Review on ACTOOL Double Spiral Industrial Drill Cutting Tools by Andrew Kay

Revainrating 5 out of 5

The spiral blade is much better.

Drills fast. But the tip can quickly become blunt. 1/8 ago first with a cheap drill. then in this step the drills are cut to 1/2 inch in seconds.

Pros
  • Manufactured from industrial grade M2 HSS, heat treated for maximum strength
Cons
  • Expensive
