Sandvik Coromant 5755421 Turning Insert 13mm Diamond Carbide

Product Description

The SANDVIK COROMANT 5755421 is a solid carbide turning insert designed for precision metal-cutting operations on CNC lathes and turning centers. Part of the CoroTurn TR series, it features a diamond (T) insert shape with a 60-degree included angle and carries a dual-layer PVD coating of TiAlN and AlCr2O3 for elevated heat resistance and edge durability at the cutting zone. The insert measures 13 mm in length with a 13 mm inscribed circle diameter and a 0.40 mm (1/64 inch) corner radius. It is a neutral-hand insert, making it suitable for both right- and left-hand tool holders equipped with screw clamping. Licensed machinists and CNC turning specialists install this insert in production and job-shop environments.

This insert is engineered primarily for turning stainless steel (ISO material code M) and is rated for secondary use on superalloys and titanium (ISO code S). The F chip breaker geometry promotes controlled chip formation at moderate feed rates and depths of cut up to 12.60 mm. It fits CoroTurn TR toolholders that accept the TRVB 1304 seat size and is identified by ISO code TRVB1304F1115. The 1115 grade designation indicates a PVD-coated carbide substrate optimized for the toughness demands of stainless and high-temperature alloy work.

Key Features

• PVD-applied TiAlN and AlCr2O3 dual-layer coating for thermal and wear resistance in stainless and superalloy cutting
• Diamond insert shape (60-degree T code) with 2 cutting edges for extended tool life per insert
• F chip breaker geometry supports controlled chip evacuation at moderate feeds
• Screw-clamp holding method compatible with CoroTurn TR seat configuration
• 0.40 mm (1/64 inch) corner radius balances surface finish and edge strength
• Maximum depth of cut rated to 12.60 mm (0.4961 inch)

Compatibility

Designed for CoroTurn TR toolholders accepting TRVB 1304 insert seat size. ISO code TRVB1304F1115 identifies the toolholder and insert interface. Primary material compatibility is stainless steel (ISO M); secondary compatibility covers superalloys and titanium (ISO S).

Installation Notes

Installation is performed by a qualified CNC machinist or tool-crib technician. Ensure the machine spindle is fully stopped and the turret is indexed away from the work zone before replacing inserts. Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer specification — do not overtighten. Inspect the insert pocket and seating surface for chips or debris before indexing or replacing the insert to maintain accurate tool geometry.
