Sandvik Coromant 5737072 Cutoff Insert Carbide 3mm

Product Description

The SANDVIK COROMANT 5737072 is a solid carbide cutoff insert in the T-Max Q-Cut series, designed for parting and grooving operations on CNC lathes and turning centers. It carries the N151.2-300-4E 1125 designation, indicating insert style N151.2, a 3.00 mm cutting width, a 4E chipbreaker geometry, and manufacturer grade 1125. The grade uses a PVD-applied TiAlN coating, which supports wear resistance at elevated cutting temperatures. A neutral lead angle and a 7-degree relief angle make this insert suitable for straight-in parting cuts on a range of workpiece materials. The corner radius measures 0.30 mm. Overall length is 5.46 mm. The insert is held by a clamp-style toolholder compatible with the T-Max Q-Cut system.

This insert is intended for production turning environments where consistent parting and grooving performance is required. It is sized for insert seat size 30 toolholders within the T-Max Q-Cut platform. Typical applications include cutoff operations on bar stock and workpieces in ferrous and non-ferrous materials where the 4E chipbreaker geometry helps control chip formation and evacuation. Machinists and CNC operators in job shops, production facilities, and maintenance machining environments install this insert as a direct replacement in compatible T-Max Q-Cut clamp-style toolholders. This product is sold individually and carries a minimum order quantity of 10 units.

• 7-degree relief angle reduces rubbing and supports clean part separation
• 0.30 mm corner radius for precise groove-bottom profile
• Clamp-style insert holding for secure seating in T-Max Q-Cut toolholders

Compatibility

Designed for use with T-Max Q-Cut series clamp-style toolholders accepting insert seat size 30 and insert style N151.2. Refer to toolholder documentation to confirm correct insert seat and clamping compatibility before installation.

Installation Notes

This insert is installed and replaced by machinists and CNC lathe operators. Power down and lock out the machine spindle before changing inserts. Use the correct T-Max Q-Cut clamping key to seat and secure the insert without overtightening the clamp screw. Inspect the toolholder pocket and clamp for wear or damage each time the insert is replaced to maintain accurate positioning and safe cutting conditions.
