Description
Genuine Carlyle · Part no. CBD75
The Carlyle CBD75 is a 7.5mm cobalt HSS drill bit, M35 grade with 5% cobalt and ground to DIN 338, with a 130-degree split point. It is an in-between size, for opening holes up in stages towards 8mm and above, fitting grommets or fittings that need a hole a little over 7mm, and drilling stainless or hard steel.
Good to know
- Why not go straight to the final size? Stepping up in stages keeps a large hole round and on centre and puts less strain on a hand drill.
- What size hole does my fitting need? Check the fitting or its instructions for the hole size, and measure with a caliper rather than by eye.
- Is it OK in a cordless drill? Yes, with the drill on a low gear, a firm two-handed grip and the work clamped down.
Which one?
The Carlyle 7mm HSS Cobalt 5% Drill Bit (CBD7) is just under this size and the Carlyle 8mm HSS Cobalt 5% Drill Bit (CBD8) is just over, with a three-flat shank.
