Sandvik Coromant 5732810 Cutoff Insert 4mm Left Hand

Product Description

The SANDVIK COROMANT 5732810 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries the L151.2 insert style designation and belongs to the T-Max Q-Cut series, a clamp-held parting system widely used in production turning environments. The insert features a 4.00 mm cutting width, a TiAlN coating applied via PVD process, a 0-degree lead angle with left-hand orientation, a 7-degree relief angle, and a 0.30 mm corner radius. Chipbreaker geometry is 4E, suited for controlled chip formation during cutoff passes. Licensed machinists and CNC turning technicians are the typical installers of this insert type.

This insert is used in metal-cutting applications where precise parting and shallow grooving are required. The left-hand orientation and L151.2 insert style make it compatible with corresponding T-Max Q-Cut clamp-style toolholders designed for that insert seat. It is suited for both roughing and finishing cutoff passes on bar stock in medium-production and high-production turning environments. The 4E chipbreaker geometry assists with chip control across a range of workpiece materials including steel and stainless steel.

Key Features

• Solid carbide substrate, grade 1125, with PVD-applied TiAlN coating for heat and wear resistance
• 4.00 mm cutting width with 0.30 mm corner radius for consistent parting geometry
• Left-hand orientation, insert seat size 40, clamp-held mounting method
• 7-degree relief angle reduces friction and rubbing on the cut face
• 4E chipbreaker geometry supports chip control during cutoff operations
• T-Max Q-Cut series insert for use with matching clamp-style toolholders

Compatibility

Designed for use with T-Max Q-Cut series clamp-style toolholders accepting an L151.2 insert style with insert seat size 40 and left-hand orientation. Confirm toolholder insert seat designation before installation.

Installation Notes

Installation is performed by CNC machinists or turning technicians. Power down and lock out the machine before seating or removing inserts. Use the appropriate torx or hex key to torque the clamp screw per the toolholder manufacturer specifications. Inspect the insert seat for chips or debris before seating the new insert to ensure proper contact and repeatable cutting geometry.
