Carlyle 6mm HSS Cobalt 5% Drill Bit (CBD6)

Description

Genuine Carlyle · Part no. CBD6

Carlyle CBD6 is a single 6mm drill bit made from M35 cobalt high speed steel, 5% cobalt, to DIN 338, with a self-centring 130-degree split point. A 6mm hole is an everyday size for fixings, cable ties through brackets and mounting holes, and the cobalt lets the same bit go through stainless steel and tougher alloys.

Good to know

• Can I use it in masonry for wall plugs? No. It is a metal drill; use a masonry bit for brick and block, and keep this one sharp for steel.
• How do I stop it overheating in steel? Medium-to-low speed, steady pressure that produces curly swarf rather than dust, and a few drops of cutting fluid.
• Do I need a pilot? In thin steel the split point starts on its own; in thick plate a smaller pilot hole first makes the job easier.

Which one?

For M6 threads, the tapping size is the Carlyle 5mm HSS Cobalt 5% Drill Bit (CBD5). The Carlyle 6.5mm HSS Cobalt 5% Drill Bit (CBD65) is the next size up.
