Drill-Mills, 90 Degree, 2-Flute, Cobalt, Individual Sizes
  • 90 Degree angle
  • Cobalt steel
  • For spotting, chamfering, grooving

Drill-mills work best on aluminum.

They can be used for spotting holes instead of using a center drill; and are great for chamfering edges.

Use a drill-mill to make a 90 degree angle groove.
