About This Item

The Carbide AERO-D-REAM is a high performance tapered drill/reamer for composites.

Features & Benefits:

  • Straight Flute: Limits peel-up at hole entrance
  • Elongated double-angle geometry: Reduces thrust and limits exit delamination
  • Ultra-fine micrograin carbide: Smaller grain size yields improved wear resistance and better coating adhesion properties for extended tool life
