M.a. Ford. 22915750 Carbide Jobber Drill Bit 4 Mm

Product Description

The M.A. FORD. 22915750 is a solid carbide jobber length drill bit engineered for high-performance drilling in non-ferrous materials. It features a 4 mm diameter, a 150-degree split point, and a three-flute parabolic flute design that promotes fast chip evacuation and reduced cutting resistance. The bright uncoated finish is suited to applications where coating adhesion is not required. With an overall length of 74 mm and a flute length of 36 mm, this bit follows the DIN 6537L standard. It is installed and used by machinists, tool-and-die technicians, and precision fabricators working with CNC or manual drilling equipment.

This drill bit is designed for use in non-ferrous metals such as aluminum, copper, brass, and similar materials designated under material group N and O. The 5xD flute-to-diameter ratio and web-thinned tapered web reduce thrust and improve hole quality in these materials. The straight cylindrical shank diameter of 6 mm fits standard drill chucks and collet holders. This bit is appropriate for production drilling environments and precision shop work where dimensional accuracy and consistent hole finish are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous drilling
• 150-degree standard point angle reduces thrust and improves self-centering
• Three-flute parabolic design accelerates chip evacuation and reduces heat buildup
• Web-thinned tapered web lowers cutting resistance and extends tool life
• Bright uncoated finish suitable for non-ferrous material groups N and O
• Meets DIN 6537L specification and manufactured under ISO 9001:2015 certified processes

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers, drill presses, and manual machines accepting a 6 mm straight cylindrical shank. Suited for primary workpiece materials coded N and O per DIN classification, covering non-ferrous metals.

Installation Notes

This bit is installed by machinists and tooling technicians. Ensure the machine spindle is fully stopped and the chuck or collet is disengaged before inserting or removing the bit. Verify the shank is fully seated and the collet or chuck is torqued to machine specifications before operation. Do not exceed the maximum drilling depth of 29 mm per pass without retracting to clear chips.
