Carlyle 6.5mm HSS Cobalt 5% Drill Bit (CBD65)

Description

Genuine Carlyle · Part no. CBD65

The Carlyle CBD65 is a 6.5mm HSS cobalt bit in M35 steel (5% cobalt), made to DIN 338 and ground with a 130-degree split point. At 6.5mm you are into bigger holes, for bolts, cable grommets and fittings through steel brackets, plates and stainless, where the cobalt keeps the cutting edges sharp for longer.

Good to know

• Should I pilot drill first? For a hole this size in metal, yes: a smaller pilot hole first makes the bigger bit cut easily and stay on centre.
• What speed should I use? Slower than for small bits, as larger diameters cut faster at the edge; too much speed overheats the tip.
• How do I hold small parts safely? Clamp them in a vice or to the bench; a bit this size can grab and spin a loose bracket.

Which one?

The Carlyle 6mm HSS Cobalt 5% Drill Bit (CBD6) is a touch smaller and the Carlyle 7mm HSS Cobalt 5% Drill Bit (CBD7) a touch bigger.
