How To Choose Bits For A Screwdriver

Bit types

  • Direct
  • Cruciform
  • Hexagonal
  • Star-shaped

Special bits can be classified into the following groups:

  • Triangular
  • With persistent drywall stop
  • Spring-loaded and others

Combined are excellent in that they have different shapes of the working part at both ends. The cost is one level higher than other types.

Several bit standards are also distinguished:

  • Ph (derived from Phillips). cruciform bits, which have a conditional size from 0 to 4;
  • Pz (Pozidrive). the angle at the top is 50 degrees; the products are an upgraded model of those previously described; are distinguished by the presence of 2 or 4 additional slots at the base;
  • Sl (Slot). straight slot, varying in width; the number in the marking means the slot width;
  • Torx (also found TX) is a hex star spline. Suitable for structures that require a high level of strength.
  • HEX. a bit that is used to fasten screws with an internal hexagon; usually used to assemble furniture.

Manufacturers analysis

In order to understand the range of products and choose the right bit for a screwdriver, you should get acquainted with the most famous manufacturers.

AEG manufactures coldfire bit sets to help increase metal strength.

Dewalt provides an extensive range of accessories, both individually and in sets.

The DT 7246 includes a PH2 with a torsion bar. Also very popular is the model called DT 71517 with bits and angle attachment. The number of revolutions is 1500 rpm, the tightening force is 150 Nm.

Quality assessment criteria

When choosing nozzles, you need to focus on the features of the work performed. One of the reasons for the rapid deterioration of equipment is misuse. It is one thing to screw self-tapping screws into wood when assembling furniture, and another thing is the installation of metal structures, where the equipment experiences increased resistance during the screwing process. An impact screwdriver must necessarily be provided with special equipment, since standard equipment will NOT be able to withstand shock loads.

To correctly approach the choice of bits, you need to Pay attention to the following parameters:

The material of manufacture affects the strength and durability. For conventional modifications, steel R-7. R-12 is used, which is distinguished by excellent resistance to interaction with any type of metal. Chromium and vanadium coatings are added to protect against corrosion. The strongest are tips with a titanium-nitride coating of a golden hue. Bits with titanium and tungsten plating have also shown themselves well in practice. For overly active use, experts recommend diamond-coated nozzles, due to which the chance of grinding the edges of the working area is reduced.

How To Choose Bits For A Screwdriver

Processing technologies. Milling and forging The most popular methods. During milling, the top surface is removed to give the work area the desired shape. Forged tooling features increased strength, the material is not disturbed during production.

The hardness of the material of the screwdriver bit ranges from 58-60 HRC. Soft attachments wear out faster, they are most of all designed for hard mounts, as they are resistant to damage. Hard ones will last longer, but rather fragile.

Design features. The magnetized work surface makes positioning in the slots easier, but sometimes this magnet is unnecessary. For an impact screwdriver, bits with a torsion part are suitable. Attachments are capable of Smoothing impact by withstanding high loads during operation.

Reliability rating

Manufacturing companies, which are trusted by qualified specialists, have proven themselves best in construction and renovation areas. The reliability rating is headed by the following brands:

Tips for choosing

If you are planning to purchase attachments for attaching components, follow these tips:

Focus on the material. Highest quality alloys:

  • Chromium and Molybdenum;
  • Chromium and Vanadium;
  • Tungsten and Molybdenum.

Steel bits It is not recommended to use, as they grind off almost after the first second of work.

The presence of a special coating on the bit is encouraged. Titanium, diamond or nickel are optimal materials that will not let the metal rust and will last a long time. Titanium plating is often found at Bosch.

It is advisable to buy products with a magnetic tip. Working with him will be much more comfortable. The best representative of this property is WhirlPower.

Experienced craftsmen advise taking kits from bits. It often happens that there is a lack of a certain mount for work. Therefore, it is best to immediately stock up on a set of 30-50 attachments of various sizes and shapes. However, which bits are best to buy for a screwdriver is up to you.

How to choose bits for a screwdriver

Additional parts for a power tool are qualitatively important as well as the tools themselves. A good result when using a drill-driver, for example, is achieved by using high quality bits.

Small-format parts and their big role

Construction and installation processes have been simplified due to the emergence of a huge amount of fasteners. Modern electric screwdrivers or screwdrivers allow quick connection of elements using fastening parts.

Nails, which were mainly used as the only existing fasteners in the old days, have now faded into the background. Everyone, from hobbyists to professional craftsmen, prefers to use screws and screws. These fasteners are extremely popular today.

However, for their even arrangement and rigid attachment to the mounted surface of sheet material or other connected elements, good nozzles are needed.

In other words, bits. Without them, any screwdriver, even the most practical, becomes useless.

Hence the conclusion, it is necessary to have an idea of ​​the existing types of nozzles in order, if necessary, to make the right choice.

