M.a. Ford 22914400 Carbide Jobber Drill Bit No. 27

Product Description

The M.A. FORD 22914400 is a solid carbide jobber-length drill bit sized to wire gauge No. 27 (0.1440 inches decimal) with a 150-degree point angle and a parabolic flute profile. The bright, uncoated carbide construction delivers the edge retention and rigidity needed for consistent, accurate hole production in non-ferrous materials. Overall length is 2.5 inches with a 1.375-inch flute length, offering the reach required for typical jobber-depth applications. The 3-flute parabolic geometry promotes fast chip evacuation and reduces heat buildup at cutting speeds appropriate for aluminum, brass, copper, and similar non-ferrous workpieces. This bit is intended for use in CNC machining centers, drill presses, and precision hand-held drilling equipment operated by machinists and toolroom technicians.

This drill bit is rated for primary use in non-ferrous metals (material code N, O) and is well suited for production and prototype work where dimensional accuracy is critical. The 0.1440-inch shank diameter matches the cutting diameter, allowing direct chuck or collet mounting without a step-down adapter. The Series 229 designation from M.A. FORD corresponds to a high-performance, short-series carbide drill line conforming to DIN 6537 L dimensional standards. The web-thinned, tapered web design reduces entry thrust force, which benefits thin-wall or precision-tolerance applications.

Key Features

• Solid carbide construction for rigidity and edge retention in non-ferrous materials
• 150-degree point angle with standard point type for accurate self-centering entry
• 3-flute parabolic geometry for aggressive chip evacuation and reduced heat buildup
• Web-thinned, tapered web reduces thrust force at drill entry
• Bright uncoated finish — compatible with cutting fluids without coating-compatibility concerns
• Conforms to DIN 6537 L; manufactured under ISO 9001:2015 certified quality system

Compatibility

Designed for use in CNC machining centers, drill presses, and precision drilling equipment accepting a 0.1440-inch straight-cylindrical shank. Optimized for non-ferrous metal workpiece materials per M.A. FORD Series 229 application guidelines.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician familiar with carbide tooling. Secure the straight-cylindrical shank fully in a collet or drill chuck rated for the intended spindle speed before operation. Carbide tooling is brittle — avoid side-loading, interrupted cuts beyond the tool's rated capacity, or dropping the bit on hard surfaces. Verify spindle runout is within tolerance before use, as excessive runout accelerates premature edge failure on small-diameter carbide drills.
