The EAGLE CUTTING TOOL J100-016-D is a high-speed steel jobber-length drill bit sized at 1/4 inch. Jobber drills are general-purpose twist drills with a standard flute length proportional to the diameter, making them a go-to choice for a wide range of drilling applications in metal, wood, and plastic. At 0.5 pounds, this is a lightweight, single-piece cutting tool manufactured in the USA. It is used by electricians, plumbers, HVAC technicians, and general contractors who need a reliable bit for everyday hole-making tasks on the job site or in the shop.
The J100-016-D fits standard drilling applications where a 1/4-inch diameter hole is required. Its jobber-length geometry works well for drilling through sheet metal, conduit knockout work, structural members, and similar trade tasks. USA manufacture indicates domestic production standards for high-speed steel composition and heat treatment. This bit is suited for use in both hand-held drills and drill presses across residential and light commercial work environments.
Designed as a standard 1/4-inch jobber-length drill bit compatible with any 3/8-inch or 1/2-inch chuck hand drill, cordless drill, or drill press that accepts straight-shank twist drill bits.
Secure the bit firmly in the drill chuck before use and verify the chuck is fully tightened to prevent slippage. Always wear appropriate eye protection when drilling. Match drill speed to the material being drilled — harder materials such as steel require slower RPM compared to wood or plastic. Disconnect power from cordless or corded tools before changing bits.
