M.a. Ford. 27743712B Corner Radius End Mill Head 4 Flute

Product Description

The M.A. FORD. 27743712B is a solid carbide corner radius end mill head engineered for precision milling operations in metalworking and machining applications. This 4-flute head features a right-hand cutting and right-hand flute direction with a variable helix angle ranging from 38 to 41 degrees and a variable index design. The variable helix and index geometry reduces harmonic vibration during cutting passes, allowing for improved surface finish and more consistent chip evacuation. At 2.75 inches in length with a 0.5 inch cutting width and 0.5 inch height, this head is sized for tight-tolerance work. It is installed by machinists and CNC operators working with modular end mill systems.

This corner radius end mill head suits precision milling operations in ferrous and non-ferrous materials where a radiused corner profile is required to reduce stress concentrations or meet part geometry specifications. The helical flute design with variable helix and variable index is particularly suited to high-speed finishing and semi-finishing passes on CNC machining centers. The solid carbide construction supports use in rigid, high-RPM setups where tool deflection must be minimized. Typical installation environments include job shops, aerospace component machining, die and mold work, and general precision part manufacturing.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cutting operations
• 4-flute helical design supports efficient chip evacuation and improved surface finish
• Variable helix angle (38 to 41 degrees) reduces harmonic vibration during cutting
• Variable index geometry further dampens chatter for consistent tool performance
• Corner radius end type reduces stress concentration at part corners versus a square end
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed as a modular replacement-style corner radius end mill head for use with compatible modular end mill systems accepting this head form factor and shank interface.

Installation Notes

Installation of end mill heads should be performed by a qualified machinist or CNC operator following the tool manufacturer torque and interface specifications for the modular system in use. Ensure the machine spindle is fully stopped and the CNC program is in a safe-hold state before changing any cutting tool head. Inspect the mating shank interface for damage, chips, or contamination before seating the head. Follow all applicable shop safety procedures and machine guarding requirements during tool changes.
