Carlyle 3.2mm HSS Cobalt 5% Drill Bit (CBD32)

Description

Genuine Carlyle · Part no. CBD32

This Carlyle 3.2mm drill bit (CBD32) is cobalt HSS to DIN 338, M35 grade with 5% cobalt, with the flatter 130-degree split point used from 3mm up for a quick, self-centring start. 3.2mm is the 1/8 inch pop rivet size, so it is a common bit for riveting brackets, panels and trailer boards, and for pilot holes.

Good to know

• Will 1/8 inch (3.2mm) pop rivets go in this hole? Yes: they go in a 1/8 inch or 3.3mm hole, and 3.2mm drills the 1/8 inch size.
• How do I drill out an old rivet? Centre the bit on the rivet head and drill just through the head, then knock the rest of the rivet out with a punch.
• Any tips for stainless? Low speed, firm steady pressure and cutting fluid; let the bit rub and the metal work-hardens and blunts it.

Which one?

The Carlyle 3mm HSS Cobalt 5% Drill Bit (CBD3) is just under this size and the Carlyle 3.5mm HSS Co5 Drill Bit 3.5mm (CBD35) just over. For 3/16 inch rivets, see the Carlyle 5mm HSS Cobalt 5% Drill Bit (CBD5).
