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 (steel, brass, aluminum, copper) up to 1/8" (3.2 mm) thick as well as in plastic and wood.
No center punching or pilot hole drilling is required on most sizes.
The bits are easy to keep sharp.. and the hole size is easily determined by the diameter markings that are permanently laser-etched in the flute areas.
Fabricated of rugged, high-speed steel in sizes to fit 1/4", 3/8" or 1/2" chuck of portable electric drills and drill presses.
Unlike standard-point twist drills with two cutting surfaces, the single-flute design of the Klein-Unibit drill bit eliminates skidding. Single cutting-edge design assures penetration of softer materials at
the proper speed, stops "hogging-in", helps to eliminate chatter and vibration. Hole is de-burred automatically by the next succeeding size. You can feel and see each step as the bit penetrates. Hole-size diameters are permanently laser-etched
in the flute area of each bit, and offer quick and positive identification of each hole-size step to help eliminate user errors.
Klein-Unibit drill bits are real time savers in electrical work. Rugged, high-speed steel drills steel, brass, aluminum, and copper sheet with ease. No center punch or pilot holes required for most sizes.
