Carlyle 5mm HSS Cobalt 5% Drill Bit (CBD5)

Description

Genuine Carlyle · Part no. CBD5

Carlyle CBD5 is a 5mm cobalt drill bit to DIN 338, M35 high speed steel with 5% cobalt and a 130-degree split point. 5mm is the tapping drill for M6, one of the most common bolt sizes on cars and trailers, so it is the bit to use before tapping an M6 thread, as well as for general holes in steel and stainless.

Good to know

• Which tap goes with a 5mm hole? An M6 coarse thread tap; tap slowly with cutting fluid and back the tap off often to break the swarf.
• Does it suit 3/16 inch pop rivets? Those go in a 3/16 inch or 4.9mm hole, so 5mm gives a slightly free fit; check the rivet's pack if it gives a size.
• Can it drill stainless? Yes. Run it slower than for mild steel, keep the pressure on and use cutting fluid so it doesn't glaze.

Which one?

For an M5 thread, the Carlyle 4.2mm HSS Cobalt 5% Drill Bit (CBD42) is the tapping size. For an M5 clearance hole, the Carlyle 5.5mm HSS Cobalt 5% Drill Bit (CBD55) is next up.
