M.a. Ford. 22404920A Jobber Drill Bit 1.25mm Carbide

Product Description

The M.A. FORD. 22404920A is a jobber-length drill bit engineered for precision drilling in demanding trade and industrial applications. Built from solid carbide and finished with an ALtima titanium nitride coating, this bit delivers extended tool life and thermal resistance at the cutting edge. It features a 1.25 mm diameter, a 118-degree faceted point angle, and a web-thinned tip geometry that reduces entry force and improves chip evacuation. The right-hand spiral flute configuration follows a regular helix pattern. Overall length is 38 mm (1.496 inches) with a flute length of 16 mm (0.630 inches). Machinists, tool-and-die technicians, and precision fabricators install this bit in CNC machining centers, drill presses, and hand-held precision drills.

This bit is suited for drilling cast iron, non-ferrous metals, stainless steel, and carbon steel in both production and repair environments. The 5xD flute-to-diameter ratio supports deep-hole drilling relative to diameter for this size class. The straight cylindrical shank with a 1.25 mm shank diameter fits standard collet chucks and precision drill chucks without adaptation. It conforms to DIN 338 specification for jobber-length drills, making it a direct fit in metric tooling setups across manufacturing, maintenance, and fabrication shops.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• ALtima titanium nitride coating reduces friction and extends cutting edge life
• 118-degree faceted point with web thinning for reduced thrust and clean entry
• Right-hand cut, 2-flute regular spiral design for efficient chip removal
• Straight cylindrical shank compatible with standard collet and drill chuck systems
• Conforms to DIN 338 and manufactured under ISO 9001:2015 certified processes

Compatibility

Designed as a DIN 338 jobber-length replacement drill bit for use in CNC machining centers, drill presses, and precision hand tools equipped with collet or drill chucks accepting a 1.25 mm straight cylindrical shank. Suitable for workpiece materials coded K (cast iron), M (stainless steel), N (non-ferrous metals), and P (steel) per ISO material classification.

Installation Notes

Installation and tool changes should be performed by qualified machinists or tooling technicians with the machine powered down and energy isolated per lockout/tagout procedures. Ensure the collet or chuck is clean and properly torqued to the manufacturer specification for the holding device before operation. Do not exceed the recommended feed rate or spindle speed for the workpiece material, as solid carbide tooling is brittle and susceptible to fracture under side-loading or impact. Inspect the cutting edge for chipping before each use.
