M.a. Ford. 20060940 Solid Carbide Die Drill Bit 39/64 in

Product Description

The M.A. FORD. 20060940 is a solid carbide die drill bit designed for precision holemaking in demanding materials. It features a straight-flute geometry with a 135-degree split point and web-thinned construction, which reduces thrust and improves centering at entry. The cutting diameter is 0.6094 inches (39/64 inches) with a tight diameter tolerance of +0.0000 to -0.0005 inches. The overall length is 3.5 inches with a 1.25-inch flute length. This bit is built to Series 200 DIN standards and is intended for use by machinists and toolroom professionals working in production or die-shop environments.

This drill bit is suited for holemaking operations in cast iron, steel, alloy steel, stainless steel, austenitic stainless steel, titanium, high temperature alloys, and hardened materials, as well as non-ferrous metals, ceramics, and glass. It is a right-hand cutting tool appropriate for vertical mills, drill presses, and CNC machining centers where rigid setups and controlled feed rates are maintained. The uncoated carbide construction makes it a practical choice for shops that regrind their own tooling.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 135-degree split point reduces thrust and improves self-centering without a pilot
• Web-thinned geometry lowers cutting resistance and extends tool life
• Straight-flute design suited for short-chipping materials such as cast iron and hardened steels
• Tight diameter tolerance of +0.0000 to -0.0005 inches for close-tolerance hole requirements
• Right-hand cutting direction with two flutes; no coolant-through passages

Compatibility

Designed for use in standard drill chucks and collet holders accepting a 0.6094-inch (39/64-inch) shank diameter. Suitable for CNC machining centers, knee mills, and drill presses where solid carbide tooling is appropriate for the workpiece material and machine rigidity.

Installation Notes

Secure the shank fully in a rigid collet or drill chuck rated for carbide tooling before use. Carbide is brittle and susceptible to breakage under side loading or interrupted cuts without adequate machine rigidity. Power down and lock out the spindle before changing or inspecting the bit. Follow the machine tool manufacturer and applicable shop safety guidelines for speeds and feeds appropriate to the workpiece material.
