M.a. Ford 20404100 Jobber Drill Bit 59 Solid Carbide

Product Description

The M.A. FORD 20404100 is a jobber-length drill bit designed for precision drilling in demanding materials. Built from solid carbide with a bright, uncoated finish, this bit cuts with a right-hand spiral flute and features a 118-degree faceted point with web thinning for clean entry and reduced thrust. Wire size 59 corresponds to a decimal diameter of 0.0410 inches. The straight-cylindrical shank and overall length of 1.5 inches make it compatible with standard drill chucks and collets. This bit is part of M.A. FORD Series 204, a general-purpose line suited for machine shop, maintenance, and production drilling applications.

This drill bit is intended for use in CNC machining centers, drill presses, and handheld pneumatic or electric drills where tight tolerances are required. Its solid carbide construction and tapered web configuration make it well-suited for drilling cast iron, stainless steel, non-ferrous metals, and steel. The regular spiral flute geometry and 5xD flute-to-diameter ratio support chip evacuation in through-hole and blind-hole applications. Machinists, toolroom technicians, and precision fabricators are the primary users of this bit size range.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 118-degree faceted point with web thinning for reduced entry thrust
• Right-hand cut with regular spiral flute and tapered web configuration
• Bright, uncoated finish suitable for general-purpose dry or wet cutting
• Straight-cylindrical shank at 0.0410 inches for standard chuck compatibility
• ISO 9001:2015 certified manufacturing for consistent dimensional accuracy

Compatibility

Designed as a general-purpose replacement or stock drill bit for applications requiring wire size 59 (0.0410 inches) in Series 204 jobber-length tooling. Suitable for use in standard drill chucks and collets accepting straight-cylindrical shanks of 0.0410 inches.

Installation Notes

This bit is installed by machinists or toolroom technicians in standard drill chucks or collets. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck or collet runout is within tolerance before drilling, as runout accelerates wear on small-diameter carbide bits. Carbide is brittle - avoid side-loading or using in applications with significant vibration without appropriate fixturing.
