M.a. Ford. 79T100003 Countersink 90 Degree 6 Flute Hss Tin

Product Description

The M.A. FORD. 79T100003 is a 6-flute, 90-degree countersink designed for precision chamfering and countersinking in a wide range of metal and non-metal materials. Manufactured from high-speed steel with a titanium nitride (TiN) finish, it delivers extended tool life and reduced friction during cutting. The straight-cylindrical shank measures 0.5 inches in diameter, and the overall length is 2.75 inches. Cutting range spans from 0.25 inches minimum to 1 inch maximum diameter. This tool is used by machinists, fabricators, and maintenance technicians working with manual or CNC drilling equipment.

This countersink is suited for single-end countersinking operations on a broad material spectrum including alloy steel, mild steel, stainless steel, cast iron, high-tensile steel, high-nickel steel, Monel, aluminum, brass, magnesium, magnesium alloy, and plastic. It is appropriate for both production and maintenance environments where consistent 90-degree chamfer geometry is required. The right-hand cutting direction is standard for conventional drill press and CNC machining center use.

Key Features

• 90-degree included angle for standard countersinking and chamfering applications
• 6-flute design provides smooth cutting action and improved surface finish
• High-speed steel construction offers durability across a wide material range
• TiN coating reduces friction and extends tool life compared to uncoated HSS
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Single-end tool with right-hand cutting direction for conventional machine setups

Compatibility

Designed as an OEM-style single-end countersink for use in standard drill press, mill, or CNC machining applications requiring a 90-degree chamfer on a 0.5-inch straight-cylindrical shank.

Installation Notes

This tool is installed by machinists and fabricators using standard drill chucks or collet holders accepting a 0.5-inch straight shank. Ensure the machine spindle is fully stopped and secured before mounting or removing the tool. Use appropriate cutting fluid or lubricant for ferrous materials to maintain edge life. Follow shop safety protocols and machine manufacturer guidelines for spindle speed selection based on workpiece material and cut diameter.
