Fast4

The Fast4 from C.K is the perfect drill bit for professional electricians or anyone who needs to cut fast repetitive holes.

​

Like flat bits, Fast4 bits have small shank diameters relative to their boring diameters, so the shanks are provided with hexagonal flats to prevent them slipping in the drill chuck.

In addition to this, the shanks have a recess machined into the hex drive – this is a quick-lock docking facility that can be used with products like the C.K bit extension drive or the C.K Quick-lock direct drive adapter to change bits without having to undo the chuck or clamping screws.

​

The 32mm size Fast4 has a larger hex shank and therefore cannot be used with quick- lock systems on impact drivers.

​

Fast4 are available in sizes 16, 20, 22, 25 and 32mm.

​

It's specially designed to offer fast, clean drilling through timber. With twice the cutting edge of an equivalent sized flat bit. The Fast4 features a centre screw to pull the bit through the wood, blade end spurs for clean cutting and four flutes for fast debris ejection.
