Sandvik Coromant 5740211 Indexable Chamfer End Mill

Product Description

The SANDVIK COROMANT 5740211 is an indexable chamfer end mill designed for precision chamfering and beveling operations on metalworking equipment. Part of the U-Max series, it accepts one SPMT 12 04 08 insert secured by a screw-type holding method. The cutter operates across a cutting diameter range of 0.472 inches to 0.903 inches, with a maximum depth of cut of 0.379 inches. The 19.05mm Weldon Flat shank provides secure tool holding in compatible spindles. Overall length is 4.528 inches. This tool is typically installed by machinists and CNC tooling technicians working in production and job-shop environments.

This chamfer end mill suits applications requiring consistent chamfer angles on ferrous and non-ferrous workpieces. The 60-degree lead angle produces a 30-degree included angle chamfer, making it appropriate for deburring, edge preparation, and countersink-style chamfering on milling centers and machining centers. The single-insert design simplifies insert indexing during production runs. The Weldon Flat shank is compatible with standard side-lock tool holders commonly found in vertical and horizontal milling setups.

Key Features

• 60-degree lead angle producing a 30-degree included chamfer on the workpiece edge
• Cutting diameter range of 0.472 inches to 0.903 inches for variable chamfer width
• Single SPMT 12 04 08 insert, screw-clamped for repeatable positioning and fast indexing
• Maximum spindle speed of 25,200 RPM suitable for high-speed milling applications
• Weldon Flat shank at 19.05mm diameter for secure side-lock tool holder engagement
• Steel body construction with 115mm overall length for reach into standard milling setups

Compatibility

The 5740211 uses the RA215.64..Mxx toolholder style and accepts SPMT 12 04 08 inserts. It is designed for use in compatible Weldon Flat side-lock tool holders with a 19.05mm bore. No additional compatible model numbers were specified in the product data.

Installation Notes

This tool should be installed by a qualified machinist or CNC tooling technician following the machine manufacturer's tooling guidelines. Power down and lock out the spindle before inserting or removing the tool or indexing the insert. Secure the Weldon Flat shank with the appropriate side-lock set screw torqued per the tool holder manufacturer's specification. Verify runout with a dial indicator before initiating a cut, and confirm spindle speed does not exceed the 25,200 RPM maximum rating.
