M.a. Ford. 20408200 Solid Carbide Jobber Drill Bit 0.082

Product Description

The M.A. FORD. 20408200 is a solid carbide jobber length drill bit engineered for high-precision drilling in demanding materials. It carries a wire gauge size of No. 45 with a decimal diameter of 0.0820 inches and an overall length of 1.75 inches. The 118-degree faceted point geometry delivers clean entry and accurate positioning without walking. A web-thinned, tapered web design reduces thrust force at the tip. With a 5xD flute-to-diameter ratio and regular spiral fluting, the bit evacuates chips efficiently while maintaining rigidity. Licensed machinists, tool-and-die techs, and metalworking professionals install and use this bit in CNC and manual drilling operations where tight tolerances are required.

This bit is suited for drilling cast iron, non-ferrous metals, stainless steel, and steel. Its general-purpose grade makes it a versatile choice for production and maintenance environments where a single bit must handle multiple material types. The straight-cylindrical shank fits standard drill chucks without modification. The bright uncoated finish is appropriate for use without coolant-through capability, making it compatible with conventional drill press and hand-drill setups where external coolant or dry cutting is the norm. It is part of M.A. FORD. Series 204, a jobber-length solid carbide line intended for precision metalworking.

Key Features

• 118-degree faceted drill point for accurate self-starting entry
• Web-thinned tapered web reduces cutting thrust and improves hole quality
• Regular spiral flute with 5xD ratio provides effective chip evacuation
• Right-hand cut, straight-cylindrical shank fits standard chucks directly
• Manufactured under ISO 9001:2015 certified quality standards

Compatibility

Designed for general-purpose drilling in cast iron, non-ferrous metal, stainless steel, and steel workpieces. Fits any standard drill chuck accepting a 0.0820-inch straight-cylindrical shank.

Installation Notes

This bit is installed and used by machinists, tool-and-die technicians, and metalworking professionals. Secure the straight-cylindrical shank firmly in a calibrated drill chuck before operation, and verify chuck runout is within acceptable limits to protect the small-diameter carbide shank from breakage. Carbide is brittle compared to high-speed steel; avoid side-loading, interrupted cuts without proper feed rate control, and over-tightening that can crack the shank. When replacing or handling the bit, use appropriate tooling to avoid contact damage to the cutting edges.
