M.a. Ford. 20446880 Carbide Jobber Drill Bit 15/32 in

Product Description

The M.A. FORD. 20446880 is a solid carbide jobber length drill bit with a 15/32-inch (0.4688 inch) diameter and a 118-degree faceted point angle. Designed for general-purpose drilling, it features a bright uncoated finish, a regular spiral flute, and a straight-cylindrical shank. The two-flute design with web-thinned, tapered web geometry reduces entry resistance and improves chip evacuation. Overall length is 4-3/4 inches with a 3-inch flute length. Right-hand cutting direction. Installed by machinists and metalworking tradespeople working with ferrous and non-ferrous materials in production or maintenance environments.

This drill bit is rated for use in cast iron, non-ferrous metals, stainless steel, and steel. It carries a 5xD flute-by-diameter ratio suited for moderate-depth holes in a wide range of metal workpieces. The Series 204 designation indicates a general-purpose solid carbide platform, appropriate for both CNC and manual drilling operations where consistent hole tolerance is required. Diameter tolerance is -0.0005 to 0.0000 inches, making it suitable for close-tolerance applications.

Compatibility

Designed as a general-purpose solid carbide jobber length drill bit for use in cast iron, non-ferrous metal, stainless steel, and steel workpieces. Compatible with standard drill chucks and collets accepting a 15/32-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or metalworking professionals familiar with rotating cutting tool safety. Secure the shank fully in the chuck or collet before operation and verify runout before drilling. Use appropriate cutting fluid or coolant based on workpiece material and machine specifications. Inspect the cutting edge for wear or chipping before each use; carbide tooling is brittle and should not be subjected to side-loading or impacts.
