M.a. Ford. 61075006 Countersink 120 Degree Hss

Product Description

The M.A. FORD. 61075006 is a single-flute, high-speed steel countersink designed for chamfering, countersinking, and deburring operations across a wide range of materials. It features a 120-degree included angle with a 3/4-inch head diameter and a 1/2-inch straight cylindrical shank. Overall length is 2.75 inches. The bright, uncoated finish makes it well-suited for general-purpose cutting where coating buildup is not a concern. This tool is handled by machinists, tool and die workers, and fabrication professionals working in production or maintenance environments.

This countersink is built for use on a broad spectrum of materials including mild steel, alloy steel, stainless steel, cast iron, aluminum, brass, magnesium, magnesium alloy, high-tensile steel, high-nickel steel, Monel, and plastic. It fits standard drill press chucks, CNC machining centers, and hand-held power tools with a compatible 1/2-inch chuck. The single-flute design reduces chatter on entry, making it practical for hand-held and low-rigidity setups. No pilot is included, and the end type is single.

Key Features

• 120-degree included angle with a 60-degree centerline angle for standard countersink profiles
• 3/4-inch head diameter with a 0.12-inch tip/nose diameter
• 1/2-inch straight cylindrical shank for broad chuck compatibility
• Single-flute geometry reduces chatter in hand-held and low-rigidity applications
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Bright/uncoated finish suitable for general-purpose chamfering and deburring

Compatibility

Suitable for use on alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel workpieces. Fits any drill press, machining center, or power tool accepting a 1/2-inch straight cylindrical shank.

Installation Notes

Always secure the workpiece firmly before operation and ensure the spindle is fully stopped before changing or adjusting the tool. Verify chuck grip on the straight cylindrical shank before engaging the cut. Machinists should follow applicable shop safety standards and machine manufacturer guidelines when operating countersinks at speed.
