M.a. Ford 60025003 Countersink 90 Deg 1 Flute Carbide

Product Description

The M.A. FORD 60025003 is a single-flute, solid carbide countersink designed for precise 90-degree countersinking operations in a wide range of materials. Built with a straight-cylindrical shank measuring 1/4 inch in diameter and an overall length of 2 inches, this tool is suited for use in CNC machining centers, drill presses, and hand-held power tools. The bright, uncoated finish keeps the carbide substrate exposed for maximum hardness and heat resistance. With a head diameter of 1/4 inch and a tip diameter of 0.0450 inches, this tool delivers clean, accurately angled seats for flathead fasteners. Machinists, tool-and-die technicians, and fabricators working in job shop and production environments are the primary users.

This countersink is well-suited for applications requiring consistent 90-degree chamfers in ferrous and non-ferrous materials across light manufacturing, aerospace prep work, and general metalworking. The single-flute geometry reduces chatter in interrupted cuts and is particularly effective in softer materials where surface finish is critical. The solid carbide construction supports higher RPM use compared to high-speed steel alternatives, making it a reliable choice where cycle time and repeatability matter.

Key Features

• 90-degree included angle with a 45-degree centerline angle for standard flathead fastener seating
• Single-flute design minimizes chatter and improves surface finish in soft and medium-hardness materials
• Solid carbide construction throughout for extended tool life and compatibility with higher spindle speeds
• 1/4 inch straight-cylindrical shank fits standard collets and drill chucks without adapters
• Bright, uncoated finish maintains dimensional accuracy and works across a broad material range
• No pilot included — works as a standalone countersink for flexible positioning

Compatibility

Compatible material applications include alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel. Designed as a single-end countersink with no pilot, fitting standard 1/4 inch collets and chucks.

Installation Notes

This tool is installed by a machinist or tooling technician into a compatible collet, end mill holder, or drill chuck accepting a 1/4 inch straight shank. Confirm spindle speed and feed rate are appropriate for the workpiece material before engaging the cut — carbide is brittle and susceptible to chipping from shock loads or improper setup. Secure the workpiece fully before operation to prevent tool breakage. Inspect the cutting edge for chipping before each use; a damaged single-flute countersink will produce inconsistent chamfer geometry.
