M.a. Ford. 78037504 Countersink 100 Deg 6 Flute 3/8 in

Product Description

The M.A. FORD. 78037504 is a solid carbide countersink designed for precision chamfering, countersinking, and deburring across a wide range of materials. It features a 100-degree included angle and six flutes for smooth, consistent cutting action. The straight-cylindrical shank measures 1/4 inch in diameter, and the tool runs 2 inches in overall length. With a 3/8-inch head diameter and a bright uncoated finish, this single-end countersink is suited for right-hand cutting operations. Machinists, tool-and-die technicians, and CNC operators rely on solid carbide tooling like this for its rigidity and wear resistance in production and job-shop environments.

This countersink is built for use on a broad range of workpiece materials 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 use in drill presses, CNC machining centers, and manual mills where controlled countersinking or chamfering is required. The tool does not include a pilot and is intended as a standalone countersink, not a head-only insert.

Key Features

• 100-degree included angle for standard countersink geometry
• Six flutes deliver smooth cutting and reduced chatter
• Solid carbide construction provides rigidity and extended tool life
• Bright uncoated finish suitable for general-purpose and non-ferrous applications
• Straight-cylindrical 1/4-inch shank for broad machine compatibility
• Single-end design handles chamfering, countersinking, and deburring in one tool

Compatibility

Designed for use in standard 1/4-inch straight-cylindrical shank toolholders. Suitable for machining 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 and use should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Set spindle speed according to the workpiece material and tool diameter using standard machining feeds-and-speeds references. Secure the shank firmly in the collet or chuck to the manufacturer-specified grip length before operation.
