M.a. Ford. 20039060 Solid Carbide Die Drill Bit 25/64 in

Product Description

The M.A. FORD. 20039060 is a solid carbide die drill bit engineered for precision holemaking in demanding materials. It features a 25/64 inch (0.3906 inch) cutting diameter, a 135-degree split point for accurate positioning and reduced walking, and a straight-flute design suited for through-hole drilling in hard or abrasive workpieces. The uncoated carbide construction provides rigidity and thermal resistance in applications where coatings may not be compatible with the workpiece or cutting fluid chemistry. This bit is used by machinists, tool-and-die makers, and skilled fabricators working in production and job-shop environments.

This drill bit is designed for holemaking in a broad range of metallic and hard non-metallic materials, including cast iron, steel, alloy steel, stainless steel, austenitic stainless steel, titanium, high-temperature alloys, hardened materials, ceramic, and glass. It belongs to the M.A. FORD. Series 200 and conforms to DIN standards. With a 1 inch flute length, 1-3/4 inch shank length, and 2-3/4 inch overall length, it fits standard drill chucks and collet systems used in CNC machining centers, drill presses, and manual mills.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 135-degree split point reduces thrust force and eliminates center-punch requirement on most materials
• Web-thinned geometry improves chip evacuation and reduces heat buildup at the cutting edge
• Straight-flute design suited for short-hole drilling and materials that produce small or powdery chips
• Right-hand cutting direction, two flutes, uncoated finish compatible with a wide range of cutting fluids
• Diameter tolerance of +0.0000 to -0.0005 inches ensures close-tolerance hole fits

Compatibility

Designed as an OEM-style Series 200 die drill bit conforming to DIN standards. Suitable for use in CNC machining centers, drill presses, and manual milling machines with collet or drill chuck toolholding systems that accept a 25/64 inch straight shank. Rated for primary workpiece materials including cast iron, non-ferrous metal, stainless steel, and steel, with secondary applicability to alloy steel, austenitic stainless steel, ceramic, glass, hardened materials, high-temperature alloys, and titanium.

Installation Notes

Installation and use should be performed by qualified machinists or tool-and-die professionals familiar with carbide tooling. Secure the shank fully in a collet or drill chuck rated for the spindle speed required by the workpiece material and diameter. Carbide is brittle - avoid side-loading, interrupted cuts without proper feed adjustment, and contact with hard fixtures that can chip the cutting edge. Verify spindle runout before use, as excessive runout will shorten carbide tool life significantly.
