Features and Benefits:
- Made from special moly alloy steel and gold surface treated for maximum lubricity
- Dual flute construction drills clean accurate holes in thin materials
- Use for all thin metals, rigid plastics such as Plexiglass and wood or composite materials with a thickness equal to or less than the step thickness
- Enlarges holes 1/4" - 3/4"
9 sizes, size increments: 1/16". When drilling steel with 1/8" or greater thickness, a starter hole of the smallest step diameter will speed the drilling process.
