Milwaukee Metal Drill HSSCo D338 10.5mm-1 Piece (4932363281)

Description

Genuine Milwaukee · Part no. 4932363281

A single 10.5mm Milwaukee HSS-Co metal drill bit, ground from 5% cobalt high speed steel to DIN 338 with a QUAD EDGE 135° split point and a three-flat shank. 10.5mm is a useful size on cars: the tapping drill for an M12 x 1.5 thread and a close clearance hole for an M10 bolt.

Good to know

• Can I re-tap a stripped thread with it? If you are cutting a new M12 x 1.5 thread, yes, this is the tapping size; drill square to the surface, then tap with cutting oil, backing the tap off every turn or so.
• Will it go through a stainless bracket? Yes, cobalt bits are made for steels over 1000 N/mm² such as stainless; stainless work-hardens if the bit rubs, so use firm pressure and a slow speed.
• Do I need a pilot hole at this size? In thick steel, a small pilot first makes the job easier and keeps the hole on the mark, though the split point does start cleanly in thin sheet.

Which one?
