How to choose bits for screwdrivers

In appearance screwdriver bits small and not very important, but they can significantly facilitate the work of builders. However, the small size of these accessories is by no means an indicator of their low importance; moreover, huge loads affect them. As a result, many people consider bits to be disposable..

How to choose the right bits for screwdrivers for screw

To check if your bit fits a specific screw it’s not difficult at all: insert it into the head and see if it falls out. At the same time, size matching is by no means an indicator that the necessary torque will be transmitted to the product. If there is significant clearance, bit wear will be increased..

In those cases when the bit cannot be held on the screw head, even when working with a professional tool it will not be a joy. By twisting the connections, in this case, your hearing will become unpleasant sounds, accompanied by clicking the tip in the screw. This accessory is polished very quickly in work and will become worthless for nothing, except as scrap metal. In cases where the bit is rotated in the screw or slips in it, you are probably wrong to choose it. Try to identify a more suitable product..

There are a couple of incompatible Phillips screw systems. If the screw is simple, then a regular cross is located on its head, and the bit is designated Ph with one cross element. The bit is expected to match the screw head with perfect accuracy. Its lateral surfaces will be at an angle and when combined with the screw head, they should disappear in its grooves. With proper work with the bat (its direct direction), the service life of the hardware will be considerable.

The second system is posidrive, its designation is Pz. It is characterized by better transmission of high torques. The screw may have a different geometry, which may differ in narrow additional grooves that are located between the cross slots. In the hardware of this type, additional blades are used, which makes it possible to increase the force connections. The tip of the bit may come into contact with the screw at various angles. To keep intact screws and screwdriving bits, the screws are screwed at a specific angle.

By choosing the right bit size and force, you can see that the hardware is not suitable. In this case, most likely you are saving on the wrong thing. Numerous studies have shown that cheap bits have very poor pairing. At the same time, the issues of hardware hardness are not even addressed. If we talk about posidrive bits, then it’s better not to use cheap analogues at all in work.

Screw systems and selection of bits for them

Philips, posidrive and slotted screw systems are the most widely used. Screwdriver Bits practically not used for slotted screws. In furniture joints, the Philips system is often used. Such bits are protected from high loads, for a high-quality transmission of rotational force, the posidrive system is most suitable. For almost every bit, holders are needed. Holders are SDS, there are also locking systems and nozzles. If the bit is long or double, then the holder is not particularly necessary.

You can easily check how much the bit corresponds to the hardware: just put it on the screw with which work will be performed. If the connection is weak, this will lead to a flutter of the bit. When buying a bit, you can determine its type and size by the relevant indicators indicated on the package. To ensure a significant tightening torque, use the posidrive system. You can increase adhesion by using a magnetic bit holder.

Screwdriver bit prices

The use of inexpensive kits almost always leads to disappointment. When purchased, the working part of the material will almost always be unmarked. But it is from him that the quality of the work performed and their speed will largely depend on it. If you get a frankly bad tool, soon you just throw it away. In those cases when the hardening of the material is insufficient or if it does not have the necessary accuracy and shape, it is better to refuse the purchase. Remember that a less high-quality set will cost at least 300 rubles. Do not be afraid to make such a waste – after all, such bits are quite durable. A product of normal quality will cost at least 35 rubles.

If we talk about the cost, then inexpensive bits can have a good look, but only until their first use. To make a really high-quality bat, chrome vanadium is used, as well as special alloys of molybdenum and tungsten, and this affects its cost in the direction of increase. If you have quality products in front of you, you will be able to see embossed data on it about the size, manufacturer and type.

Correctly approaching the selection bits for screwdriver, you will be able to get a high quality product, working with which you will not be disappointed.
