Milwaukee Metal Drill HSSCo D338 3.0mm-2 Piece (4932363253)

Description

Genuine Milwaukee · Part no. 4932363253

A pack of two 3mm Milwaukee HSS-Co metal drill bits, 5% cobalt to DIN 338, with a 135° split point and four cutting edges. Small bits are the ones that snap, so the pair gives you a spare. Use them for pilot holes before a bigger bit, holes for trim self-tappers, and drilling into hard steel.

Good to know

• Why drill a 3mm pilot first? A small pilot hole guides a larger bit straight onto your mark and cuts the effort needed in thick steel, so the bigger bit drills a rounder, more accurate hole.
• How do I stop a small bit snapping? Keep the drill straight, don't lean sideways on it, let it cut at a steady speed and back it out to clear chips; a sudden snatch at break-through is what breaks most small bits.
• Will it drill stainless? Yes, the 5% cobalt alloy keeps its edge in stainless and steels over 1000 N/mm², provided it cuts rather than rubs.
