Mitsubishi 10520857 Corner Radius End Mill Head 10mm

Product Description

The MITSUBISHI 10520857 is a solid carbide corner radius end mill head designed for high-performance milling operations. With a 10mm (0.3937 inch) mill diameter and 1mm (0.0394 inch) corner radius, this eight-flute head delivers precise edge geometry and reduced corner chipping in demanding cutting applications. The AlCrN coating provides excellent heat and wear resistance, extending tool life in ferrous and hardened materials. It mounts via an iMX12 connection type and features through-coolant capability to manage heat and chip evacuation during deep or high-speed passes. Licensed machinists and CNC tool setters are the primary installers.

This end mill head is suited for finish and semi-finish milling in both ferrous and non-ferrous materials where corner integrity and surface finish are critical. The 35-degree helical flute angle and right-hand cutting direction make it a standard choice for conventional CNC machining centers. The non-centercutting design means it is used in side milling, profiling, and contouring operations rather than plunge cutting. Its compact overall length of 33.7mm (1.3268 inches) supports rigid setups in tight workpiece environments.

Key Features

• AlCrN coating for superior heat resistance and extended tool life in hard materials
• Eight helical flutes with 35-degree helix angle for efficient chip evacuation
• 1mm corner radius reduces stress concentration and protects part edges
• Through-coolant capable for temperature control in high-speed milling
• iMX12 modular connection for quick, repeatable head changes without full tool replacement
• Solid carbide construction provides rigidity and dimensional stability under cutting loads

Compatibility

Designed for use with iMX12-compatible modular end mill arbors and toolholding systems. Verify arbor connection size and pull-out specifications before installation.

Installation Notes

Installation requires a compatible iMX12 modular toolholder and appropriate torque wrench as specified by the toolholder manufacturer. Ensure the spindle and toolholder are clean and free of chips or debris before seating the head. Follow machine tool builder guidelines for runout inspection after mounting. Non-centercutting geometry means plunge entry must not be performed with this head.
