M.a. Ford. 79125001 Countersink 60 Degree 6 Flute Hss

Product Description

The M.A. FORD. 79125001 is a 6-flute, high-speed steel countersink designed for chamfering, countersinking, and deburring operations in metal fabrication and machining environments. It features a 60-degree included angle and a 1.25-inch head diameter, making it well-suited for creating clean, precise conical seats in a wide range of materials. The straight-cylindrical shank measures 0.5 inches in diameter, and the tool has an overall length of 2.25 inches. The bright, uncoated finish is standard for HSS tooling used across general-purpose shop applications. This tool is installed and operated by machinists, tool-and-die workers, and maintenance technicians.

This countersink is appropriate for use in manual drill presses, CNC machining centers, and hand-held drill applications where a consistent 60-degree chamfer or countersink profile is required. Its 6-flute geometry produces a smoother cut and reduces chatter compared to single- or 3-flute designs. The tip nose diameter measures 0.37 inches. The tool is suited for both production runs and single-piece maintenance work across a broad range of material types.

Key Features

• 60-degree included angle produces standard countersink profiles for fastener seating
• 6-flute design reduces chatter and delivers a smoother finished surface
• High-speed steel construction provides durability across a wide range of workpiece materials
• Straight-cylindrical 0.5-inch shank fits standard drill chucks and collet holders
• Bright uncoated finish; no coating buildup to affect dimensional accuracy
• Single-end design with no pilot; suitable for general chamfering and deburring tasks

Compatibility

Compatible with alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel workpieces as specified by the manufacturer.

Installation Notes

Installation is performed by machinists or maintenance technicians using a drill press, milling machine, or hand drill with an appropriate chuck or collet accepting a 0.5-inch straight shank. Power down and de-energize the machine before mounting or removing the tool. Secure the shank fully in the chuck or collet to the manufacturer-recommended engagement depth before operation. Use appropriate cutting fluid or lubrication when working with ferrous metals to extend tool life and improve finish quality.
