M.a. Ford 20424200A Letter C Solid Carbide Jobber Drill

Product Description

The M.A. FORD 20424200A is a solid carbide jobber-length drill bit in Letter C size (0.2420 inches), designed for high-performance drilling in demanding production and maintenance environments. It features a 118-degree four-facet point ground with web thinning to reduce thrust and improve center starting accuracy. The ALtima plus Titanium Nitride (TiN) dual coating increases surface hardness and heat resistance, extending tool life in abrasive materials. At 3.25 inches overall length with a 2-inch spiral flute, this right-hand cut drill is suited for licensed machinists, tool-and-die shops, and field service technicians working with precision tolerances.

This drill is built for general-purpose metal cutting across a range of workpiece materials including steel, stainless steel, cast iron, and non-ferrous metals. It fits standard straight-shank drill chucks found on CNC machining centers, drill presses, and hand-held power tools. The Series 204 designation identifies it within M.A. FORD's jobber drill line, covering the 0.2000 to 0.2500 inch diameter range. The 5xD flute-to-diameter ratio provides adequate chip clearance without sacrificing rigidity in short-reach applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 118-degree four-facet point with web thinning reduces walking and entry thrust
• ALtima plus TiN dual coating improves heat resistance and extends tool life
• Regular spiral flute with right-hand cut for standard drilling operations
• Diameter tolerance of +0.0000 to -0.0005 inches for close-tolerance hole production
• ISO 9001:2015 certified manufacturing for consistent dimensional accuracy

Compatibility

Designed as an OEM-style replacement or direct upgrade for Letter C (0.2420 inch) jobber drills used in general-purpose drilling of steel, stainless steel, cast iron, and non-ferrous metals. Fits any standard straight-cylindrical shank chuck accepting a 0.2420-inch shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with cutting tool safety. Secure the shank fully in the drill chuck before operation and verify chuck key is removed prior to powering the machine. Do not exceed the recommended feed and speed parameters for the workpiece material. Solid carbide tooling is brittle and should not be used in setups with excessive runout or lateral load.
