Sandvik Coromant 5765143 Modular Grooving Head System Size 40

Product Description

The SANDVIK COROMANT 5765143 is a left-hand modular grooving head designed for use in the CoroCut 1-2 modular tooling system. It functions as a cutting head that mounts to a compatible modular shank and performs external grooving and parting operations on CNC lathes and turning centers. The head accepts N123 size G inserts and supports through-coolant delivery for improved chip evacuation and tool life. Key working dimensions include a maximum depth of cut of 4.00 mm (0.157 inches), a minimum groove width of 3.00 mm (0.118 inches), and a center-to-cutting-edge distance of 45.10 mm (1.7756 inches). This component is installed by machinists and CNC turning specialists in production and job-shop environments.

This grooving head is suited for System Size 40 CoroCut 1-2 modular assemblies used in precision turning applications. It is appropriate for both production machining and toolroom use where repeatable grooving geometry and quick insert changeability are required. The left-hand cutting direction makes it applicable to specific workpiece orientations and spindle configurations where right-hand tooling is not suitable. Compatible inserts are identified by the full insert designation N123G2-0300-GM. The head length projection is 14.00 mm (0.5512 inches), and the maximum groove width capacity is 18.00 mm (0.7087 inches).

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. The machine spindle must be fully stopped and the turret or tool post must be in a safe, locked position before mounting or removing the modular head. Use the appropriate torque wrench and interface tooling specified by the modular system manufacturer when securing the head to the shank body. Verify insert seating and clamping before resuming cutting operations.
