Sandvik Coromant 5764381 Modular Turning Profiling Head

Product Description

The SANDVIK COROMANT 5764381 is a modular turning profiling head designed for internal turning and profiling operations on CNC lathes and turning centers. Part of the CoroTurn 107 series, this head accepts DCMT 11T308 inserts held in place by a clamp and screw method, providing secure, repeatable cutting edge positioning. It features a system size 40 with a neck diameter of 1.5748 inches (40 mm) and a head length projection of 1.2598 inches (32 mm). Through-coolant capability allows cutting fluid to be delivered directly at the cutting zone, helping manage heat and chip evacuation during deep internal passes. Installed by machinists and CNC tooling specialists, this head connects to compatible modular tooling systems via a size 20 head connection.

This profiling head is suited for internal turning operations where tight bore access and accurate profiling are required. With a minimum hole diameter of 1.9685 inches (50 mm) and a maximum hole depth of 1.2598 inches (32 mm), it is appropriate for medium-bore internal finishing and profiling in production machining environments. The right-hand cutting direction and a center-to-cutting-edge distance of 1.0630 inches (27 mm) make this head well-matched for standard right-hand internal turning setups. It is used in job shops and production facilities running medium to high volumes of turned components in steel, stainless, and similar materials where DCMT insert geometries are standard.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling specialist familiar with modular turning system assemblies. Ensure the machine spindle and turret are fully stopped and the machine is in a safe, locked-out state before mounting or removing the head. Verify head connection torque requirements against the tooling system manufacturer guidelines and confirm through-coolant passages are clear and properly aligned before operation. Do not exceed the recommended depth of cut or feed rate parameters specified for the DCMT 11T308 insert grade in use.
