Eagle Cutting Tool J100-020-D Hss Jobber Drill 5/16 in

Product Description

The EAGLE CUTTING TOOL J100-020-D is a 5/16-inch high-speed steel (HSS) jobber-length drill bit manufactured in the USA. Jobber-length bits are the standard general-purpose drill geometry used across metalworking, mechanical contracting, plumbing rough-in, and electrical trade work. The HSS construction provides the hardness and heat resistance needed for drilling through mild steel, cast iron, aluminum, wood, and most plastics encountered in daily trade use. At 1.2 pounds, this is a solid, trade-grade tool suited for both bench drill press work and handheld power drill applications.

This drill bit is appropriate for residential and light commercial applications where a standard jobber-length 5/16-inch hole is required. Common use cases include drilling pilot holes for anchors, clearance holes for fasteners, conduit knockout preparation, and structural framing rough-in. It is well suited for HVAC, plumbing, and electrical trades that regularly need a reliable general-purpose drill bit on the job site or in the shop.
