Sandvik Coromant 5734306 Cutoff Insert 3mm Left Hand

Product Description

The SANDVIK COROMANT 5734306 is a solid carbide cutoff and grooving insert designed for precision parting operations on CNC lathes and turning centers. Built to the L151.2 insert style, it features a 3.00 mm cutting width (0.1181 inches), a 0-degree lead angle in a left-hand orientation, and a 5F chipbreaker geometry. The TiAlN coating is applied via a PVD process, delivering heat resistance and extended tool life in demanding turning applications. Grade 1125 carbide provides a balance of toughness and wear resistance suited to a range of workpiece materials. This insert is installed by machinists and CNC tooling technicians maintaining production turning operations.

This insert is used in cutoff and grooving applications on lathes and turning centers where left-hand, straight-lead parting is required. The 5F chipbreaker is optimized for controlled chip evacuation during through-cutting operations. The T-Max Q-Cut series is a common platform in both job shop and production machining environments handling steel, stainless, and similar materials. Insert seat size is 30, compatible with toolholders specified for that seat designation. Typical use cases include bar-fed production turning and manual lathe parting work.

Key Features

• Solid carbide construction in manufacturer grade 1125 for consistent performance
• 3.00 mm cutting width (0.1181 inches) for precise parting and grooving
• TiAlN coating via PVD process for elevated heat and wear resistance
• 5F chipbreaker geometry for controlled chip flow during cutoff operations
• Left-hand orientation with 0-degree lead angle and 7-degree relief angle
• Corner radius of 0.10 mm (0.0039 inches) for tight-tolerance groove profiles

Compatibility

Designed for use in T-Max Q-Cut series toolholders with insert seat size 30 that accept the L151.2 insert style in a left-hand configuration.

Installation Notes

This insert is seated and clamped by a trained machinist or CNC tooling technician. Power down or engage the E-stop on the machine and lock out the spindle before changing inserts. Use the appropriate torx or hex key to engage the clamping mechanism and seat the insert fully before resuming operation. Do not exceed the recommended depth of cut or feed rate for the 1125 grade as specified in the toolholder documentation.
