M.a. Ford. 278 0400N3-0.25 Corner Radius End Mill Head

Product Description

The M.A. FORD. 278 0400N3-0.25 is a solid carbide corner radius end mill head designed for precision milling operations in metalworking and machining applications. Built with 5 helical flutes in a right-hand cutting and right-hand flute direction, this head delivers smooth chip evacuation and consistent finish quality. The 4.00 mm mill diameter and 11 mm length of cut make it well suited for detail work and profiling passes where accurate corner geometry is required. Variable index spacing reduces chatter and improves surface finish in demanding cuts. The overall length is 57 mm. Licensed machinists and CNC operators are the primary installers and users of this tooling component.

This end mill head is intended for use in compatible modular tooling systems that accept interchangeable end mill heads of this diameter and shank standard. It is applicable in job shop, tool room, and production CNC milling environments handling ferrous and non-ferrous materials. The corner radius end type protects the cutting edge and reduces stress concentration at the corner, making it appropriate for finishing and semi-finishing passes on contoured or flat workpiece surfaces. Package quantity is 1 unit per order.

Key Features

• Solid carbide construction for hardness and wear resistance in demanding milling applications
• 5 helical flutes with right-hand cutting direction for efficient chip removal
• Variable index flute spacing reduces harmonic chatter and improves surface finish
• Corner radius end type extends tool life by reducing edge chipping at the cutting corner
• 4.00 mm mill diameter and 11 mm length of cut for detail and profiling work
• 57 mm overall length suits standard modular end mill head systems

Compatibility

Designed as a replacement-style modular end mill head for compatible tooling systems accepting a 4.00 mm solid carbide corner radius head with right-hand helical geometry. Consult the tooling system manufacturer specifications to confirm shank and interface compatibility before installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle must be fully powered down and the tool changer disabled before handling or installing end mill heads. Use the appropriate torque wrench and interface tool specified by the modular tooling system manufacturer when seating the head. Inspect the mating interface surfaces for chips, debris, or wear before assembly to ensure proper seating and runout performance.
