M.a. Ford 20414950 Solid Carbide Jobber Drill Bit

Product Description

The M.A. FORD 20414950 is a solid carbide jobber-length drill bit in wire gauge size No. 25, with a decimal diameter of 0.1495 inches and an overall length of 2.5 inches. The bit features a 118-degree faceted point and a 2-flute regular spiral flute with a web-thinned, tapered web for improved chip evacuation and reduced thrust at entry. Bright uncoated finish maintains a sharp cutting edge without added coating thickness. The straight-cylindrical shank matches the body diameter at 0.1495 inches, making it compatible with standard drill chucks. Diameter tolerance is held to -0.0005 to 0.0000 inches, which is typical for precision boring operations. Licensed machinists, toolmakers, and maintenance technicians install this type of bit in CNC machining centers, drill presses, and hand-held power tools.

This bit is rated as a general-purpose tool suited for cast iron, non-ferrous metals, stainless steel, and carbon and alloy steels. The 5xD flute-to-diameter ratio provides adequate chip clearance for jobber-length drilling depths. It is well suited to production environments where consistent hole quality in metallic workpieces is required, including automotive, aerospace maintenance, and general metalworking applications. The ISO 9001:2015 certification on the Series 204 line indicates that manufacturing processes meet an internationally recognized quality management standard.

Compatibility

Designed for use in standard drill chucks accepting a 0.1495-inch straight-cylindrical shank. Rated for cast iron, non-ferrous metals, stainless steel, and steel workpiece materials per M.A. FORD Series 204 application guidelines.

Installation Notes

Secure the straight-cylindrical shank firmly in a keyed or keyless drill chuck before operation; verify runout with a dial indicator in precision setups. Use appropriate cutting fluid or coolant when drilling stainless steel or hardened alloys to manage heat buildup, even though this bit is not coolant-through. Inspect the cutting edges and point geometry before each use - solid carbide is harder than HSS but more brittle, and chipped edges should be addressed by a qualified tool grinder before reuse. Follow the machine manufacturer and applicable workplace safety standards when setting spindle speed and feed rate for the workpiece material.
