Makita P-77811 Concrete Drill Bit, Zentro SDS-Max, 20 x 320mm, 4 Cutting Edges

Features

• Adapted for SDS-MAX Hammers
• Specially developed robust head geometry ensures that even the toughest applications can be mastered.
• Carbide Tip The optimal 4x90° carbide cutting edge symmetry prevents seizing upon 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.
