Makita Accessories, SDS-MAX ZENTRO Drill Bits (25x320mm) P-77914

Adapted for SDS-MAX Hammers - Ø 12 to 15 mm : 2 cutter - Ø 16 - 50mm: 4 Cutter new carbides for better performance in reinforce concrete - Ø 32mm to 50mm: 4 Cutter and additionally reinforced carbide tip - Specially developed robust head geometry ensures that even toughest applications can be mastered. - Carbide Tip The optimal 4x90° carbide cutting edge symmetry prevents seizing up on hitting reinforcing steel. - Fast Drilling Large, robust secondary cutters with dynamically curved cutting tips actively support the main carbide tip during fast drilling. - Flute The drilling debris is transported fast in the large-volume flute geometry. - Accuracy Centering point with 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. - Impact Energy 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.
