M.a. Ford 20404690 Carbide Drill Bit 3/64 Inch 118 Degree

Product Description

The M.A. FORD 20404690 is a solid carbide jobber length drill bit designed for precision drilling in demanding materials. At 3/64 inch (0.0469 inch decimal) diameter and a 118-degree faceted point angle, it delivers clean entry and controlled chip evacuation across a range of workpiece materials. The bright, uncoated finish suits applications where surface interaction with coatings is a concern. With a regular spiral flute and web-thinned, tapered web configuration, this bit minimizes thrust load at breakthrough. It is sized for use in CNC machining centers, drill presses, and precision hand-held equipment where tight diameter tolerances are required.

This drill bit is rated for general-purpose use in cast iron, non-ferrous metals, stainless steel, and steel. It follows a 5xD flute-to-diameter ratio, making it suitable for through-hole and moderate-depth drilling operations in production and job-shop environments. Machinists, tool-and-die technicians, and precision fabricators working on tight-tolerance assemblies will find the straight-cylindrical shank compatible with standard drill chucks and collet systems. The Series 204 designation places it within M.A. FORD's general-purpose solid carbide line.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 118-degree faceted point angle for self-centering entry and reduced walking
• Web-thinned, tapered web reduces cutting thrust and improves chip flow
• Regular spiral, 2-flute design provides efficient chip evacuation
• Bright uncoated finish suitable for non-ferrous metals and general-purpose drilling
• Manufactured under ISO 9001:2015 certified quality standards

Compatibility

Designed for use in cast iron, non-ferrous metals, stainless steel, and steel workpieces. The straight-cylindrical shank fits standard drill chucks and collet holders sized for 3/64 inch shanks. Rated for general-purpose drilling applications across workpiece material codes K, M, N, and P per ISO classification.

Installation Notes

This bit is intended for use by machinists and precision fabricators in machine tool environments. Secure the shank fully in a properly sized chuck or collet before operation and verify runout before drilling. Solid carbide is brittle compared to high-speed steel; avoid side loading, interrupted cuts without adequate support, or dropping the bit on hard surfaces. Follow machine manufacturer feed and speed recommendations for the specific workpiece material.
