M.a. Ford. 20073440 Carbide Die Drill Bit 47/64 in

Product Description

The M.A. FORD. 20073440 is a solid carbide, straight-flute die drill bit designed for high-precision holemaking in demanding materials. Built to Series 200 standards and compliant with DIN specifications, it features a 135-degree split point and web-thinned geometry that reduces entry force and improves centering accuracy. The bit carries a diameter tolerance of +0.0000 to -0.0005 inches, making it appropriate for tight-tolerance die and mold work. With a 4-inch overall length and 1.5-inch flute length, this uncoated carbide bit is suited for machinists and toolroom technicians working in production or job-shop environments.

This drill bit is intended for holemaking in a wide range of workpiece materials, including cast iron, non-ferrous metals, stainless steel, alloy steel, austenitic stainless steel, hardened materials, high-temperature alloys, titanium, ceramic, and glass. Its straight-flute configuration and right-hand cutting direction are well suited to controlled drilling operations in die sets, fixtures, and precision components where chip control and hole quality are critical priorities.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 135-degree split point reduces walking and lowers thrust force at entry
• Web-thinned geometry improves chip clearance and cutting efficiency
• Straight-flute design supports controlled drilling in brittle materials such as ceramic and glass
• Diameter tolerance of +0.0000 to -0.0005 inches meets tight-fit holemaking requirements
• DIN-compliant Series 200 construction for consistent dimensional standards

Compatibility

Designed for use in CNC machining centers, drill presses, and manual mills where a straight-shank carbide die drill is required for holemaking in ferrous, non-ferrous, stainless, hardened, and exotic alloy workpieces.

Installation Notes

This bit should be installed by a qualified machinist familiar with carbide tooling requirements. Secure the shank firmly in an appropriate collet or drill chuck rated for the 0.7344-inch shank diameter before starting the spindle. Solid carbide tooling is brittle and susceptible to breakage under side-loading or interrupted cuts - avoid lateral force during operation. Verify spindle speed and feed rate against material-specific cutting data before use; running carbide tooling dry or at incorrect parameters will cause premature failure.
