Enlarge existing holes. Drill through sheet metal, hard steel, acrylics and brass. Self-centering 3-flats on shank. Twice the life of a standard drill bit.

Spiral fluted PATENTED stepped-tip drill bits that simply outperform every conventional drill bit design in nearly all materials. Patented design eliminates bit walk and the need for pilot holes. Excels on hard alloys, sheet metal, and imperfect parts that are difficult to start drilling into. Precision ground from heat treated quality M2 High Speed Steel and Onyx oxide coated to prevent chip build-up. Three-flat shanks, reduced shanks above 38, and mechanics length for superior access in cramped spaces.

Made In USA. Great for hard steel, brass, sheet metal and acrylics. Split point step design starts on contact, self-centers and eliminates the need for a center punch. Can be used to enlarge existing holes without damaging the point. Mechanics length provides a shorter sturdier construction.
