M.a. Ford 20619900 Carbide Screw Machine Drill Bit 0.199in

Product Description

The M.A. FORD 20619900 is a solid carbide screw machine length drill bit with a 0.199 inch (No. 8 wire) diameter and a 118-degree faceted point angle. Designed for short-length, high-rigidity drilling applications, it features a regular spiral flute, a straight-cylindrical shank, and a web-thinned parallel web configuration. The bright uncoated finish makes it suitable for a range of metalworking operations where coating buildup is not desired. With a 2-flute right-hand cut design and a flute-to-diameter ratio of 3xD, it provides reliable chip evacuation in production drilling environments.

This drill bit is built for use on cast iron, non-ferrous metals, stainless steel, and steel. Its screw machine (short) length format gives it added stiffness compared to jobber-length bits, making it well suited for drill press, CNC, and turret lathe work where reduced deflection and hole accuracy are priorities. It fits applications in manufacturing, fabrication, and maintenance shops requiring precise small-diameter drilling.

Key Features

• Solid carbide construction for hardness and wear resistance in metalworking applications
• 0.199 inch diameter with diameter tolerance of +0.0000 to -0.0005 inches for close-tolerance holes
• 118-degree faceted point with web thinning for reduced thrust and faster entry
• Right-hand cut, 2-flute regular spiral for efficient chip removal
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Short screw machine length (2.25 inches overall) for improved rigidity and reduced runout

Compatibility

Designed as a Series 206 screw machine length carbide drill bit suitable for drilling cast iron, non-ferrous metal, stainless steel, and steel workpieces. Fits standard chucks and collets accepting a 0.199 inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or tool-and-die professionals familiar with carbide tooling. Secure the shank fully in a collet or drill chuck before operation and verify runout before committing to production drilling. Solid carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts without proper feed management, or dropping the tool. Follow machine manufacturer guidelines for spindle speed and feed rate based on workpiece material.
