Onsrud 67-811 3/16" Carbide TiN 118° Jobber Drill Bit

Onsrud 67-811 Carbide Drill Bit

The Onsrud 67-811 is a jobber-length drill bit made from solid carbide with a titanium nitride coating. It targets machinists and fabricators who need a rigid tool for high-speed drilling in abrasive or hardened materials where high-speed steel wears too quickly.

3/16 inch diameter with 118-degree point

The 3/16 inch diameter (.1875 decimal equivalent) suits general-purpose holemaking in ferrous and non-ferrous alloys. The 118-degree eight-facet point centres accurately without a pilot hole, but the bright uncoated finish and lack of coolant-through channels limit chip evacuation in deep or high-volume production runs.

Replaces worn high-speed steel jobbers

This bit upgrades from standard high-speed steel jobbers when tool life and hole finish become critical in tough alloys. The jump is worth it for shops drilling stainless steel, titanium or composites where carbide holds size longer; it is not for buyers who need coolant-fed drilling or coated bits for extended runs in aluminium.
