Mitsubishi 682734 Corner Chamfer End Mill 3/4 in 4 Flute

Product Description

The MITSUBISHI 682734 is a solid carbide corner radius corner chamfer end mill head designed for high-performance milling operations in metalworking and machining applications. With a 3/4 inch (19.05 mm) mill diameter, a 4-flute helical configuration, and a variable helix angle ranging from 42 to 45 degrees, this head delivers stable cutting and reduced chatter in demanding materials. The AlCrN coating provides thermal resistance and extended tool life in dry or semi-dry cutting environments. It connects via the iMX20 interface, making it a modular insert-style head for compatible tooling systems. Installation and removal are handled by qualified machinists or toolroom personnel.

This end mill head is suited for finish milling, chamfering, and corner radius profiling on ferrous and non-ferrous metals in both production and job-shop environments. The variable helix and variable index geometry help suppress harmonic vibration during aggressive cuts. With a 3/4 inch length of cut and a corner radius of 0.060 inch (1.52 mm), it is well matched to contouring and edge-blending operations on mold, die, and precision machined components. It is not center-cutting and should not be used for direct plunge operations.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlCrN coating for high thermal stability and extended tool life
• Variable helix (42 to 45 degrees) and variable index geometry reduce vibration and chatter
• iMX20 modular connection for secure, repeatable head changes
• 4-flute right-hand helical flute design for efficient chip evacuation
• Corner radius of 0.060 inch (1.52 mm) protects edge integrity and improves surface finish

Compatibility

Designed for use with iMX20 modular end mill systems. Consult the toolholder manufacturer specifications to confirm shank and interface compatibility before installation.

Installation Notes

This end mill head is installed by a machinist or toolroom technician using the appropriate iMX20 torque wrench and toolholder per the system manufacturer guidelines. Ensure the machine spindle is fully stopped and the toolholder is secured in a stable fixture before seating or removing the head. Do not use this head for plunge cutting, as it is not center-cutting. Verify runout with a dial indicator after assembly to confirm proper seating.
