Dual Flute construction. Gold surface treated. Expands holes 3/16" - 1/2". 6 sizes - 1 drill. High Speed Steel KnKut Step Drills are made from special moly alloy steel and gold surface treated for maximum lubricity. Dual flute construction drills clean accurate holes in thin materials.

When drilling steel with 1/8" or greater thickness, a starter hole of the smallest step diameter will speed the drilling process.
