M.a. Ford 20404000 Jobber Drill Bit No. 60 Solid Carbide

Product Description

The M.A. FORD 20404000 is a jobber-length drill bit designed for precision small-hole drilling in demanding materials. Ground from solid carbide, this bit carries a wire gauge No. 60 diameter of 0.0400 inches and an overall length of 1.5 inches. The 118-degree faceted point and web-thinned geometry reduce entry force and improve centering accuracy. A regular spiral flute with a 5xD flute-to-diameter ratio evacuates chips efficiently from shallow holes. The bright, uncoated finish is suited for dry or mist-cooled applications. This bit is intended for installation and machining professionals working in tight-tolerance applications where consistent hole diameter and clean entry are required.

Designed for general-purpose drilling across a range of materials including cast iron, steel, stainless steel, and non-ferrous metals, the 20404000 fits standard jobber-length drill applications in production machining, maintenance, and toolroom environments. The straight cylindrical shank seats directly in standard drill chucks, collets, and CNC tool holders without adapters. Its compact 1.5-inch overall length suits benchtop drill presses, hand drills, and machining centers where clearance is limited.

Key Features

• Solid carbide construction for superior wear resistance in abrasive and hard materials
• Wire gauge No. 60 diameter (0.0400 inches) with a tight diameter tolerance of -0.0005 to 0.0000 inches
• 118-degree faceted drill point with web thinning for reduced thrust and accurate self-starting
• Regular spiral flute, 5xD ratio, for reliable chip evacuation in shallow drilling
• Straight cylindrical shank compatible with standard drill chucks and collets
• Manufactured under ISO 9001:2015 certified quality standards

Compatibility

Designed as a general-purpose jobber-length drill bit suitable for use in standard drill chucks, CNC machining centers, and benchtop drill presses that accept straight cylindrical shanks at 0.0400 inches diameter. Rated for cast iron, steel, stainless steel, and non-ferrous metal workpieces.

Installation Notes

Machining professionals and toolroom technicians should ensure the workpiece is securely fixtured and the spindle is at a full stop before changing or seating this bit. Verify chuck or collet runout before use, as excess runout will accelerate wear on small-diameter carbide tooling. Carbide bits are brittle compared to high-speed steel; avoid side loading or using as a reamer. Follow applicable shop safety standards for eye protection and chip containment when drilling ferrous materials.
