M35 Cobalt Twist Drill Bit Set, 13-Piece 1/16-1/4 Inch HSS Bits with 135-Degree Split Points
This M35 cobalt twist drill bit set covers thirteen frequently used fractional sizes for clean drilling in stainless steel, cast iron, copper, aluminum, softer metals, plastic and wood. A 135-degree split-point geometry helps each bit center quickly with less walking, while spiral flutes clear chips as the cutting edges advance.
The indexed case includes 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 11/64, 3/16, 13/64, 7/32, 15/64 and 1/4-inch straight-shank bits. Hardened and polished HSS cobalt construction supports sharp, stable cutting when used at an appropriate speed with lubrication for the material. The listing also contains many other sets and single-size packs, so confirm the exact selected size range and count.
