Milwaukee Metal Drill HSSCo D338 11.0mm-1 Piece (4932363282)

Description

Genuine Milwaukee · Part no. 4932363282

A single 11mm Milwaukee 5% cobalt HSS-Co drill bit made to DIN 338, with a 135° split QUAD EDGE point that starts without wandering. 11mm is the standard clearance hole for an M10 bolt, the size you need when fitting brackets, a bike rack plate or a towbar electrics bracket through steel.

Good to know

• Why drill 11mm for an M10 bolt? A clearance hole slightly larger than the bolt lets it pass through and line up with the nut or captive thread without binding, while still giving the head and washer plenty to bear on.
• How do I stop a big bit grabbing as it breaks through? Ease the pressure as you feel it start to break through thin steel, and clamp the work; a bit this size can snatch a loose bracket round.
• Does it suit hard steels? Yes, the cobalt alloy keeps its edge in stainless and steels over 1000 N/mm²; drill steel slowly with steady pressure and cutting oil.
