M.a. Ford 78075003 Solid Carbide Countersink 90 Deg 6 Flute

Product Description

The M.A. FORD 78075003 is a solid carbide countersink designed for chamfering, countersinking, and deburring operations across a wide range of materials. It features a 90-degree included angle and six flutes, producing clean, accurate countersunk holes in production and job-shop environments. The straight cylindrical shank measures 1/2 inch in diameter, and the tool runs 2-3/4 inches overall length. The carbide construction delivers hardness and wear resistance suited to high-cycle machining work. A tip diameter of 0.210 inches and a 45-degree centerline angle complete the geometry. Machinists, toolroom professionals, and CNC operators are the primary users.

This countersink is suited for use on CNC machining centers, drill presses, and manual mills wherever a 90-degree countersink profile is required. Its broad material compatibility makes it appropriate for production runs involving alloy steel, stainless steel, cast iron, aluminum, brass, magnesium, magnesium alloy, mild steel, high-nickel steel, high-tensile steel, Monel, and plastic. The right-hand cutting direction is standard for conventional spindle rotation. It is a single-end tool with no included pilot, so proper centering on the host hole is the operator responsibility.

Key Features

• 90-degree included angle for standard countersink and chamfer profiles
• Six flutes for smoother finish and reduced chatter compared to lower-flute-count tools
• Solid carbide body for extended tool life in abrasive and hard materials
• 1/2 inch straight cylindrical shank fits standard ER and set-screw toolholders
• Compatible with a wide range of ferrous and non-ferrous materials including stainless and high-nickel alloys
• No pilot required, offering flexibility across varying hole diameters

Compatibility

Designed as an OEM-style countersink for use in standard 1/2 inch straight-shank toolholders on CNC machining centers, drill presses, and manual milling machines requiring a 90-degree countersink profile.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the spindle is fully stopped and the machine is powered down before changing or seating the tool in the holder. Secure the straight cylindrical shank firmly in a compatible collet or set-screw holder to prevent pullout under cutting loads. Verify proper runout before beginning cuts to protect both the tool and the workpiece surface.
