Sandvik Coromant 5764371 Modular Turning Head Size 25

Product Description

The SANDVIK COROMANT 5764371 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 right-hand head features a Size 25 system with a 20 mm (0.7874 inches) head length projection and a neck diameter of 25 mm (0.9843 inches). It accepts DCMT 11T308 inserts secured by a clamp and screw holding method, and includes through-coolant capability for improved chip evacuation and tool life in deep internal bore work. Licensed machinists and CNC operators install this head as part of a modular tooling assembly.

This profiling head is suited for internal turning applications where modular flexibility is required. The head connection size is 32, making it compatible with corresponding CoroTurn 107 modular shanks and adapters. It is used in production environments where bore profiling, facing, and contour turning inside diameters are required. The minimum hole diameter this head can operate in is 32 mm (1.2598 inches), with a maximum hole depth of 20 mm (0.7874 inches). The center to cutting edge distance is 17 mm (0.6693 inches), which is a critical reference value when setting tool offsets in the machine controller.

Compatibility

Designed for use with the SANDVIK COROMANT CoroTurn 107 modular tooling system at head connection size 32. Compatible insert style is DCMT 11T308. Refer to the CoroTurn 107 system documentation to confirm compatible shank and adapter combinations for your specific machine setup.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom personnel familiar with modular turning systems. Power down and lock out the machine spindle before mounting or removing the head. Confirm the head connection interface is clean and free of chips or debris before assembly to ensure proper seating and runout. Follow the tool manufacturer torque guidelines for the clamping screw and verify tool offset values, particularly the center to cutting edge dimension, in the machine controller before commencing cuts.
