28mm x 1320mm SDS Max 4-Cut Drill Bit 4932352782 by Milwaukee

Features:

• Especially developed robust head geometry with optimum 4 x 90 ° symmetry of carbide tip: Reduces jamming up on hitting reinforcing steel.
• Centring 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.
