozzle itself. Considering all these criteria, the sets are made up of common nozzles from 2 to 9 mm.

Classification by material and coating

Particular attention should be paid to the material from which the bit is made, its coating. Most of the work is done by the surface of the nozzle, and low-quality materials will lead to rapid tool wear.

Quality Bits Available in various alloys:

• Molybdenum with Vanadium;
• Molybdenum with chromium;
• Will win;
• Vanadium with chromium;
• High speed steel.

The latter material is cheaper and subject to rapid wear and tear, so it is NOT considered when comparing performance.

The soldering of the bit is made of spraying:

• Nickel;
• Titan;
• Wolfram carbide;
• Diamond.

The outer coating is always applied, it provides protection against corrosion, increases wear resistance and improves the strength of the material from which the element is made. Titanium drinks appear in golden hues.

Straight spline

These bits are found in all bit sets, as they are used in almost any job. Bits for a straight slot appeared first, today such nozzles are used in working with screws and screws, the head of which has a straight section.

Equipment for a flat slot is marked S (slot), after which there is a number indicating the slot width, the size range is from 3 to 9 mm. All nibs have a standard thickness of 0.5-1.6 mm and are NOT marked. The tail indicates the material from which the nozzle was made. All elements have increased erosion protection and hardness.

Titanium slotted bits are incredibly durable. Gold plating is swept away with the letters TIN, indicating that the tip is made of titanium nitride. These tips are wider than standard. up to 6.5 mm, and slightly thinner. up to 1.2 mm.

Slotted nozzles are often reversible, in combination with a cruciform tip. This is due to the versatility and frequent demand for the product. The thickness of a flat bit is usually NOT indicated, since it has an internationally accepted standard from 0.5 to 1.6 mm.

Some accessories Available in an elongated version. Due to the length, the possibility of tight contact between the screw and the nozzle is achieved, which improves the quality and accuracy of work.
