Sandvik Coromant 5764394 Modular Turning Head Size 25

Product Description

The SANDVIK COROMANT 5764394 is a modular turning profiling head designed for internal left-hand turning operations. Part of the CoroTurn 107 series, this head mounts to compatible modular boring and turning systems at a size 25 head connection. It accepts DCMT 11T308 inserts held by a clamp and screw method, delivering consistent insert positioning for profiling and finishing work in bores. Through-coolant capability directs fluid directly to the cutting zone, extending insert life and improving chip evacuation during deep or interrupted cuts. The head projects 20 mm (0.787 inches) and requires a minimum hole diameter of 32 mm (1.260 inches), making it suited to mid-range bore diameters on CNC lathes and turning centers.

This profiling head is intended for internal turning applications in metalworking environments, typically on CNC turning centers and lathes running ferrous and non-ferrous materials. The left-hand cutting direction suits specific approach angles and spindle configurations where a standard right-hand head cannot be used. The center-to-cutting-edge distance of 17 mm (0.669 inches) and the -6-degree radial rake angle are optimized for controlled chip formation during contour and profile passes inside bores. Machinists and CNC setup technicians working in precision machining shops are the primary users of this tool.

Key Features

• CoroTurn 107 series modular system, size 25 head connection for repeatable, tool-change-ready setup
• Compatible with DCMT 11T308 inserts using clamp and screw holding for secure, rigid insert seating
• Through-coolant design channels fluid to the cutting edge for improved tool life and chip control
• Left-hand internal cutting direction for bore profiling where right-hand approach is not possible
• 17 mm (0.669 inches) center-to-cutting-edge distance with -6-degree radial rake for controlled chip formation
• 20 mm head length projection; minimum hole diameter 32 mm (1.260 inches)

Compatibility

Designed for use with SANDVIK COROMANT CoroTurn 107 modular turning systems at size 25 head connection. Uses DCMT 11T308 inserts. Verify system compatibility with the matching modular shank or adaptor at size 25 before ordering.

Installation Notes

Installation is performed by CNC machinists or toolroom technicians on CNC lathes or turning centers. De-energize and lock out the machine before mounting or removing modular heads. Torque the head connection and insert clamp screw according to the SANDVIK COROMANT CoroTurn 107 assembly documentation supplied with the tooling system. Confirm through-coolant passages are clear and the machine coolant circuit is compatible before initiating cuts.
