M.a. Ford 22925700 Solid Carbide Jobber Drill Bit Letter F

Product Description

The M.A. FORD 22925700 is a solid carbide jobber-length drill bit sized to Letter F (0.2570 inches) with a 150-degree point angle and a three-flute parabolic flute geometry. It is designed for high-performance drilling in non-ferrous metals, including aluminum, copper, brass, and similar materials. The bright, uncoated carbide substrate delivers thermal stability and edge retention without a coating that could alter tolerances. Overall length is 3.25 inches with a 2-inch flute length, making it suitable for general-purpose hole-making tasks where a jobber-length reach is appropriate. Licensed machinists, tool-and-die technicians, and CNC operators are the primary users of this bit.

This drill bit is built for non-ferrous metal applications in production machining and precision fabrication environments. The parabolic flute profile promotes efficient chip evacuation, which is critical when drilling soft, gummy materials like aluminum that tend to load flutes. With a maximum recommended drilling depth of 1.5 inches, it fits standard jobber-length drilling cycles on CNC machining centers, drill presses, and manual mills. It ships individually and is rated to Series 229 specifications under DIN 6537 L.

Key Features

• Solid carbide construction for rigidity and edge retention in non-ferrous materials
• Letter F diameter — 0.2570 inches — with a diameter tolerance of 0.0003 to 0.0008 inches
• Three-flute parabolic geometry for fast chip evacuation in soft metals
• 150-degree standard point angle with web-thinned, tapered web for reduced thrust at entry
• Straight-cylindrical shank (0.2570 inches) for direct collet or chuck mounting
• Bright uncoated finish; no coating interference with tight-tolerance bores
• Meets DIN 6537 L dimensional standard; manufactured under ISO 9001:2015 certification

Compatibility

Designed for drilling non-ferrous metals (material code N and O) including aluminum, copper, and brass alloys. Fits any standard drill chuck or ER collet system accepting a 0.2570-inch straight-cylindrical shank. Conforms to Series 229 and DIN 6537 L jobber-length specifications.

Installation Notes

This bit is intended for installation in CNC machining centers, drill presses, or manual milling machines by qualified machinists or tooling technicians. Secure the straight shank in a collet or drill chuck rated for the spindle speed appropriate to the workpiece material and diameter before starting the cut. Coolant-through is not supported on this bit; use external flood coolant or misting when drilling deep holes to manage heat and chip load. Inspect the cutting edges before each use — carbide is brittle and should not be used if chipping or cracking is visible on the flutes or point.
