1/8" to 1/2" Unibit High Speed Step Drill - No Pilot Hole Required

Perfect for drilling multiple size holes in thin sections of metal, plastic and wood using a single bit.  Each Klein Unibit does the work of many drill bit sizes.  Drills round holes in most metals up to 1/8" thick as well as plastic and wood.  No center punching or pilot hole drilling is required for most sizes.  The bits are easy to keep sharp and hole size is easity determined by the diameter of the markings that are permanently laser-etched in the flute areas.  The single-fluted design eliminates skidding and makes for easier resharpening.
