Sandvik Coromant 5734309 Cutoff Insert 3mm T-max Q-cut

Product Description

The SANDVIK COROMANT 5734309 is a solid carbide cutoff and grooving insert engineered for the T-Max Q-Cut system. It carries the manufacturer catalog designation L151.2-30005-4E 2135 and is designed to part off and groove ferrous and non-ferrous workpieces on CNC and manual lathes. The insert features a 3.00 mm cutting width, a 0-degree lead angle with left-hand orientation, and a 4E chipbreaker geometry. An MTCVD-applied TiCN/Al2O3/TiN coating provides wear resistance and thermal stability during high-speed parting operations. Grade 2135 delivers a balance of toughness and hardness suited for continuous and mildly interrupted cuts in steel.

This insert is used in production turning environments where consistent parting depth and chip control are critical. Typical applications include bar-fed CNC turning centers and turret lathes performing repetitive cutoff operations on steel, alloy steel, and similar materials. The left-hand insert hand and 0-degree lead angle make it appropriate for standard right-to-left parting setups. The 4E chipbreaker geometry assists with chip evacuation in medium to finish-depth grooving passes. It is installed by machinists and CNC setup technicians in shop environments requiring tight dimensional control on parted components.

• 4E chipbreaker geometry promotes controlled chip formation and evacuation
• 0-degree lead angle, left-hand orientation for standard parting setups
• Clamp-style insert holding method for secure, repeatable seating in compatible toolholders
• Grade 2135 carbide suited for medium to finish cutting conditions in steel

Compatibility

Designed for use in SANDVIK COROMANT T-Max Q-Cut toolholders accepting insert style L151.2 with insert seat size 30. Verify toolholder designation before installation.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or replacing the insert. Use the designated clamping screw and appropriate torque driver per toolholder manufacturer guidelines — do not overtighten by estimate. Inspect the insert seat and clamp for chips or debris before installation to ensure proper seating and repeatable tool height.
