Dapra's Carbide Core Modular Extensions Are Ideal for Standard Inch End Mill Holders

Modular Head Extension
  • Cylindrical inch shanks, providing adaptation for end mill holders, milling chucks and heat-shrink holders
  • 3 sizes to accommodate modular head sizes from 3/4" to 1 1/2"
  • Carbide core for enhanced vibration dampening capability; reduced deflection and improved rigidity
  • Optional add-on extensions for additional 2" reach – screw on to base extensions (for 3/4" to 1 1/2" modular heads)
  • Thru-coolant for delivery of air or coolant right at the cutting edge
