Sandvik Coromant 5731436 Turning Toolholder DTFNR164D

Product Description

The SANDVIK COROMANT 5731436 is a right-hand indexable turning toolholder in the DTFNR164D style, part of the T-Max P series. It uses a wedge clamping method to secure TNMG 22 04 08 inserts with a negative rake geometry at a rake angle of -6 degrees. The shank measures 1 inch wide by 1 inch tall, with an overall length of 6 inches. Constructed from steel, this toolholder is designed for negative-rake external turning operations on CNC lathes and manual turning centers. It is installed and maintained by machinists and toolroom technicians.

This toolholder fits standard OD turning applications on production lathes where a right-hand cutting direction is required. The DTFNR164D style positions the insert for side-facing and profiling cuts on workpiece materials compatible with TNMG 22 04 08 insert geometry. The T-Max P series is engineered for steel-shank rigidity in demanding turning environments, making it suitable for both roughing and finishing passes when paired with the appropriate insert grade. It is commonly used in job shops, aerospace, and general machining environments.
