Chicago-Latrobe 77655 118 Degree Carbide Tipped Jobber Length Drill Bit 9/32 in

Jobber-length carbide bit for general drilling

This Chicago-Latrobe 77655 drill bit has a jobber-length flute and a conventional 118-degree point. The carbide tip is designed for drilling steel, cast iron and other hard materials. The bright uncoated finish reduces friction in softer metals. It suits maintenance technicians and metalworkers who need a durable fractional-size bit.

Carbide tip and uncoated finish change tool life

The carbide tip resists wear far longer than high-speed steel when cutting abrasive alloys. The bright finish prevents coating build-up in aluminium and copper. No coolant holes are present, so the user must supply external lubrication or peck drilling. The accessory bundle contains only the single bit in its protective tube.

Straightforward chuck fit with common pitfalls

The 9/32-inch shank fits standard three-jaw chucks without adapters. The 118-degree point starts cleanly on flat surfaces but can wander on curved pipe unless centre-punched. Overheating dulls the carbide edge quickly, so steady feed and cutting fluid are essential. The bit is not coolant-through, so deep holes need frequent withdrawal to clear chips.
