Chicago-Latrobe 50076 17/32 in 135 Degree Cobalt Drill Bit

Chicago-Latrobe 50076 Cobalt Drill Bit

This Chicago-Latrobe 50076 jobber-length drill bit is made from cobalt steel for drilling hard metals. It features a 17/32 inch diameter with a decimal equivalent of .5313 inches. The 135 degree split point reduces walking and starts holes cleanly without a centre punch. It is a non-coolant through design with zero coolant holes for standard machining applications.

Suited for metalworkers drilling stainless steel

The cobalt construction resists heat and wear when cutting tough materials like stainless steel, titanium or high-strength alloys. The fractional inch sizing fits imperial tooling requirements common in maintenance and fabrication shops. Builders who need metric dimensions, carbide tips for abrasive composites, or through-coolant channels for deep-hole drilling should look at other tooling options.

Holds edge during extended drilling cycles

Cobalt alloy retains hardness at higher temperatures generated by sustained cutting in tough metals. The 135 degree split point geometry maintains centring accuracy over repeated holes without frequent resharpening. Straw bronze surface finish indicates heat treatment that supports consistent chip evacuation during prolonged use in ferrous materials.
