Value Collection C87753 5/16 in Hss Jobber Drill Bit 2-pack

Product Description

The VALUE COLLECTION C87753 is a 5/16-inch high-speed steel jobber drill bit designed for general-purpose drilling in metal, wood, and composite materials. Built from M7 grade HSS, this bit features a 135-degree split point that reduces walking and allows faster penetration with less feed pressure. A black and gold oxide coating adds surface hardness and mild lubricity. The straight cylindrical shank fits standard three-jaw drill chucks. This bit is sold in a package of two and is suited for use by machinists, maintenance technicians, pipefitters, and general trade professionals who need a reliable, heavy-duty jobber-length drill in a common fractional size.

This drill bit is appropriate for shop, field, and maintenance applications where 5/16-inch through-holes are required. Typical uses include drilling pilot holes for fasteners, conduit knockouts, pipe hangers, and sheet metal work. The right-hand spiral flute and web-thinned split point make it well-suited for hand-held drill operations as well as drill press work. The 4-1/2-inch overall length covers standard jobber-reach requirements without excessive deflection. Each package contains two bits, making it practical for stocking a job box or parts inventory.

Installation Notes

A licensed or qualified tradesperson should confirm the correct bit size and material rating before drilling into structural or pressurized components. Secure the workpiece and ensure the chuck is fully tightened before operation. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Follow applicable safety standards and wear proper eye protection during use.
