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