4932352751 - Drill bit for concrete SDS-Max MX4, 4 cut, 12 x 400/540 mm

• Large carbide tip with patented rebar chamfers.
• Ensures lower vibration and optimised drilling performance when hitting reinforced steel equalling longer life time.
• Especially developed robust head geometry with optimum 4 x 90° 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.
• Big, robust secondary cutter with dynamic, curved cutting edge. Supports the primary cutter for faster drilling.
• Shorter spiral windings. For faster transport of drilling dust from the head to the flute = Less wear and heat build up at the tip.
• Innovative, unique carbide tip. With more carbide on all diameters and extra carbide on Ø > 32 mm.
• Wear mark on both sides of primary cutter. Guarantees diameter accuracy i.e. for anchor fittings.
• Life time indicator in warranty cases.
• Patented reinforced flute geometry. Lower vibrations for smoother drilling. Stronger flute means less breakages.
• Better transfer of hammer energy to the tip.
• Deep flute shoulders. High volume dust removal for optimum drilling speed 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.
