Screwdriver Bits

Screwdriver bits are simply short hexagonal shafts with a particular tip type, used with other tools to drive screws, either by hand or powered.

For hand driving, screwdriver bits can be used in conjunction with a special type of screwdriver that allows different tip types to be quickly swapped. Great if you encounter a whole range of screw types frequently.

This type of screwdriver is snappily called a 'Bit holder/Driver' and has a magnetised docking system for the bit, to hold it in place (see image below).

 

Where screwdriver bits really come into their own is where lots and lots of screws need to be undone.

They can then be used with a power tool (usually a cordless drill driver) to quickly and repeatedly drive screws. This method is much faster and less tiring than using a screwdriver with the added benefit that a worn bit can be replaced quickly and relatively cheaply.

It's even faster if the bit is held in a drive adapter - the bit can be changed and replaced without having to undo the chuck. This type of drive adapter holds the bit in place with a magnet.

With this type of drive adapter, there is a risk that the bit could be left stuck in the screw head, which can be irritating. To make sure this cannot happen, we offer a quick lock drive adapter. This positively locks the bit in place.

 

Blue Steel Impact Bits

Due to the increasing popularity of impact drills, there is a need for super tough impact bits which can withstand the pressures that impact drills exert.

The Blue Steel Impact Bits are manufactured from a specially formulated V8 alloy steel and a special hardening process means that these bits are immensely tough.

In addition to the material and hardening techniques used, these impact bits feature a torsion zone which flexes to absorb high amounts of torque.

 

​They are available in PZ, PH, Slotted, Hex, Torx, and Anti-Tamper Torx.
