Eagle Cutting Tool J100-031-D Hss Jobber Drill 31/64 Inch

Product Description

The EAGLE CUTTING TOOL J100-031-D is a 31/64-inch high-speed steel (HSS) jobber-length drill bit manufactured in the USA. Jobber-length bits strike the standard balance between flute length and overall length, making them the go-to choice for general-purpose drilling in metal, wood, plastics, and composite materials. The HSS construction provides the hardness and heat resistance needed for production drilling in shop environments. Machinists, pipefitters, electricians, and plumbers reach for jobber bits when running holes for fasteners, conduit knockouts, pipe penetrations, and mechanical connections.

This drill bit is suited for use in drill presses, hand drills, and portable magnetic drills across residential, commercial, and light industrial job sites. Its 31/64-inch diameter makes it a common choice for pilot holes, clearance holes, and bolt-pattern work where a precise fractional size is required. USA manufacture indicates compliance with domestic tooling standards for consistent geometry and heat treat.

Key Features

• 31/64-inch diameter for precise fractional sizing in metal and general-purpose drilling
• High-speed steel construction resists heat buildup during extended drilling cycles
• Jobber-length geometry balances reach and rigidity for versatile shop and field use
• USA manufactured for consistent point geometry and heat treatment
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed as a standard fractional HSS jobber drill bit compatible with any 3/8-inch or 1/2-inch chuck drill press, hand drill, or portable drill rated for HSS tooling.

Installation Notes

Secure the bit firmly in the chuck and verify runout before drilling. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend tool life and maintain hole quality. Always wear eye protection and secure workpieces properly before operation. Reduce feed pressure as the bit breaks through to prevent grab and bit damage.
