M.a. Ford 20007850 Solid Carbide Die Drill Bit 0.0785 in

Product Description

The M.A. FORD 20007850 is a solid carbide, straight-flute die drill bit designed for precision holemaking in demanding materials. Built to Series 200 specifications, it measures 0.0785 inches in diameter (Wire Size 47) with a 135-degree split point and web-thinned geometry that reduces entry force and improves chip evacuation. The uncoated carbide construction delivers rigidity and heat resistance in applications where high-speed steel tooling falls short. With a 3/8-inch flute length and 1-1/2-inch overall length, this bit is sized for toolroom, die, and mold work where tight tolerances and short, controlled cuts are the standard. Right-hand cutting direction. Two flutes. Diameter tolerance is +0.0000 to -0.0005 inches, confirming this is a precision-ground tool intended for close-tolerance work.

This drill bit is rated for use in cast iron, non-ferrous metals, stainless steel, and steel as primary workpiece materials. Secondary material compatibility extends to alloy steel, austenitic stainless steel, hardened materials, high-temperature alloys, titanium, ceramic, and glass. The short flute and rigid carbide body make it well-suited for die and mold shops, toolrooms, and any application requiring accurate, repeatable hole placement in hard or abrasive materials. It conforms to DIN standards. Installed by machinists and toolroom technicians on drill presses, CNC machining centers, and precision benchtop equipment.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 135-degree split point with web-thinned geometry reduces thrust force and self-centers on entry
• Wire Size 47 (0.0785 inches) diameter with tight tolerance of +0.0000 to -0.0005 inches
• Straight-flute design suited to through and blind holes in brittle or short-chipping materials
• Uncoated finish maintains sharpness for regrinding and works without coating-related adhesion concerns
• Conforms to DIN standards; right-hand cut, two flutes

Compatibility

Rated for holemaking in cast iron, non-ferrous metal, stainless steel, and steel. Secondary compatible materials include alloy steel, austenitic stainless steel, ceramic, glass, hardened materials, high-temperature alloys, stainless steel, and titanium. Classified under M.A. FORD Series 200.

Installation Notes

Installation and use by qualified machinists or toolroom technicians is recommended. Secure the shank fully in a collet or drill chuck rated for the 0.0785-inch shank diameter before operation. Verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before engaging the cut. Do not apply side loads to the flute length, as carbide tooling is brittle and will fracture under lateral stress.
