Sandvik Coromant 5740221 Ball Nose End Mill 1 in

Product Description

The SANDVIK COROMANT 5740221 is a 1-inch diameter indexable ball nose end mill from the CoroMill 216 series, designed for high-performance profiling and contouring in steel and similar materials. The body is steel construction with a Weldon flat shank and integrated through-coolant capability to support chip evacuation and thermal management during cutting. Two ball nose inserts of style RA216-2504 are secured via screw clamping. With an overall length of 4.5311 inches and a maximum depth of cut of 0.8930 inches, this tool suits deep-reach finishing and semi-finishing passes on CNC machining centers.

This end mill is intended for use on CNC vertical and horizontal machining centers running demanding profiling operations on steel workpieces. The Weldon flat shank provides positive drive and resistance to pullout under aggressive feed rates. Through-coolant delivery supports extended insert life and consistent surface finish. The 2-flute, 2-insert design is well-suited to die and mold work, contoured part finishing, and general semi-finish milling in production and job-shop environments. Installation and setup are performed by skilled machinists and CNC setup technicians.
