M.a. Ford. 22921650 Solid Carbide Jobber Drill Bit 5.5mm

Product Description

The M.A. FORD. 22921650 is a solid carbide jobber-length drill bit with a 5.5 mm (0.2165 inch) diameter, designed for high-performance drilling in non-ferrous metals. Built to DIN 6537L standards, it features a 150-degree drill point angle with web thinning for reduced thrust and cleaner entry. The three-flute parabolic spiral geometry improves chip evacuation and allows faster feed rates compared to standard two-flute geometry. Right-hand cutting direction and a straight-cylindrical shank make it compatible with standard drill chucks and CNC toolholders. This bit is suited for machinists, tool-and-die professionals, and precision fabricators working with aluminum, brass, copper, and similar non-ferrous workpiece materials.

The 22921650 is intended for use in non-ferrous metal applications where surface finish, hole accuracy, and chip control are critical. It is sized within the 5.00 to 6.00 mm range per DIN 6537L and carries an 82 mm overall length with a 44 mm flute length, supporting a maximum drilling depth of 35 mm. The 6.00 mm straight-cylindrical shank fits standard precision chucks and collet systems used in CNC machining centers and manual drill presses. A bright uncoated finish maintains dimensional integrity and suits applications where coatings may react with workpiece materials or cutting fluids.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous metal drilling
• 150-degree point angle with web thinning reduces entry thrust and improves centering
• Three-flute parabolic geometry enhances chip evacuation and supports higher feed rates
• Bright uncoated finish suitable for non-ferrous and reactive workpiece materials
• DIN 6537L specification with diameter tolerance of 0.004 to 0.016 mm for precision hole sizing
• 5xD flute-to-diameter ratio supports drilling depths up to 35 mm

Compatibility

Designed for use with non-ferrous metals including aluminum, brass, and copper, per primary workpiece material designation N and O. Fits standard straight-cylindrical chuck and collet systems accepting a 6.00 mm shank diameter. Conforms to DIN 6537L specification within the 5.00 to 6.00 mm diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom professionals familiar with carbide cutting tool handling. Carbide is brittle and should not be dropped or used in interrupted cuts without evaluating tool path carefully. Ensure the spindle and chuck are properly centered and clamping force is adequate for the 6.00 mm shank before beginning any drilling operation. Always verify workpiece material compatibility before selecting feeds and speeds.
