Eagle Cutting Tool D250-221-D Hss Drill Bit 135SP

Product Description

The EAGLE CUTTING TOOL D250-221-D is a U-letter size high-speed steel (HSS) jobber-length drill bit ground to a 135-degree split point. The 135-degree split point geometry reduces walking on contact, allowing the bit to start cutting immediately without a center punch on most materials. The Dyno-Bright finish indicates a polished flute surface that helps reduce friction and chip buildup during drilling. This bit is manufactured in the USA and is suited for use in hand drills, drill presses, and CNC equipment across metalworking, mechanical, and fabrication trades.

The D250-221-D is designed for drilling into steel, aluminum, cast iron, copper, brass, and similar ferrous and non-ferrous metals. U-letter size bits are commonly used in precision machining and fabrication where fractional and numbered drill sizes do not hit the required hole diameter. The 135-degree split point makes this bit especially effective in harder materials where self-centering and reduced thrust are priorities. It is a standard choice for machine shops, maintenance technicians, and pipefitters working to specific hole tolerances.

Key Features

• U-letter size diameter for precision hole sizing beyond standard fractional increments
• 135-degree split point reduces bit walk and lowers required feed pressure
• High-speed steel (HSS) construction provides heat and wear resistance during metal drilling
• Dyno-Bright polished finish reduces friction and aids chip evacuation from flutes
• Manufactured in the USA to jobber-length standards

Compatibility

Designed as an OEM-style replacement or direct substitution for U-letter size HSS jobber drill bits used in standard three-jaw drill chucks and collet systems compatible with jobber-length shanks.

Installation Notes

This bit is installed by trade professionals including machinists, maintenance mechanics, and pipefitters using standard drill chucks or collet holders. Secure the shank fully in the chuck before operation and verify chuck key is removed before powering the spindle. Use appropriate cutting fluid or coolant when drilling harder metals to extend bit life. Power down all equipment completely before changing or inspecting bits.
