M.a. Ford. 20413600 Jobber Length Drill Bit No. 29

Product Description

The M.A. FORD. 20413600 is a solid carbide jobber length drill bit in wire gauge size No. 29, with a decimal diameter of 0.1360 inches. It features a 118-degree faceted drill point and a regular spiral flute with web thinning for improved chip evacuation and reduced thrust. The overall length is 2.5 inches with a 1.375-inch flute length. The bright, uncoated finish is suitable for general-purpose drilling across a range of metallic workpiece materials. Licensed tradespeople and machinists working in production, maintenance, or fabrication environments will find this drill appropriate for precision hole work in harder and softer metals alike.

This drill bit is designed for use in cast iron, non-ferrous metals, stainless steel, and steel. It is suited for CNC machining centers, drill presses, and hand-held drilling equipment where a straight-cylindrical shank is required. The 5xD flute-to-diameter ratio supports drilling to moderate depth in a single pass. The tapered web configuration and web-thinned geometry help reduce cutting forces in harder materials such as stainless steel and cast iron, making it a practical choice for both job shop and production floor applications.

• Regular spiral flute with tapered web for consistent chip flow in ferrous and non-ferrous materials
• Bright, uncoated finish for compatibility with a wide range of cutting fluids or dry cutting conditions
• Manufactured under ISO 9001:2015 certified quality standards

Compatibility

Designed for general-purpose drilling in cast iron, non-ferrous metal, stainless steel, and steel. Compatible with any drill chuck or collet system accepting a 0.1360-inch straight-cylindrical shank. Part of M.A. FORD. Series 204.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify shank runout and chuck grip are within acceptable limits before beginning a cut, as solid carbide is brittle and susceptible to breakage from lateral loading or vibration. Follow applicable shop safety procedures and machine manufacturer guidelines for speed and feed selection based on workpiece material.
