M.a. Ford 60050004C Countersink 100 Deg 1 Flute Carbide

Product Description

The M.A. FORD 60050004C is a single-flute solid carbide countersink designed for precision chamfering, countersinking, and deburring across a wide range of materials. It features a 100-degree included angle and a straight-cylindrical shank measuring 1/4 inch in diameter. The overall length is 2.375 inches, and the head diameter is 0.5 inches. The cutting range spans from 1/16 inch minimum to 29/64 inch maximum cutting diameter. The carbide cutting geometry delivers clean entry angles on both ferrous and non-ferrous substrates. Licensed machinists and tooling specialists typically select this countersink for high-precision hole prep in production and maintenance environments.

This countersink is suited for use on alloy steel, mild steel, stainless steel, cast iron, high-nickel steel, high-tensile steel, Monel, aluminum, brass, magnesium, magnesium alloy, and plastic. The right-hand cutting direction and single-flute design make it effective for controlled material removal in both manual and CNC-driven applications. It is appropriate for light chamfering of fastener seats, deburring drilled holes, and preparing countersunk screw recesses in both production shop and field maintenance scenarios.

Key Features

• 100-degree included angle for standard and wide-angle countersink profiles
• Single-flute geometry for smooth, chatter-resistant cutting action
• Solid carbide construction for extended tool life on hard and abrasive materials
• Straight-cylindrical 1/4 inch shank compatible with standard collets and chucks
• Cutting range from 1/16 inch to 29/64 inch suits a broad range of fastener sizes
• Right-hand cutting direction for use with conventional CNC and drill press setups

Compatibility

Designed as an OEM-style replacement or direct procurement countersink for standard 1/4 inch straight-shank toolholders, collets, and drill chucks used in CNC machining centers, drill presses, and hand-held drilling equipment.

Installation Notes

This countersink is installed by machinists and tooling technicians using a standard collet, end mill holder, or drill chuck sized for a 1/4 inch straight shank. Ensure the machine spindle is fully stopped and locked out before changing or seating the tool. Verify shank seating depth and runout before beginning a cut to avoid premature tool wear. Carbide tooling is brittle - avoid side-loading or impact contact during setup and storage.
