M.a. Ford. 22917720 Carbide Jobber Drill Bit 4.5 Mm

Product Description

The M.A. FORD. 22917720 is a solid carbide jobber-length drill bit engineered for high-performance drilling in non-ferrous metals and similar materials. It measures 4.5 mm (0.1772 inches) in diameter with an overall length of 74 mm (2.91 inches) and a flute length of 36 mm (1.42 inches). The 150-degree drill point angle and web-thinned tip reduce entry force and improve centering accuracy. Three parabolic flutes promote efficient chip evacuation, making this bit well suited for production drilling environments where cycle time and hole quality matter. The bright, uncoated carbide surface is appropriate for the non-ferrous work materials this tool targets.

This drill bit is designed for drilling non-ferrous metals such as aluminum, copper, brass, and similar materials coded N and O under standard workpiece material classifications. It is a right-hand-cut tool with a straight-cylindrical shank measuring 6 mm (0.236 inches) in diameter, compatible with standard drill chucks and collet systems. The 5xD flute-to-diameter ratio and parabolic flute geometry support deeper drilling passes with reduced chip packing. Maximum drilling depth is rated at 29 mm (1.14 inches). This tool is used in machine shops, manufacturing lines, and precision fabrication settings where carbide tooling is specified over high-speed steel.

Key Features

• Solid carbide construction for extended tool life in non-ferrous metal drilling
• 150-degree drill point angle with web-thinned tip for reduced entry force and accurate centering
• Three parabolic flutes for efficient chip evacuation and reduced heat buildup
• Straight-cylindrical shank (6 mm diameter) for compatibility with standard chucks and collet holders
• Diameter tolerance held to 0.004 to 0.016 mm for consistent hole sizing
• Meets DIN 6537 L specification and produced under ISO 9001:2015 certified conditions

Compatibility

Designed for use in CNC machining centers, drill presses, and other machine tool spindles accepting a 6 mm straight-cylindrical shank. Intended for drilling non-ferrous metals as classified under primary workpiece material codes N and O per standard tooling classification.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or tooling technicians familiar with carbide tooling practices. Ensure the spindle and chuck or collet are clean and properly torqued before seating the shank. Carbide is brittle — avoid side loading, interrupted cuts without proper setup, or using this bit in handheld drill applications where runout cannot be controlled. Always verify spindle speed and feed rate recommendations from a machining reference appropriate to the workpiece material before cutting.
