Milwaukee 4932352767 20mm x 1320mm SDS Max 4-Cut Drill Bit - W164739

Features:
Especially developed robust head geometry with optimum 4 x 90 & deg; symmetry of carbide tip: Reduces jamming up on hitting reinforcing steel
Centering point with 130° point angle: Easy spot drilling with pinpoint accuracy and ensures optimum guidance during drilling
Robust secondary cutter with dynamic curved cutting edge: Supports the primary cutter for faster drilling
Shorter spiral windings: This allows for faster transport of drilling dust from the head to the flute = Less wear and heat build-up at the tip
Unique carbide tip: With more carbide on all diameters and extra carbide on ø > 32mm
Wear mark on both sides of primary cutter: Guarantees diameter accuracy (i.e. for anchor fittings) and acts as a life time indicator in warranty cases
Deep flute shoulders: High volume dust removal for optimum drilling
Less wear and heat build-up
Low vibration drilling performance: Comfortable drilling ensures less stress for man and machine
Special surface treatment: Shot blasting provides a smooth surface and densifies the surface structure and makes the bit more wear resistant
PGM Conformity: Guarantees precise holes for anchor fitting over the entire life time of the drill bit
