Eagle Cutting Tool J100-028-D Hss Jobber Drill 7/16 Inch

Product Description

The EAGLE CUTTING TOOL J100-028-D is a 7/16 inch high-speed steel (HSS) jobber-length drill bit manufactured in the USA. Jobber-length drills are the standard flute-to-shank proportion used across the trades for general-purpose through-hole drilling in metal, wood, and plastic. HSS construction gives the bit the hardness and heat resistance needed for drilling mild steel, cast iron, aluminum, and similar materials encountered in HVAC, plumbing, and electrical rough-in work. This bit is suited for use in standard drill presses, hand drills, and magnetic base drills.

The J100-028-D is appropriate for residential and light commercial applications where a reliable, general-purpose drill bit is needed. Common use cases include drilling mounting holes in sheet metal ductwork, conduit hangers, pipe straps, electrical enclosures, and structural framing members. The 7/16 inch diameter makes it a go-to size for clearance holes for 3/8 inch fasteners and anchor bolts. It is used by HVAC technicians, electricians, plumbers, and general contractors on the job site or in the shop.

Installation Notes

Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Secure the workpiece before drilling and use proper speeds for the material and bit diameter per standard machining tables. Wear appropriate eye protection in accordance with applicable safety standards. Inspect the cutting edge before use and discard the bit if the edge is chipped or significantly worn.
