Sandvik Coromant 5736994 Grooving Insert Solid Carbide Tialn

Product Description

The SANDVIK COROMANT 5736994 is a solid carbide grooving insert designed for the T-Max Q-Cut series of parting and grooving toolholders. It carries a TiAlN coating applied via PVD process, delivering heat resistance and edge durability during interrupted and continuous grooving operations. The insert is neutral-hand, making it compatible with both left- and right-hand setups. Key cutting geometry specs include a 0.189-inch (4.80 mm) cutting width, a 0.3191-inch cutting height, and a 0.0224-inch corner radius. Manufacturer grade is 1125, a PVD-coated carbide grade suited for steel and stainless steel grooving at moderate to high cutting speeds. Installation is performed by machining professionals and CNC operators working with grooving and parting applications.

This insert is used in external grooving, parting-off, and face grooving operations on CNC lathes and turning centers. The 4G chip breaker geometry controls chip formation and evacuation during grooving passes, which reduces the risk of chip packing in the groove. The neutral rake angle of 7 degrees supports stable cutting action across a range of work materials. The ISO code for this insert is N151.2-A189-40-4G 1125, and it belongs to insert seat size 40 within the T-Max Q-Cut system. It is a multi-use tool appropriate for production and maintenance turning environments.

Key Features

• Solid carbide substrate with PVD-applied TiAlN coating for heat and wear resistance
• 0.189-inch cutting width with 0.0224-inch corner radius for precise groove geometry
• 4G chip breaker promotes controlled chip evacuation during deep grooving and parting operations
• Neutral-hand orientation allows use in both left- and right-hand toolholder setups
• Insert seat size 40 matches T-Max Q-Cut toolholder bodies within the N151.2 series
• Multi-use designation supports grooving, parting, and face grooving on a single insert style

Compatibility

Designed for use with SANDVIK COROMANT T-Max Q-Cut toolholders accepting N151.2 series inserts at insert seat size 40. ISO code N151.2-A189-40-4G 1125 identifies the exact toolholder seat and insert geometry pairing required for proper seating and clamping.

Installation Notes

Insert replacement should be performed by a qualified CNC operator or machinist with the machine in a full stop, spindle locked, and all energy isolated per lockout/tagout procedures. Use the appropriate SANDVIK COROMANT torx or hex key specified for the T-Max Q-Cut clamping screw — do not overtighten or substitute non-OEM fasteners. Inspect the insert pocket and clamping screw for wear or contamination before seating the new insert. Verify the insert is fully seated and clamped before resuming cutting operations.
