Milwaukee Metal Drill HSSCo D338 12.0mm-1 Piece (4932363284)

Description

Genuine Milwaukee · Part no. 4932363284

A single 12mm Milwaukee HSS-Co drill bit in 5% cobalt high speed steel to DIN 338. The QUAD EDGE tip has a 135° split point and four cutting edges that make small chips, and the shank has three flats. 12mm is the tapping drill for an M14 x 2 thread and a useful size for opening up holes in brackets.

Good to know

• What speed should I run a 12mm bit at? Slower than smaller bits: a larger bit's edge travels faster at the same speed, so keep the drill on a low setting with steady pressure and cutting oil to stop it overheating.
• Will it fit my drill? Its three-flat shank suits drills with a chuck that opens to at least 12mm; check your chuck's capacity first.
• Can I enlarge an existing hole with it? Yes, but clamp the part firmly, as opening out a hole lets the bit grab; stepping up through sizes is smoother than one big jump.
