M.a. Ford. 22918110 Carbide Jobber Drill Bit 4.6 Mm

Product Description

The M.A. FORD. 22918110 is a solid carbide jobber-length drill bit designed for high-performance drilling in non-ferrous metals and similar materials. Built to DIN 6537 L standards, this bit features a 150-degree drill point angle and a three-flute parabolic design that promotes efficient chip evacuation and reduced cutting resistance. The overall length is 74 mm (approximately 2.91 inches) with a 36 mm (approximately 1.42 inches) flute length. The 6 mm (approximately 0.24 inches) straight-cylindrical shank provides secure clamping in standard drill chucks or collet holders. It is web-thinned at the tip for easier entry and reduced thrust force. This bit is appropriate for machine shop technicians, metalworking tradespeople, and precision maintenance professionals.

The 22918110 is suited for production and maintenance drilling operations in non-ferrous metal workpieces, including aluminum, brass, copper, and similar materials designated under material code N and O. The 5xD flute-to-diameter ratio supports deeper drilling passes while maintaining chip flow. Maximum drilling depth is 29 mm (approximately 1.14 inches). The bright uncoated carbide surface is well-suited to applications where coating interaction with the workpiece material is a concern. This bit is intended for use in CNC machining centers, drill presses, and other rigid, controlled-feed setups.

Key Features

• Solid carbide construction to DIN 6537 L specification for consistent dimensional accuracy
• 150-degree drill point angle optimized for entry into non-ferrous metals
• Three-flute parabolic design for fast chip removal and reduced heat buildup
• Web-thinned tip with tapered web configuration reduces axial thrust at entry
• Straight-cylindrical 6 mm shank fits standard collet chucks without adapter
• Diameter tolerance of 0.0002 to 0.0006 inches (0.004 to 0.016 mm) for close-tolerance hole requirements

Compatibility

Designed as a Series 229 high-performance carbide drill bit for use in rigid machine setups. Compatible with standard 6 mm collet holders and drill chucks. Intended for non-ferrous metal workpieces per DIN material codes N and O. No coolant-through capability; use external coolant or cutting fluid as required by the application.

Installation Notes

This bit is intended for installation by qualified machine operators or tooling technicians in controlled-feed drilling applications. Secure the straight-cylindrical shank firmly in a collet or drill chuck rated for the shank diameter before operation. Always power down and lock out the machine spindle before changing tooling. Do not use in hand-held drilling applications; rigid machine setups are required to maintain tolerance and prevent premature tool failure.
