Sandvik Coromant 5727819 Modular Turning Head C4

Product Description

The SANDVIK COROMANT 5727819 is a modular turning profiling head designed for external turning operations in CNC machining environments. Built to the T-Max P series standard, this right-hand cutting head mounts to a C4 system interface with a C5 head connection size and projects 50 mm (1.9685 inches) from the connection face. The lever-clamping insert holding method secures CNMG 120408 indexable inserts with a center-to-cutting-edge distance of 27 mm (1.063 inches). Through-coolant capability delivers cutting fluid directly to the cutting zone, supporting higher cutting speeds and extended insert life. This head is installed by CNC machinists and toolroom technicians on modular tooling systems in production turning applications.

The 5727819 is suited for external profile turning on lathes and turning centers equipped with a compatible C4 modular quick-change tooling system. The 40 mm neck diameter provides rigidity during interrupted and continuous cuts on ferrous and non-ferrous workpieces. Applications include contour turning, facing, and shoulder work where a right-hand cutting direction is required. The CNMG 120408 insert geometry accommodates a range of materials and chip-load conditions common in job-shop and production environments.

Key Features

• T-Max P series modular head with C4 system size and C5 head connection for precise repeatability
• Right-hand cutting direction for standard external turning and profiling operations
• Through-coolant delivery channels coolant directly to the insert cutting edge
• Lever insert holding method for fast, secure CNMG 120408 indexable insert changes
• 40 mm neck diameter supports rigidity and vibration damping at the cutting zone
• Axial and radial rake angles of -6 degrees suit negative-geometry CNMG inserts

Compatibility

Designed for use with CNMG 120408 indexable inserts on C4 modular quick-change tooling systems with a C5 head connection interface. Compatible insert style is CNMG 120408 as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician with the machine spindle locked and all axes at a safe home position. Verify that the modular connection interface is clean and free of chips or coolant deposits before seating the head. Follow the tool manufacturer torque and clamping procedure for the C4 modular connection. Confirm through-coolant passages are clear and that the machine coolant system is functioning before initiating a cut.
