The EAGLE CUTTING TOOL J100-017-D is a high-speed steel (HSS) jobber-length drill bit sized at 17/64 inch. Jobber drills are the standard general-purpose twist drill used across metalworking, fabrication, and maintenance trades. HSS construction provides the hardness and heat resistance needed to cut through mild steel, aluminum, copper, brass, and most plastics without premature dulling. At 17/64 inch, this bit is a common size for clearance holes, tapping prep, and through-hole work on structural and sheet metal applications. Electricians, plumbers, pipefitters, HVAC techs, and general maintenance professionals keep jobber drills like this on the bench as everyday workhorses.
This drill bit is suited for use in hand-held power drills, drill presses, and magnetic base drills in both residential and commercial job-site environments. It is a domestic USA-manufactured bit, which is relevant for shops and contractors with sourcing requirements. The 17/64 inch diameter is frequently called out in drilling charts for No. 10-32 and 1/4-20 tap clearance holes, making it a staple in general mechanical and trade work.
Designed as a general-purpose replacement or stock drill bit compatible with standard 3/8 inch or 1/2 inch keyed and keyless drill chucks used in hand drills and drill presses.
Installation of this drill bit is performed by machinists, fabricators, and trade professionals using standard drill equipment. Secure the bit fully in the chuck and verify it is centered before use. Always wear appropriate eye protection when drilling. Match spindle speed to the workpiece material — harder materials require lower RPM to prevent overheating the cutting edge.
