Makita P-77970 SDS Max Concrete Drill Bit, 28mm x 570mm x 450mm, with a 4-cutter head

Features

• Adapted for SDS-MAX Hammers Power.
• Specially developed robust head geometry ensures that even the toughest applications can be mastered. Carbide Tip.
• The optimal 4×90° carbide cutting edge symmetry prevents seizing up on hitting reinforcing steel.
• Large, robust secondary cutters with dynamically curved cutting tips actively support the main carbide tip during fast drilling.
• The drilling debris is transported fast in the large-volume flute geometry.
• The centering point with a 130° point angle ensures highly accurate, precise drilling and guarantees optimal drill guidance.
• The individual wear marking is an indicator for evaluating the dimensional stability of the anchor holes.
• The reinforced-core flute achieves the optimum between volume and break resistance.
• Vibrations are dampened and resulting in more impact energy on the carbide tip.
• The SDS max-4 Drill Bit is equipped with a 4-cutter head and delivers a long lifetime in concrete.
