M.a. Ford. 20608200 Carbide Screw Machine Drill Bit 0.082in

Product Description

The M.A. FORD. 20608200 is a solid carbide screw machine length drill bit designed for precision drilling in demanding industrial and machining applications. Built to Series 206 specifications, it features a 0.082-inch diameter (Wire Size 45), a 118-degree faceted point angle, and a web-thinned parallel web configuration that reduces entry force and improves chip clearance. The bright/uncoated finish suits applications where coating buildup or heat transfer is not a primary concern. This bit is suited for use by machinists, tool-and-die specialists, and production drilling operations requiring tight-tolerance hole placement.

This drill bit is built for short-length, high-rigidity drilling in cast iron, non-ferrous metals, stainless steel, and steel. The screw machine (stub) length body provides increased rigidity over jobber-length bits, making it a strong choice for CNC machining centers, manual mills, drill presses, and screw machine setups where deflection control and hole accuracy are critical. The 3xD flute-to-diameter ratio supports effective chip evacuation in short-depth holes.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 0.082-inch diameter (Wire Size 45) with diameter tolerance of +0.0000 to -0.0005 inches for precise hole sizing
• 118-degree faceted point with web-thinning for reduced thrust and cleaner entry
• Right-hand cut, 2-flute spiral design promotes efficient chip removal
• Straight-cylindrical shank fits standard drill chucks without adapters
• Bright/uncoated finish compatible with a wide range of cutting fluids and materials

Compatibility

Rated for primary workpiece materials including cast iron, non-ferrous metal, stainless steel, and steel. Fits any standard drill chuck accepting a 0.082-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with carbide tooling. Secure the shank fully in the chuck and verify runout before beginning a drilling cycle, as carbide is brittle and sensitive to lateral loading. Always use appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain surface finish. Do not use this bit for interrupted cuts or angled entry without engineering review, as carbide is susceptible to chipping under impact or off-axis forces.
