M.a. Ford 20028120 Carbide Die Drill Bit 9/32 in

Product Description

The M.A. FORD 20028120 is a solid carbide die drill bit designed for precision holemaking in demanding industrial and toolroom applications. Built to Series 200 standards, it features a 9/32 inch (0.2813 inch) diameter with a 135-degree split point for fast engagement and reduced walking on entry. The straight-flute geometry and web-thinned construction lower thrust requirements and improve chip evacuation. With a 2-flute, right-hand cutting configuration and an uncoated carbide blank, this bit is suited for machinists, tool and die makers, and production operators working with tight-tolerance bores.

This drill bit is engineered for holemaking in a wide range of workpiece materials including cast iron, steel, alloy steel, stainless steel, austenitic stainless steel, titanium, high-temperature alloys, hardened materials, non-ferrous metals, ceramic, and glass. The 3/4 inch flute length suits shallow-to-moderate depth holes in die work, mold plates, and precision fixtures. The 2-1/2 inch overall length fits standard drill chucks and collet holders used in CNC machining centers, drill presses, and manual mills.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 135-degree split point reduces thrust and minimizes drill walk on entry
• Web-thinned design improves chip flow and lowers cutting forces
• Straight-flute geometry suits die work and short-chip materials such as cast iron and hardened steel
• Uncoated finish maintains sharp edge geometry and allows easy regrinding
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style precision drill for use in standard drill chucks, ER collet systems, and hydraulic toolholders accepting a 9/32 inch straight shank. Conforms to DIN standards for drill geometry and tolerances.

Installation Notes

Installation and use should be performed by qualified machinists or tool and die professionals familiar with carbide tooling. Secure the shank fully within the collet or chuck before operation and verify runout is within acceptable limits, as carbide is brittle and sensitive to lateral loading. Power down the spindle completely before changing or inspecting tooling. Do not use this bit in applications requiring coolant-through delivery, as this tool does not support internal coolant flow.
