Sandvik Coromant 5751831 Turning Insert Coroturn 107

Product Description

The SANDVIK COROMANT 5751831 is a solid carbide turning insert designed for external turning operations on CNC lathes and turning centers. Configured in the TCGX style with a 60-degree triangular shape, this insert delivers three usable cutting edges per insert. It carries a multi-layer MTCVD coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous and interrupted cuts. Part of the CoroTurn 107 series, it is engineered for screw-clamped toolholders and is suited for finish to medium turning passes on steel and stainless steel workpieces. The inscribed circle measures 5/32 inches (6.35 mm) and the corner radius is 1/64 inches (0.40 mm).

This insert is intended for use in the CoroTurn 107 series toolholding system and targets primary machining of steel (ISO P) and secondary machining of stainless steel (ISO M). Typical applications include finish turning of shafts, flanges, and bores in production environments where consistent surface finish and close tolerances are required. The WK chipbreaker geometry is optimized for light to medium depths of cut, with a maximum depth of cut of 0.2449 inches (6.22 mm). Right-hand cutting orientation suits standard spindle-forward setups. This insert is sold individually; minimum order quantity is 10 units.

Key Features

• MTCVD multi-layer coating: TiCN, Al2O3, and TiN for wear resistance and heat control
• WK chipbreaker geometry suited for finish to medium turning on steel and stainless steel
• Three cutting edges per insert for extended tool life per unit
• Screw-clamped insert holding method for secure, repeatable seating in CoroTurn 107 holders
• Maximum depth of cut of 6.22 mm (0.2449 inches) for medium-duty passes
• ISO code TCGX06T104RWK1515 for cross-reference with standard tooling catalogs

Compatibility

Designed for use with SANDVIK COROMANT CoroTurn 107 series screw-clamped toolholders. ISO insert code TCGX06T104RWK1515 may be used to identify compatible holders from other manufacturers that accept TCGX-style inserts with the same seat dimensions.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or insert-clamping screw driver specified for the CoroTurn 107 holder to avoid overtightening or stripping the clamping screw. Inspect the insert pocket seat for chips or debris before seating the new insert, as contamination in the pocket can affect insert stability and surface finish.
