PRO GOLD Cobalt 135 Degree Drill Bit 5/16" Diameter
PRO GOLD Cobalt High Speed Steel Drill Bits are designed to cut through extremely hard metals, including stainless steel. No center point is needed, as these 135° quick cut points are self-centering and penetrate faster with less pressure. Will not walk or wander at the starting surface. Extremely heat-resistant, these drill bits are most efficient in drills that operate at 1500 RPM or more. Cobalt high speed steel drill bits offer a 12X life rating, compared to standard 118° point drill bits.
