M.a. Ford. 20403800A Jobber Drill Bit 0.038 in Solid Carbide

Product Description

The M.A. FORD. 20403800A is a jobber-length drill bit built for precision drilling in demanding materials. Manufactured from solid carbide and coated with ALtima TiN, this bit is designed for extended tool life in cast iron, stainless steel, general steel, and non-ferrous metals. The 118-degree four-facet point provides accurate self-centering starts and reduced thrust. At 0.0380 inches in diameter with an overall length of 1.5 inches, it fits within the Series 204 lineup for small-diameter, high-performance drilling applications. A right-hand spiral flute design with web thinning promotes chip evacuation and reduces cutting resistance in tight-tolerance holes.

This drill bit is suited for production and maintenance drilling in metalworking environments, including fabrication shops, machine shops, and industrial maintenance settings. Its two-flute regular spiral geometry and straight cylindrical shank work with standard drill chucks and collet-style toolholders. The 5xD flute-to-diameter ratio supports chip clearance in deeper holes relative to diameter. It is appropriate for use in CNC drilling centers, drill presses, and hand-held power tools where small-diameter precision holes are required in steel, stainless steel, cast iron, and non-ferrous workpieces.

Key Features

• Solid carbide construction with ALtima TiN coating for extended wear resistance
• 118-degree four-facet point for accurate starts and reduced walking on hard materials
• Web-thinned design reduces cutting thrust and improves chip evacuation
• Right-hand cut, regular spiral flute optimized for steel, stainless steel, cast iron, and non-ferrous metals
• Straight cylindrical shank compatible with standard drill chucks and collet holders
• Manufactured under ISO 9001:2015 certified processes

Compatibility

Designed for use with workpiece materials including cast iron, non-ferrous metals, stainless steel, and steel (Primary Workpiece Material Codes: K, M, N, P). Compatible with standard straight-shank drill chucks and collet toolholding systems. Suitable for drill presses, CNC machining centers, and hand-held power tools accepting 0.0380-inch shank diameter tooling.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with small-diameter carbide tooling. Secure the shank fully in the chuck or collet before operation to prevent runout or breakage. Carbide tooling is brittle and should not be used in applications with excessive vibration or interrupted cuts without verifying suitability. Inspect the cutting edge and coating condition before each use, as solid carbide bits at this diameter are sensitive to chipping from side loading or improper feed rates.
