Sandvik Coromant 7419254 Corner Radius End Mill 10mm 5 Flute

Product Description

The SANDVIK COROMANT 7419254 is a solid carbide corner radius end mill engineered for high-performance material removal in superalloys and titanium. Part of the CoroMill Plura Series 2F341, it features a 10 mm cutting diameter, a 0.5 mm corner radius, and five helical flutes ground to a close pitch for aggressive roughing operations. The tool carries a multilayer PVD TiAlSiN coating, which provides thermal resistance and edge hardness under the elevated cutting temperatures common when machining difficult materials. A 10 mm straight-cylindrical shank with h6 tolerance ensures consistent clamping in standard toolholders. Overall length is 72 mm, with a 22 mm length of cut and an extended reach of 30 mm supported by a 9.5 mm neck diameter. CNC machinists and tool-and-die professionals will find this cutter suited to finishing and semi-finishing passes where edge integrity is critical.

This end mill is intended for use in CNC machining centers handling superalloys and titanium workpieces, including aerospace components, medical implants, and high-temperature turbine parts. Its extended-reach geometry makes it practical for deep-pocket and shoulder milling where a standard-length tool cannot reach the floor. The right-hand flute direction and right-hand cutting rotation are compatible with conventional vertical and horizontal machining center spindles. Single-end configuration means the tool is replaced rather than reversed when worn.

Key Features

• 10 mm cutting diameter with h10 tolerance for consistent fitment
• 0.5 mm corner radius reduces stress concentrations and extends tool life on hard materials
• Multilayer PVD TiAlSiN coating for thermal and wear resistance in superalloy and titanium applications
• Five helical flutes at close pitch optimized for roughing material removal rates
• Extended-reach design with 30 mm reach length and 9.5 mm neck diameter for deep-pocket access
• Straight-cylindrical shank with h6 tolerance for secure clamping in standard toolholders

Compatibility

Designed for use with standard toolholders accepting a 10 mm straight-cylindrical shank. Optimized for machining superalloys and titanium workpieces; primary material application code S per Sandvik Coromant classification.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Ensure the machine spindle is fully stopped and the controller is in a safe state before changing tooling. Seat the shank fully in the toolholder and torque the clamping mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing cuts, as excess runout accelerates edge wear on carbide tooling used in superalloys and titanium.
