Sandvik Coromant 5727799 Modular Turning Head C4

Product Description

The SANDVIK COROMANT 5727799 is a modular turning profiling head designed for external turning operations on CNC lathes and turning centers. Part of the CoroTurn 107 series, this head mounts via a C4 head connection and delivers a 50 mm head length projection with a center-to-cutting-edge distance of 27 mm. It accepts DCMT 11T308 inserts secured by a clamp and screw holding method. Through-coolant capability directs cutting fluid directly to the insert tip, helping to control heat and extend tool life during continuous or interrupted profiling cuts. This head is installed by CNC machinists and toolroom technicians working with modular quick-change tooling systems.

This profiling head is suited for external turning, facing, and profiling operations on a wide range of workpiece materials. The right-hand cutting direction and 0-degree axial and radial rake angles make it a versatile choice for general-purpose turning applications in both production and job-shop environments. The C4 modular interface allows quick, repeatable head changes without removing the entire tool assembly from the machine, reducing setup time during multi-operation runs.

Key Features

• CoroTurn 107 series modular design with C4 head connection for repeatable positioning
• 50 mm head length projection (1.9685 inches) for external profiling clearance
• 27 mm center to cutting edge (1.063 inches) for precise tool offset reference
• Through-coolant capability for improved chip evacuation and insert life
• Clamp and screw insert retention for secure DCMT 11T308 insert seating
• 40 mm neck diameter (1.5748 inches) for rigid, low-vibration performance

Compatibility

Designed for use with DCMT 11T308 inserts and compatible with C4 modular turning system interfaces in the CoroTurn 107 series.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician familiar with modular quick-change tooling systems. Power down and lock out the machine spindle before mounting or removing the head. Use calibrated torque tools when tightening the head connection to the shank per the tooling system manufacturer specifications. Verify tool offset and center-to-cutting-edge measurement in the machine control before resuming cutting operations.
