SOLID CARBIDE 8 FACET DRILLS

 

Onsrud's drills for composite materials incorporate an 8-facet point design that reduces cutting forces and eliminates delamination when exiting the material. The solid carbide drills are wear-resistant and can be coated for improved tool life. The drills can be used on carbon fiber and other composite materials where clean, delamination free holes are desired.

 

Custom sizes can be made upon request.

WHAT IS A 8 FACET DRILL?
