M.a. Ford. 27743700B Square End Mill 7/16 in 4 Flute Carbide

Product Description

The M.A. FORD. 27743700B is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin carbide, it delivers a 7/16 inch (0.4375 inch) cutting diameter and a 1/2 inch length of cut. The variable helix design at 38 and 41 degrees reduces chatter and improves chip evacuation during aggressive cuts. An AlCrN coating provides heat and wear resistance, extending tool life in ferrous and hardened materials. This is a right-hand cut, right-hand flute, single-end configuration — the standard setup for CNC machining centers and manual mills alike.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous metals, stainless steels, and hardened materials where heat resistance and edge stability are critical. The standard length profile and 7/16 inch shank diameter make it compatible with common collet systems found in vertical and horizontal machining centers. It is centercutting, allowing plunge entry. Machinists and CNC operators working in production or job-shop environments will find this tool appropriate for tight-tolerance finish passes as well as aggressive roughing strategies depending on depth-of-cut parameters.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• Variable helix at 38 and 41 degrees reduces harmonic vibration and chatter
• AlCrN coating provides high-temperature and oxidation resistance
• Centercutting design allows direct plunge entry
• Right-hand cut and right-hand flute configuration for standard spindle operation
• 4-flute helical design supports both roughing and finishing passes

Compatibility

Designed as an OEM-style replacement end mill compatible with standard 7/16 inch collet or end mill holder systems on CNC machining centers and manual vertical mills.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated per shop safety procedures. Ensure the collet or tool holder is clean and free of debris before seating the shank. Torque the collet nut to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
