M.a. Ford. 20415400 Carbide Jobber Drill Bit No. 23

Product Description

The M.A. FORD. 20415400 is a solid carbide jobber length drill bit sized to wire gauge No. 23, with a decimal diameter of 0.154 inches. It features a 118-degree faceted point and a spiral flute with web-thinned, tapered web geometry for clean entry and reduced thrust. The straight-cylindrical shank has a 0.154-inch diameter matching the cutting diameter. Overall length is 2.5 inches with a flute length of 1.375 inches, yielding a 5xD flute-to-diameter ratio. The bright, uncoated carbide finish suits general-purpose drilling applications across a range of workpiece materials. Right-hand cut with two flutes and a regular spiral type. Machinists and tooling technicians specify this bit for production and maintenance drilling tasks.

This drill bit is designed for general-purpose drilling in cast iron, non-ferrous metals, stainless steel, and steel. The solid carbide construction provides the rigidity and wear resistance needed when drilling harder materials where high-speed steel tooling underperforms. The No. 23 wire size and compact jobber length make it well suited for precision hole work in machine shops, maintenance facilities, and manufacturing environments. Coolant-through capability is not present, so adequate surface or flood cooling should be planned when drilling stainless steel or other work-hardening alloys at higher feed rates.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 118-degree faceted drill point with web-thinned, tapered web for reduced thrust and cleaner entry
• Wire gauge No. 23 cutting diameter of 0.154 inches with diameter tolerance of -0.0005 to 0.0000 inches
• 2-flute regular spiral design with 1.375-inch flute length and 5xD flute-to-diameter ratio
• Bright uncoated finish suitable for general-purpose use across multiple workpiece material groups
• ISO 9001:2015 certified manufacturing for consistent dimensional quality

Compatibility

Designed as an OEM-style general-purpose solid carbide jobber drill for use in standard straight-shank drill chucks and collet holders accepting a 0.154-inch shank diameter. Rated for cast iron, non-ferrous metals, stainless steel, and steel workpiece materials per primary workpiece material codes K, M, N, and P.

Installation Notes

Installation of this drill bit is performed by machinists and tooling technicians using a standard drill chuck or ER collet system rated for the 0.154-inch straight-cylindrical shank. Ensure the machine spindle is fully stopped and secured before changing tooling. Verify runout after seating to maintain the tight diameter tolerance of -0.0005 to 0.0000 inches. When drilling stainless steel or cast iron, apply appropriate cutting fluid or coolant to manage heat since this bit does not feature coolant-through capability.
