M.a. Ford 22912000 Carbide Drill Bit No. 31 Wire Size

Product Description

The M.A. FORD 22912000 is a solid carbide jobber length drill bit designed for high-performance drilling in non-ferrous metals and similar materials. It measures 0.1200 inches in diameter (wire size No. 31) with an overall length of 2.25 inches and a flute length of 1.25 inches. The 150-degree drill point angle and parabolic flute geometry promote efficient chip evacuation and reduced thrust during drilling. Web thinning further reduces cutting resistance at the entry point. The straight-cylindrical shank seats securely in standard drill chucks. This bit is intended for use by machinists, tool-and-die professionals, and precision fabricators working with tight-tolerance applications.

The 22912000 is suited for drilling non-ferrous metals including aluminum, brass, copper, and plastics. The parabolic flute design with a 5xD flute-to-diameter ratio supports deeper drilling relative to bit diameter. The maximum drilling depth is 0.9375 inches (15/16 inch). The bright, uncoated finish is appropriate for non-ferrous applications where coating compatibility or heat management are not primary concerns. This bit is well matched to CNC drilling centers, drill presses, and handheld precision equipment used in production and maintenance machining environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous applications
• 150-degree drill point angle reduces thrust and improves entry geometry
• Parabolic flute design with 5xD ratio supports efficient chip evacuation
• Web-thinned, tapered web configuration reduces cutting resistance at the drill tip
• Bright, uncoated finish suited for non-ferrous metals and plastics
• Manufactured to DIN 6537 L standards; produced under ISO 9001:2015 certified quality management

Compatibility

Designed for use in drilling non-ferrous metals (material code N and O) as an OEM-style Series 229 jobber length drill bit. Specific compatible machine models were not identified in the available product data; confirm chuck compatibility with the 0.1200-inch straight-cylindrical shank before installation.

Installation Notes

Installation is performed by machinists and precision fabricators using standard drill chucks or collet systems. Ensure the machine spindle is fully stopped and the tool holder is secure before inserting or removing the bit. Verify that the chuck capacity accommodates a 0.1200-inch shank diameter. Do not exceed the maximum drilling depth of 0.9375 inches without retracting to clear chips, as parabolic flute geometry aids but does not eliminate chip packing in blind holes.
