Eagle Cutting Tool D250-020-I 5/16 Inch Hss Drill Bit

Product Description

The EAGLE CUTTING TOOL D250-020-I is a 5/16 inch high-speed steel (HSS) drill bit built for production and general-purpose drilling applications. The 135-degree split point geometry reduces walking on contact, allowing the bit to self-center without a pilot hole. It is designed for use in hand drills, drill presses, and CNC equipment where consistent hole quality and tool longevity are priorities. Tradespeople working in metal fabrication, HVAC rough-in, electrical rough-in, and plumbing installations rely on this style of bit for boring clean holes through steel, cast iron, and similar ferrous materials.

This drill bit is suited for professional use in light industrial and commercial settings. The Dyno bright ground finish is appropriate for dry or lightly lubricated drilling in ferrous and non-ferrous metals, as well as hard plastics. It is a practical choice for HVAC technicians, electricians, and plumbers who need a reliable general-purpose HSS bit for repetitive field or shop drilling tasks.

Key Features

• 5/16 inch diameter for standard bolt-clearance and conduit-knockout applications
• 135-degree split point reduces thrust and eliminates the need for a center punch on flat stock
• High-speed steel construction retains hardness at elevated cutting temperatures
• Dyno bright ground finish for consistent dimensional accuracy and smooth chip evacuation
• Minimum order quantity of 1 allows single-unit procurement

Compatibility

Designed as a standard 5/16 inch HSS drill bit compatible with any 3/8 inch or larger keyed or keyless drill chuck accepting straight-shank bits in hand drills, drill presses, and CNC drilling equipment.

Installation Notes

This bit is installed by licensed tradespeople and qualified machinists using standard drill equipment. Ensure the drill is fully stopped and unpowered before inserting or removing the bit from the chuck. Apply cutting fluid or lubricant when drilling ferrous metals to extend tool life and improve hole finish. Follow applicable workplace safety standards and use appropriate eye protection during all drilling operations.
