5/32 In. X 3-1/8 In. Cobalt M42 Drill Bit

Bosch Cobalt M42 Metal Drill Bits are engineered with upgraded M42 alloy, containing 8% cobalt. These hard-core cobalt bits deliver 10X life vs. standard bits, are jobber length and withstand high-heat applications. The thick web-helix design delivers fast material removal and increased stability. Bits that are 1/8 In. and larger feature a split point; bits 3/16 In. and larger feature a three-flat shank, for better bit grip. These cobalt drill bits provide superior performance in stainless steel and can be used to drill cast iron, titanium and other hard or abrasive metals.
