Screw-On Modular Heads & Modular Extensions

Dapra's Line of Screw-On Heads Fits Industry Standard Cutting Systems

Ball Nose Modular Head
  • Compatible with ISO standard modular cutting systems
  • Close-tolerance mounting of heads minimizes runout and maximizes rigidity
  • Provide significantly more effective reach than solid end mills
  • Use standard inch wrench flats, no special metric wrenches needed

Dapra's Modular Extensions Provide Even More Cutting Options

Ball Nose Modular Extension
  • Made of high-density tungsten, providing extra resistance to deflection and chatter
  • Machined on both ends; can be cut in half and used with two different modular heads
  • Metric shank diameter provides clearance for each inch size modular head