Things to consider when choosing bits

Industrial-made bit sets can be purchased separately at retail outlets, but the standard sets offered for the Screwdriver already contain sets of bits of various formats.

Neglect of such requirements will lead in the future, when working with a power tool, to the constant breakdown of the bit and its scrolling into the screws.

Basic materials of manufacture

The second important factor when choosing bits for a screwdriver is the type of metal used to make them. The main role is assigned to the working parts of the nozzles.

As they are made in combination with various specialty solders, it is worth knowing Top priority alloys.

There are the following types of alloys for quality bits:

  • Molybdenum combined with chromium;
  • Vanadium with the same chromium;
  • Molybdenum and vanadium;
  • Silicon-magnesium heat (win).

The most practical bit types

When choosing a set of bits with a screwdriver, you need to pay attention to their external shape. The range of external characteristics of nozzles includes parameters of length, width and thickness, indicated in millimeters.

Taking into account the screw-in depth and hole diameters, the sets are made up of various sized elements, from the thinnest slot width (2 mm) to the densest (9 mm).

The length varies from 25 mm to 90 mm. Extra long bits are 150 mm long. Standard bit slot thickness ranges from 0.3 mm to 1.6 mm.

In the list of attachments that are most suitable for a comfortable operation of the tool, and for a quick, high-quality result, there are the following types of bits:

Designed for Slot screwdrivers. Includes screwdriver and straight slot.

Torx holes. These varieties are considered unique, customized to all construction processes where they may be required.

Philips PH-slotted cruciform bits, TIN coated with titanium nitride. These tips have a golden hue. They can withstand significant loads. They are most often used in household repair work. Large products are used for assembling large-sized furniture models, for car repairs.

Bits with a hexagonal shape with an inner hole. The sizes of the nozzles are from 1.5 to 6 mm. They are reliable and easy to use. When working with them, a person may NOT make a lot of effort. The presence of an internal hole allows the device NOT to slip.

Also interesting are the magnetic bits used in the installation and dismantling of threaded connections with a hexagonal profile. The attachments have magnetized socket heads that ensure precise fit of the fastener to the socket head. Reliability is guaranteed by the introduction in the production of steel products with a compound of chromium and vanadium.

Special and combined

Less common are special and combined attachments. The first ones are used in narrow areas, for example, in repairs:

  • With the introduction of rare fasteners, for example, triangular;
  • Household appliances;
  • Industrial equipment.

The models for attaching this material have convenient stoppers. Other options include:

  • Triangular;
  • With two “horns” (double pin)
  • Spring-loaded: twist at a 30 ° angle, which is convenient when space is limited.

Applicable standards

In addition to the form, it is advisable to understand the product standards. They belong to the bits of the basic type. The following varieties are distinguished:

  • PH standard. This is short for Philips. The slot is cross. The angle of the top is 55º. The four slots expand. There are different sizes: PH0, PH1. small, PH4. have the largest diameter. An intermediate variant, PH2, is the most common. It is almost universal. The load when using PH is distributed evenly, the probability of damage to instruments is minimal.
  • PZ standard. Abbreviation for “Pozidrive”. Very similar to the previous one, but a little more perfect. The slot is cross here. In addition to the main ribs, there are additional, slightly smaller ones. This is the difference. Due to the changes, the grip on the fasteners is better than in the PH. PZ is often used to remove stuck rusty screws or during large-scale construction. Sizes. from 0 to 4, with 2 and 3 being more common.
  • SL standard. Abbreviation for “Slot”. The slot is straight, screwdriver. The width may differ: from 0 to 7. It is indicated in the marking immediately after the standard. Such attachments are used when working with soft material, when the load is small.
  • Torx hole. Looks like a hex star. They are used when a lot of force is needed to tighten fasteners, for example, when repairing cars.

Types of products

Classification and selection of bits for a screwdriver or drill

The screwdriver is one of the most popular and necessary tools. It is used by both professional builders and ordinary people at home. The efficiency of work depends, among other things, on the correct selection of the nozzle. the bit. It will be different for each type of fastener. If there is not much work, you can purchase several common bits for a screwdriver, although it is more convenient to immediately take a suitable set.

Basic bits

Fundamentals are the most common group. Inside, cruciform models are especially popular. And you can also find:

  • Hexagonal. Suitable for hex bolts. The most common size is 4 mm. Often used for furniture mounting.
  • In the form of a wrench. For such bits, tools (drills, screwdrivers) need powerful ones. Nuts and bolts are tightened. The sizes of the nozzles are 6 to 13 mm. It must be taken into account that these numbers and the diameter of the fasteners are not the same. For example, if you need to screw a self-tapping screw with a 4.8 mm head, you will need an 8 mm bit.
