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.
