M.a. Ford. 20012850 Solid Carbide Die Drill Bit 0.1285 in

Product Description

The M.A. FORD. 20012850 is a solid carbide, straight-flute die drill bit designed for precision holemaking in demanding materials. Built to Series 200 standards, it features a 135-degree split point and web-thinned geometry that reduces thrust and improves centering at entry. The cutting diameter is 0.1285 inches (Wire Size 30), with a flute length of 0.625 inches and an overall length of 2 inches. Right-hand cutting direction and an uncoated carbide body make it suitable for high-speed, tight-tolerance work in tool and die, mold, and precision machining operations. Machinists and toolmakers are the primary installers.

This drill bit is built for cutting cast iron, non-ferrous metals, stainless steel, alloy steel, austenitic stainless steel, high-temperature alloys, titanium, hardened materials, ceramics, and glass. Its compact flute length and short overall length make it well suited for restricted-clearance setups, die cavities, and small-part fixturing on CNC machining centers, drill presses, and manual knee mills. The 135-degree split point and web-thinned tip reduce walking and cutting forces when entering hard or abrasive workpiece materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 135-degree split point reduces thrust and improves hole entry accuracy
• Web-thinned geometry lowers cutting forces and extends tool life
• Straight-flute design suited for short-chipping materials such as cast iron and non-ferrous metals
• Diameter tolerance of +0.0000 to -0.0005 inches supports close-tolerance hole requirements
• Conforms to DIN standards for consistent dimensional accuracy

Compatibility

Designed for use in precision holemaking applications across cast iron, steel, stainless steel, non-ferrous metals, high-temperature alloys, titanium, hardened materials, ceramics, and glass. Suitable for use in CNC machining centers and manual machine tools accepting a 0.1285-inch round shank.

Installation Notes

Installation is performed by machinists or toolmakers using standard drill chuck or collet toolholding systems. Verify runout on the spindle and toolholder before use, as carbide is sensitive to lateral loading. Secure the workpiece rigidly to prevent movement during cutting. Follow machine manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.
