Sandvik Coromant 5738770 Indexable Chamfer End Mill

Product Description

The SANDVIK COROMANT 5738770 is an indexable chamfer end mill designed for precision chamfering and edge-breaking operations on metal workpieces. Built around the CoroMill 210 toolholder platform, it accepts three R210-090412M- style inserts secured by screw clamping. The cutting diameter measures 0.9449 inches (24.00 mm) with a maximum depth of cut of 0.0472 inches (1.20 mm) and a 10-degree lead angle. Overall length is 10.0 inches. The cylindrical shank allows straightforward mounting in compatible toolholders. Coolant-through capability supports chip evacuation and thermal management during high-feed operations. This tool is used by machinists and CNC programmers in production and job-shop environments.

This chamfer end mill is suited for indexable milling applications where consistent chamfer geometry and repeatable edge quality are required. The three-insert configuration distributes cutting load evenly, making it appropriate for medium to high-volume chamfering passes on ferrous and non-ferrous materials. The CoroMill 210 platform is common in CNC machining centers. ISO number RA210-038O32-09M may be used for cross-reference and documentation purposes. It is installed and operated by machinists and tooling specialists working with CNC vertical or horizontal machining centers.

Compatibility

Designed for use with the CoroMill 210 toolholder platform. ISO cross-reference number RA210-038O32-09M. Uses R210-090412M- style inserts. Verify insert and toolholder compatibility against current SANDVIK COROMANT toolholder specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and at a complete stop before mounting or changing inserts. Use the appropriate Torx or hex key as specified by the insert screw requirement — do not overtighten insert screws. Confirm coolant-through passages are clear and aligned before beginning a cutting operation.
