M.a. Ford. 20405950 Jobber Drill Bit 53 Solid Carbide

Product Description

The M.A. FORD. 20405950 is a solid carbide jobber length drill bit sized at wire gauge number 53, equivalent to 0.0595 inches in diameter. It features a 118-degree faceted drill point and a two-flute spiral configuration with web thinning for improved chip evacuation and reduced thrust. The overall length is 1.5 inches, with a flute length of 0.75 inches and a straight-cylindrical shank. This bit is manufactured to ISO 9001:2015 standards and carries a bright, uncoated finish. It is intended for use by machinists, tool-and-die technicians, and maintenance professionals requiring precision small-diameter drilling in demanding materials.

This drill bit is suited for general-purpose drilling operations in cast iron, non-ferrous metals, stainless steel, and carbon steel. Its solid carbide construction makes it appropriate for applications where high rigidity and wear resistance are required, particularly in short-run and production drilling on machining centers, drill presses, and CNC equipment. The 5xD flute-to-diameter ratio supports adequate chip clearance at this small diameter. Series 204 designates M.A. FORD.s standard jobber length carbide line for this size range.

Compatibility

Designed as a general-purpose OEM-style jobber length drill bit for use in standard straight-shank drill chucks on machining centers, CNC mills, and drill presses compatible with 0.0595-inch shank tooling.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with small-diameter carbide tooling. Secure the straight-cylindrical shank firmly in a properly sized collet or drill chuck before operation. Solid carbide bits are brittle compared to high-speed steel alternatives and are susceptible to breakage if subjected to side loading or interrupted cuts without appropriate feed and speed parameters. Always power down and de-energize the machine spindle before changing tooling.
