Sandvik Coromant 5752112 Turning Insert Tcgt Triangle

Product Description

The SANDVIK COROMANT 5752112 is a solid carbide turning insert in the TCGT style, designed for external turning operations on CNC lathes and turning centers. It carries a TiAlN and AlCr2O3 dual-layer PVD coating over the carbide substrate, which supports elevated cutting speeds and edge wear resistance. The insert is grade 1125 and features a 60-degree triangular geometry with a K-style chip breaker, making it well suited for finishing and light roughing passes. With three usable cutting edges per insert, it delivers consistent performance across its service life. A licensed machinist or CNC operator performs the indexing and installation.

This insert is part of the SANDVIK COROMANT CoroTurn 107 series, engineered for positive-rake turning applications. It is primarily applied to steel workpieces and is also rated for stainless steel, non-ferrous metals, superalloys, and titanium, covering ISO material groups P, M, N, and S. The right-hand cutting orientation and screw-holding method make it compatible with standard CoroTurn 107 toolholders. Typical applications include finishing passes on turned components in general machining, aerospace, and energy industry work.

Key Features

• TiAlN and AlCr2O3 PVD coating for heat resistance and edge durability at high cutting speeds
• Grade 1125 carbide substrate optimized for steel and multi-material turning
• 60-degree triangular insert shape provides three indexable cutting edges per insert
• K-style chip breaker designed for controlled chip formation on finishing and light roughing operations
• Right-hand cutting orientation with screw-mount holding method for positive insert location
• 7-degree relief angle (clearance code C) reduces flank contact and improves surface finish

Compatibility

Designed for use in SANDVIK COROMANT CoroTurn 107 series toolholders that accept TCGT-style inserts with screw clamping. ISO designation for this insert is TCGT 09 02 04R-K 1125.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. Before indexing or replacing the insert, confirm that the machine spindle is stopped and all axis motion is locked out per shop safety procedures. Seat the insert flat against the toolholder pocket and tighten the clamping screw to the toolholder manufacturer specification. Inspect the cutting edge and chip breaker geometry before resuming cuts to confirm correct seating.
