M.a. Ford 20062500 Carbide Die Drill Bit 5/8 in

Product Description

The M.A. FORD 20062500 is a solid carbide, straight-flute die drill bit designed for precision holemaking in demanding industrial and toolroom applications. It measures 0.6250 inches in diameter with an overall length of 3.5000 inches and a flute length of 1.2500 inches. The 135-degree split point reduces thrust and self-centers on entry, making it well-suited for hard, abrasive, or difficult-to-machine workpiece materials. The web-thinned geometry further reduces cutting forces. The uncoated carbide construction provides consistent dimensional accuracy with a diameter tolerance of +0.0000 to -0.0005 inches. This bit is installed by machinists, tool and die makers, and skilled trades professionals working with precision drilling equipment.

The 20062500 is built for holemaking in cast iron, steel, alloy steel, stainless steel, austenitic stainless steel, titanium, high temperature alloys, hardened materials, non-ferrous metals, ceramic, and glass. Its solid carbide body handles the heat and abrasion generated when drilling these materials at sustained feeds and speeds. The straight-flute design is particularly effective in brittle materials where chip control and lateral stability are critical. The 2-flute configuration provides clearance for chip evacuation in short-hole applications. This bit conforms to DIN standards, making it compatible with DIN-compliant toolholding systems.

Key Features

• Solid carbide construction for high rigidity and wear resistance in hard and abrasive materials
• 135-degree split point with web thinning reduces entry thrust and improves self-centering
• Straight-flute design optimized for drilling brittle materials including cast iron, ceramic, and glass
• Uncoated finish with tight diameter tolerance of +0.0000 to -0.0005 inches for precise hole sizing
• Right-hand cutting direction with 2-flute geometry for efficient chip clearance in short holes
• Conforms to DIN standards for compatibility with standard DIN toolholding

Compatibility

The 20062500 is rated for primary workpiece materials including cast iron, non-ferrous metal, stainless steel, and steel, with secondary suitability for alloy steel, austenitic stainless steel, ceramic, glass, hardened materials, high temperature alloys, stainless steel, and titanium. Coolant-through is not supported on this bit.

Installation Notes

This drill bit is intended for use by machinists and tool and die professionals operating drill presses, milling machines, or CNC machining centers with appropriate spindle speeds for carbide tooling. Always secure the workpiece firmly before drilling and confirm the toolholder shank bore matches the 0.6250-inch shank diameter. Carbide is brittle - avoid lateral loading, interrupted cuts without proper setup, or dropping the bit on hard surfaces. Verify spindle runout is within acceptable limits before use to protect the cutting edge and maintain hole tolerances.
