Eagle Cutting Tool D250-020-D 5/16 Hss Drill Bit 135 Split Point

Product Description

The EAGLE CUTTING TOOL D250-020-D is a 5/16 inch high-speed steel (HSS) drill bit built for demanding metal fabrication and mechanical work. Featuring a 135-degree split point geometry, it starts on contact without a center punch, reducing walking on hard or slick surfaces. Manufactured in the USA, this bit is suited for drilling ferrous and non-ferrous metals, plastics, and composite materials. The Dyno BG grind profile promotes efficient chip evacuation and reduces heat buildup during extended use, making it a reliable choice for production drilling or field service work.

This drill bit is appropriate for use in hand-held electric drills, drill presses, and magnetic base drills in both shop and field environments. Electricians, pipefitters, HVAC technicians, plumbers, and general mechanical contractors reach for HSS split-point bits when drilling steel enclosures, strut channel, pipe flanges, junction boxes, and structural steel. The 5/16 inch diameter fits standard 3/8 inch and 1/2 inch chucks without a reducer.

Key Features

• 135-degree split point tip eliminates center-punch requirement and reduces bit walk on contact
• High-speed steel (HSS) construction handles heat generated in continuous metal drilling
• Dyno BG grind promotes fast chip clearing and extended cutting edge life
• USA manufactured to consistent dimensional tolerances
• 5/16 inch diameter fits 3/8 inch and 1/2 inch chucks directly

Compatibility

Designed as an OEM-style replacement or direct-use HSS drill bit suitable for standard 3/8 inch and 1/2 inch keyed or keyless drill chucks used in portable and stationary drilling equipment.

Installation Notes

HSS drill bits should be installed by qualified tradespeople following standard shop and jobsite safety practices. Secure the workpiece fully before drilling and verify chuck tightness before engaging the drill. Use appropriate cutting fluid when drilling hard steel to extend bit life and reduce heat. Inspect the cutting edge before each use and replace bits that show chipping, dullness, or deformation to maintain hole quality and prevent breakage.
