M.a. Ford. 20406350 Jobber Drill Bit Size 52 Solid Carbide

Product Description

The M.A. FORD. 20406350 is a solid carbide jobber length drill bit designed for precision drilling in a wide range of metalworking applications. Ground to a No. 52 wire gauge diameter of 0.0635 inches, this bit features a 118-degree faceted point and a web-thinned, tapered web for cleaner entry and reduced thrust. The bright uncoated finish makes it well suited for use without coolant. With an overall length of 1.5 inches and a flute length of 0.75 inches, it is built for short-reach, high-accuracy work. Machinists and tool and die professionals are the primary installers of this type of tooling.

This drill bit is rated for general-purpose use in cast iron, non-ferrous metals, stainless steel, and steel. The two-flute spiral design with a regular spiral type provides efficient chip evacuation in these materials. It is a straight-cylindrical shank bit compatible with standard collets and drill chucks. The 5xD flute-to-diameter ratio supports controlled chip removal in shorter hole depths typical of this bit size. It is manufactured under ISO 9001:2015 certified quality standards, making it appropriate for production and maintenance environments where dimensional consistency is required.

Compatibility

Designed for use in cast iron, non-ferrous metals, stainless steel, and steel. Fits standard straight-cylindrical shank collets and drill chucks accepting a 0.0635-inch shank diameter.

Installation Notes

This tooling is installed and operated by machinists, tool and die technicians, and maintenance professionals using CNC machining centers, drill presses, or hand drills with compatible chucks. Ensure the machine spindle and chuck are fully stopped and de-energized before changing tooling. Verify chuck or collet runout is within acceptable limits before use, as excessive runout at this diameter will accelerate wear and reduce hole accuracy. Follow applicable shop safety protocols and machine manufacturer guidelines for speed and feed selection.
