M.a. Ford 20414400 Solid Carbide Jobber Drill Bit No 27

Product Description

The M.A. FORD 20414400 is a solid carbide jobber-length drill bit in wire size No. 27, with a decimal diameter of 0.1440 inches and a 118-degree faceted point angle. Designed for general-purpose drilling in ferrous and non-ferrous materials, this bit uses a regular spiral flute and a web-thinned, tapered web geometry to reduce thrust and improve chip evacuation. The straight-cylindrical shank accepts standard drill chucks without modification. At 2.5 inches overall length with a 1.375-inch flute length, it fits benchtop drill presses, CNC machining centers, and handheld power tools used in production and maintenance environments. Installation is performed by machinists and metalworking professionals.

This bit is suited for drilling cast iron, non-ferrous metals, stainless steel, and carbon steel in both production and job-shop settings. The solid carbide construction provides the rigidity and wear resistance needed when working with abrasive or work-hardening materials where high-speed steel tooling underperforms. The bright, uncoated finish makes it a straightforward choice for general-purpose applications where a specialized coating is not required. It ships in single-piece packaging, making it practical for individual replacement or small-lot tooling orders.

Key Features

• Solid carbide construction for rigidity and wear resistance in abrasive workpiece materials
• No. 27 wire size, 0.1440-inch decimal diameter with a tight tolerance of -0.0005 to 0.0000 inches
• 118-degree faceted point with web-thinned, tapered web to lower entry thrust
• Regular spiral flute, right-hand cut, 5xD flute-to-diameter ratio for effective chip clearance
• Straight-cylindrical shank, 0.1440-inch shank diameter for standard chuck compatibility
• ISO 9001:2015 certified manufacturing for consistent dimensional quality

Compatibility

Designed as a general-purpose jobber-length drill bit suitable for use in standard drill chucks on drill presses, CNC machining centers, and handheld power tools. Intended for workpiece materials including cast iron, non-ferrous metals, stainless steel, and steel, corresponding to material codes K, M, N, and P.

Installation Notes

Installation is performed by machinists or qualified metalworking personnel. Secure the straight-cylindrical shank firmly in a properly sized drill chuck before operation. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit. Do not exceed the speed and feed parameters appropriate for solid carbide tooling in the target workpiece material, as carbide is brittle and susceptible to breakage from side loading or interrupted cuts without adequate setup rigidity.
