Screwdriver Bits

Specifications

-  chrome-vanadium steel is used for production of regular screwdriver bits with hardness of 50 – 54 HRC

-  S2 is a strong alloy with hardness of 60 – 62 HRC, notable for its high level of wear-resistance; the  S2 screwdriver bits are intended for heavy-duty applications

-  a titanium coating adds to the higher strength of a bit, improves its seizure with a screw, providing a longer service life

Work profiles

Slotted

The most simple and commonly used profile of inner work slot having certain inherent drawbacks.

This profile cannot prevent a bit tip from side shifting and requires a significant fixing force. In case the size of a bit head is lesser than the corresponding screw slot, there exists a high possibility of damaging the slot. During work the screw head slot is easily clogged, thus increasing a chance of the bit slipping from slot and distortion of the slot.

Philips

This cross shape has some advantage as compared to a slotted profile: the conical shape allows a tight hold of a screw due to the force of friction. Philips profile becomes easily clogged and likewise easily cleared. A lesser fixing force is required which is applied right along its axis. There exists a possibility of distorting a Philips slot in the course of work.

Inner hexagonal shape

A very reliable shape of work profile with regard to its stability to a higher torque applied. No fixing force is required; a distortion of this profile is practically excluded.

Posidrive

Minor intermediate ribs increase the total contact area with a screw, ensuring a more uniform force distribution when driving the screw in. This allows application of higher torque values. Additionally, there is a lesser chance of bit slipping from the Posidrive profile, and of profile clogging.

Inner TORX

This profile has all the advantages of the inner hexagonal profile and in some ways even exceeds it. The absence of tension concentration points in the corners of a screw head profile makes its structural strength significantly higher. It is considerably less deformed at high operational forces. A mismatch between sizes of the bit and screw work profile is impossible. Owing to an optimal force application through a drive, an ultimate possible torque is achieved. Slipping of a bit is excluded.

Bit holder

Magnet-type bit holders are the most easy to use. The magnet lock magnetizes the bit strongly enough to hold a fastener/screw at its tip. The magnet lock can also attract swarf and dust that are blocking the holder opening and prevent tight fitting of a bit shank. That is why we recommend cleaning the bit holder after every use.

Advantages

-  the powder technology used for manufacturing allows to combine high hardness with high mechanical strength, ensuring a high level of performance characteristics

-  fine-dyspersated abrasive coat prevents slipping of a bit from a screw work profile

-  special ribs also prevent slipping of a bit; due to these ribs a bit is gripped tightly in the screw head slots

-  optimum torque value without extra efforts

-  a procedure of driving screws in and out is fast, easy and neat

-  low wear and high breaking strength

-  the perfectly maintained preset dimensions

-  the range line comprises the most commonly required types and sizes of bits

-  made of high-quality materials

-  a long service life

Application area

Driving various types of screws (regular, self-tapping, wood-screws) and other fasteners into hard and soft materials
