Description

Makita SDS Max rotary Hammer bits feature tips that stay sharper longer and deliver more holes within specification than competitive bits.

  • Premium Range
  • 4 cutter new carbides for better performance in reinforce concrete.
  • Specially developed robust head geometry ensures that even toughest applications can be mastered.
  • The optimal 4×90 deg 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.
  • Centring point with 130 deg 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.
  • Adapted for SDS-MAX Hammers
