M.a. Ford 20625000 Carbide Screw Machine Drill Bit 0.25in

Product Description

The M.A. FORD 20625000 is a solid carbide screw machine length drill bit sized at 0.25 inches (Letter E) with a 118-degree faceted point angle. Built to Series 206 specifications, it features a web-thinned, parallel-web construction that reduces thrust and improves chip evacuation at the cutting tip. The right-hand spiral flute and straight-cylindrical shank are standard for use in CNC machining centers, drill presses, and screw machine applications. With a bright/uncoated finish and a diameter tolerance held to +0.0000 to -0.0005 inches, this bit is suited for precision hole-making across a range of metalworking applications.

This drill bit is designed for short-length, high-accuracy drilling in production and job-shop environments. It is rated for use in cast iron, non-ferrous metals, stainless steel, and steel. The 3xD flute-to-diameter ratio and 1-inch flute length make it well-suited for through-hole and blind-hole work in moderate-depth applications where rigidity and concentricity are critical. Machinists, tool-and-die shops, and metalworking professionals working with tight-tolerance bores will find this bit appropriate for their operations.

Key Features

• Bright/uncoated finish suited for dry cutting or use with cutting fluids
• Diameter tolerance of +0.0000 to -0.0005 inches for precision hole sizing
• Straight-cylindrical shank fits standard drill chucks and collet holders

Compatibility

Rated for primary workpiece materials including cast iron, non-ferrous metal, stainless steel, and steel. Designed for use in screw machine, CNC, and drill press setups accepting a 0.25-inch straight-cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or metalworking professionals. Secure the shank fully in the collet or chuck before operation and verify runout before cutting. Always follow machine manufacturer guidelines for spindle speed and feed rate based on workpiece material. Wear appropriate PPE including eye protection when operating drilling equipment.
