Value Collection C87764 Jobber Drill 31/64 in Hss M7

Product Description

The VALUE COLLECTION C87764 is a jobber-length drill bit ground from M7 high speed steel and finished with a black oxide and gold oxide coating for surface hardness and corrosion resistance. The bit measures 31/64 inches (0.4844 inches decimal) in diameter with a 135-degree split point that reduces walking on entry and lowers thrust requirements compared to a conventional 118-degree point. At 5-7/8 inches overall length with a 4-3/8-inch flute length, it fits standard three-jaw chucks in corded and cordless drill drivers. Right-hand cutting direction and a regular spiral flute pattern make this bit appropriate for general-purpose metalworking, fabrication, and maintenance drilling in trade and shop environments.

This drill bit is suited for heavy-duty production and maintenance applications where a consistent, repeatable hole size in the 0.4000 to 0.5000 inch decimal range is required. The straight cylindrical shank matches the 31/64-inch body diameter, making it compatible with standard drill press chucks and hand-held drill drivers used by electricians, plumbers, HVAC technicians, and fabricators drilling through ferrous and non-ferrous metals, plastics, and similar materials. It is sold individually.

Key Features

• M7 high speed steel construction rated for heavy-duty drilling in metal and hard materials
• 135-degree split point reduces bit walking and self-centers on entry without a center punch
• Web-thinned, tapered web configuration lowers cutting resistance and reduces heat buildup
• Black oxide and gold oxide dual coating improves surface hardness and extends service life
• Regular spiral flute clears chips efficiently in through-hole drilling applications
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber drill bit for use in standard drill presses and hand-held drill drivers accepting a straight cylindrical shank in the 0.4000 to 0.5000 inch decimal diameter range.

Installation Notes

Installation of this bit is performed by machinists, fabricators, and trade professionals using a standard keyed or keyless chuck. Secure the straight shank fully in the chuck before operation and verify the bit runs true before drilling. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat. Always wear eye protection and secure the workpiece before drilling.
