Walter-prototyp 7745628 Corner Radius End Mill Head

Product Description

The WALTER-PROTOTYP 7745628 is a solid carbide corner radius end mill head designed for precision milling operations in metalworking and machining applications. Built with 4 flutes and a spiral flute design, this replaceable head delivers clean corner radius profiles with consistent edge geometry. The right-hand cutting direction and right-hand flute direction suit standard milling setups. Material grade WJ30TF indicates a carbide substrate formulated for demanding cutting conditions. At a length of cut of 0.15 inches, this head is suited for finish and semi-finish passes where accurate corner blending is required. It weighs 0.06 pounds, making it a lightweight component in modular tooling systems.

This end mill head is intended for use in modular or interchangeable head milling systems common in CNC machining centers and manual knee mills. It is typically installed by machinists and tooling technicians working in job shops, aerospace, automotive, and general metalworking environments. The corner radius end type reduces stress concentration at the cutting edge and extends tool life compared to sharp-corner end mills, making it a practical choice for profiling, contouring, and finishing passes on ferrous and non-ferrous materials.

Key Features

• Solid carbide construction using material grade WJ30TF for wear resistance in demanding cuts
• 4-flute spiral configuration for efficient chip evacuation and surface finish
• Corner radius end type reduces edge chipping and extends tool life on profile passes
• Right-hand cutting and flute direction compatible with standard CNC spindle rotation
• Length of cut: 0.15 inches, optimized for finish and semi-finish milling operations
• Replaceable head design reduces tooling cost compared to solid shank end mills

Compatibility

Designed as a replacement-style corner radius end mill head for modular milling tooling systems that accept interchangeable carbide heads matching this head geometry and thread interface. Verify head interface compatibility with your specific toolholder before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or removing the end mill head. Use the manufacturer-recommended torque tool or key for the modular head interface - do not overtighten by hand. Inspect the mating threads and seating surface on the toolholder for damage or contamination before assembly.
