M.a. Ford. 277XX750B Square End Mill 3/4 in 4 Flute Carbide

Product Description

The M.A. FORD. 277XX750B is a solid carbide square end mill engineered for demanding material removal applications. It features a 3/4-inch cutting diameter with a 4-1/8-inch length of cut, making it suitable for deep-pocket and slotting operations where extended reach is required. The four-flute configuration uses a variable helix angle of 38/41 degrees to break up harmonic chatter and improve surface finish at higher feed rates. An AlCrN coating provides elevated heat resistance and oxidation protection, extending tool life in ferrous and hard alloy workpieces. This tool is installed and operated by machinists and CNC tooling professionals in job shop and production environments.

This end mill is used in vertical and horizontal CNC machining centers as well as manual knee mills capable of handling 3/4-inch tooling. Its extra-long length of cut makes it well suited for deep-pocket milling, side milling, and profiling operations where standard-length tools cannot reach. The right-hand cutting and right-hand flute direction are compatible with conventional spindle setups. The micrograin carbide substrate supports use in hardened steels, stainless alloys, cast iron, and similar materials where tool rigidity and edge retention are critical.

Key Features

• 3/4-inch cutting diameter with 4-1/8-inch length of cut for extended deep-pocket reach
• Variable helix design at 38/41 degrees reduces chatter and improves cut stability
• AlCrN coating delivers high oxidation resistance and extended tool life in ferrous materials
• Micrograin solid carbide substrate provides superior rigidity and edge retention
• Center-cutting geometry allows plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand flute direction for standard CNC and manual mill setups

Compatibility

Designed for use in CNC machining centers and manual mills with standard 3/4-inch collet chucks, end mill holders, or shrink-fit toolholders. Suitable for deep-pocket and profile milling in ferrous metals, hardened steels, stainless alloys, and cast iron.

Installation Notes

This tool should be installed by a qualified machinist using a properly sized and clean 3/4-inch toolholder to ensure runout is within acceptable limits. Always confirm spindle speed and feed rate parameters are appropriate for the workpiece material before engaging the cut. Inspect the tool shank and holder bore for chips or contamination before seating. Do not exceed the rated length of cut when programming depths of engagement, as overextension can cause deflection or tool breakage.
