M.a. Ford. 20403200A Jobber Drill 67 Solid Carbide Tin

Product Description

The M.A. FORD. 20403200A is a solid carbide jobber-length drill bit in wire size 67 (0.0320 inches diameter), designed for precision drilling in demanding materials. It features a 118-degree four-facet point, a web-thinned tip for reduced thrust and cleaner entry, and a right-hand spiral flute configuration. The ALtima and Titanium Nitride (TiN) dual coating improves surface hardness and extends tool life in abrasive workpiece materials. Overall length is 1.5 inches with a 0.375-inch flute length. This drill is suited for machinists, toolroom technicians, and production drilling applications requiring tight dimensional tolerances in small-diameter work.

This drill is rated for general-purpose use across a range of primary workpiece materials including cast iron, non-ferrous metals, stainless steel, and carbon steel. The straight-cylindrical shank seats directly into standard drill chucks and collets without adapters. The 5xD flute-to-diameter ratio provides adequate chip clearance for the small diameter. Typical applications include precision hole-making in manufacturing, fabrication, and toolroom environments where small wire-gauge holes are required in ferrous and non-ferrous materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 118-degree four-facet point with web thinning for reduced cutting thrust and accurate hole entry
• ALtima and TiN coating for improved surface hardness and extended tool life
• Right-hand spiral flute with regular spiral type for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Diameter tolerance of +0.0000 to -0.0005 inches for consistent, repeatable hole sizing

Compatibility

Designed as a general-purpose replacement or production drill for applications requiring wire size 67 (0.0320 inches) diameter holes. Compatible with workpiece materials coded K, M, N, and P, corresponding to cast iron, non-ferrous metals, stainless steel, and carbon steel. Part of the M.A. FORD. Series 204 jobber drill line.

Installation Notes

This drill is installed and operated by machinists or toolroom professionals using standard drill presses, CNC machining centers, or hand-held power tools equipped with a properly sized chuck or collet. Verify spindle runout is within acceptable limits before use, as small-diameter solid carbide drills are sensitive to lateral loading and vibration. Coolant-through is not supported on this tool; apply external cutting fluid appropriate for the workpiece material when drilling stainless steel or cast iron. Follow machine manufacturer guidelines for RPM and feed rate selection for carbide tooling at this diameter.
