Eagle Cutting Tool D250-028-I 7/16 Hss Drill Bit 135 Split Point

Product Description

The EAGLE CUTTING TOOL D250-028-I is a 7/16 inch high-speed steel (HSS) drill bit engineered for demanding drilling applications in metal, wood, and composite materials. Built with a 135-degree split point geometry, this bit self-centers on contact, reducing walking on hard surfaces and minimizing the need for a center punch. The Dyno grind finishing process provides consistent cutting edge geometry across the flutes, supporting cleaner hole entry and reduced heat buildup during extended use. Trades professionals working in fabrication, mechanical, electrical, and general industrial environments will find this bit suited to heavy-duty production and service work.

This drill bit is intended for use in handheld drills, drill presses, and magnetic base drills where a 7/16 inch diameter hole is required. It performs well on mild steel, cast iron, aluminum, and similar materials common in HVAC, plumbing, and electrical rough-in work. The HSS construction handles moderate heat and provides acceptable tool life under typical job site or shop conditions without requiring coolant in most applications.

Key Features

• 7/16 inch diameter for standard bolt clearance and conduit knockout applications
• 135-degree split point self-centers and reduces bit walking on smooth or hard surfaces
• High-speed steel (HSS) construction withstands moderate drilling heat
• Dyno grind process delivers consistent flute geometry and cutting edge uniformity
• Suitable for use in handheld drills and stationary drill presses

Compatibility

Designed as a general-purpose HSS twist drill bit compatible with standard 3-jaw drill chucks accepting round shanks in the 7/16 inch size range. Suitable for use across trade and light industrial drilling applications.

Installation Notes

Secure the bit firmly in the chuck and verify it runs true before drilling. Use appropriate cutting speed for the material being drilled — slower speeds are recommended for harder metals to preserve cutting edge life. Wear appropriate eye protection when drilling metal or composite materials. Inspect the cutting edges before each use and retire the bit if chipping or excessive wear is observed.
