VULCAN 1396720 Colbalt Drill Bit Set

Product Description

Colbalt has a thicker core than a standard drill bit, providing the user with maximum strength; helping eliminate side-load breakage. We added a unique parabolic flute that keeps the bit running cool. Excellent for drilling on curved surfaces, requires less effort to drill and is highly recommended for use with portable drills. Applications include a variety of metals and synthetic materials. Performs best in steel, stainless steel, cast iron, titanium, nickel, and copper materials.
