M.a. Ford 20042180 Die Drill Bit 27/64 in Carbide

Product Description

The M.A. FORD 20042180 is a solid carbide die drill bit designed for precision holemaking in demanding industrial and toolroom applications. Built to Series 200 specifications, it features a 27/64 inch (0.4219 inch decimal) diameter, a 135-degree split point for accurate self-centering, and a web-thinned geometry that reduces thrust and improves chip evacuation. The straight-flute design with two flutes makes it well suited for short-chipping materials where a standard spiral flute would pack chips. This bit is sized with a diameter tolerance of +0.0000 to -0.0005 inches, meeting DIN standards for close-tolerance work. Licensed machinists, tool-and-die makers, and precision fabricators are the primary users.

This drill bit is intended for holemaking in cast iron, non-ferrous metals, stainless steel, carbon steel, alloy steel, austenitic stainless steel, high-temperature alloys, titanium, hardened materials, ceramics, and glass. The uncoated solid carbide construction performs across this wide material range where coatings may not be compatible or where re-grinding is anticipated. It is commonly used in die shops, precision machining centers, and fabrication environments that require repeatable hole geometry and tight diameter tolerances.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 135-degree split point promotes self-centering and reduces walking on entry
• Straight-flute geometry designed for short-chipping materials such as cast iron and certain non-ferrous metals
• Web-thinned design lowers cutting thrust and improves chip clearance
• Uncoated finish allows regrinding and suits applications where coatings are incompatible
• Diameter tolerance of +0.0000 to -0.0005 inches supports close-tolerance hole requirements
• Right-hand cutting direction; compatible with standard drill press and machining center setups

Compatibility

Rated for use in cast iron, non-ferrous metal, stainless steel, steel, alloy steel, austenitic stainless steel, high-temperature alloys, titanium, hardened materials, ceramics, and glass per M.A. FORD Series 200 application data. No additional specific machine or spindle compatibility data was provided in the product input.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with carbide tooling. Secure the shank firmly in a collet or drill chuck rated for the 27/64 inch (0.4219 inch) shank diameter before operation. Carbide is brittle - avoid side loading, interrupted cuts without appropriate feed reduction, or dropping the bit. Confirm spindle speed and feed rate are appropriate for the workpiece material and machine rigidity before commencing the cut.
