M.a. Ford. 20443750 Solid Carbide Jobber Drill Bit 7/16 in

Product Description

The M.A. FORD. 20443750 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials. Built to Series 204 specifications, it features a 118-degree faceted point, a web-thinned and tapered web configuration, and a regular spiral flute for efficient chip evacuation. The straight-cylindrical shank measures 7/16 inches in diameter, matching the cutting diameter for straightforward chuck mounting. At 4.5 inches overall length with a 2.875-inch flute, this bit delivers the reach and cutting depth expected in a standard jobber-length tool. Bright uncoated carbide construction is suited for applications where coating adhesion or heat buildup is a concern.

This drill bit is rated for general-purpose drilling in cast iron, non-ferrous metals, stainless steel, and steel. It is appropriate for use in machine shop environments, fabrication, and maintenance applications where a reliable carbide bit is needed across a range of workpiece materials. The 5xD flute-to-diameter ratio supports stable chip removal in both manual and CNC-fed drilling setups. Right-hand cut configuration is standard for conventional drill press, lathe turret, and machining center use.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 118-degree faceted point with web thinning for reduced thrust and improved centering
• Spiral flute with regular helix for consistent chip evacuation in a variety of metals
• Bright uncoated finish - no coating buildup concerns in sensitive or non-ferrous workpieces
• 7/16-inch straight-cylindrical shank fits standard drill chucks without adapters
• ISO 9001:2015 certified manufacturing for dimensional consistency and quality assurance

Compatibility

Designed for use in cast iron, non-ferrous metals, stainless steel, and steel workpieces. Compatible with standard drill chucks, drill presses, lathes, and CNC machining centers accepting a 7/16-inch straight-cylindrical shank. Suitable for general-purpose drilling within the 0.4000 to 0.5000 inch diameter range category.

Installation Notes

This bit should be installed and operated by a qualified machinist or tooling professional. Ensure the machine spindle and chuck are fully stopped and de-energized before inserting or removing the bit. Secure the shank firmly in the chuck to the full depth of the jaws to prevent slippage during drilling. Solid carbide tooling is brittle - avoid side-loading, interrupted cuts without appropriate feed rates, or dropping the tool on hard surfaces.
