M.a. Ford 79200001 Countersink 60 Degree 6 Flute Hss

Product Description

The M.A. FORD 79200001 is a 6-flute, single-end countersink made from high-speed steel (HSS) and designed for right-hand cutting. With a 60-degree included angle and a 2 inch head diameter, it handles chamfering, countersinking, and deburring operations across a wide range of workpiece materials. The straight cylindrical shank measures 3/4 inch in diameter, and the tool runs 2-1/4 inches overall. The bright, uncoated finish is standard for general-purpose HSS tooling. This tool is installed and used by machinists, tool-and-die technicians, and maintenance professionals working in production or fabrication environments.

This countersink is suited for both manual and CNC machine tool setups where a clean chamfer or deburring pass is required. It does not include a pilot, making it appropriate for applications where pilot-free entry is preferred. The 60-degree angle and 6-flute geometry produce smooth, chatter-resistant cuts in a broad range of materials including mild steel, stainless steel, aluminum, brass, cast iron, and plastics. The 3/4-inch straight shank is compatible with standard drill press chucks, milling machine collets, and CNC tool holders sized to accept that shank diameter.

Key Features

• 60-degree included angle (30-degree centerline angle) for standard chamfer and countersink geometry
• 6-flute design reduces chatter and produces a smoother finished surface compared to fewer-flute versions
• High-speed steel construction provides toughness across a wide range of workpiece materials
• Bright/uncoated finish suits general-purpose use without coating-related material restrictions
• Pilot-free single-end design for flexible application across varying hole diameters
• Straight cylindrical 3/4-inch shank for compatibility with standard machine tool holders

Compatibility

Designed for use in drill presses, milling machines, and CNC machining centers equipped with tool holders accepting a 3/4-inch straight cylindrical shank. Suitable for chamfering, countersinking, and deburring operations in alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel workpieces.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool from the holder. Secure the straight shank firmly in a properly sized collet or chuck to prevent runout. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.
