Sandvik Coromant 5764258 Modular Turning Head Size 40

Product Description

The SANDVIK COROMANT 5764258 is a modular turning profiling head designed for internal turning operations on CNC lathes and turning centers. Part of the T-Max P series, this right-hand head features a size 40 system with a 32 mm head length projection and a neck diameter of 40 mm. It accepts DNMG 150608 inserts secured by a wedge clamping method, delivering repeatable edge location and rigid insert holding under heavy cutting loads. Through-coolant capability channels fluid directly to the cutting zone, extending insert life and supporting higher cutting parameters in difficult-to-reach bores.

This profiling head is suited for internal profiling and contouring in medium to large bore applications, with a minimum hole diameter of 50 mm and a maximum hole depth of 32 mm. The head connection size of 25 interfaces with compatible modular tooling bodies and adaptors in the T-Max P system. It is typically installed by machining professionals and tooling setup technicians working on production or job-shop turning equipment. The center-to-cutting-edge distance of 27 mm and the axial and radial rake geometry support controlled chip formation across a range of workpiece materials.

Key Features

• T-Max P series modular system with size 40 system interface and head connection size 25
• Accepts DNMG 150608 inserts with wedge insert holding method for rigid, repeatable clamping
• Through-coolant design directs coolant directly to the cutting edge for improved tool life
• Right-hand cutting direction with axial rake of -6 degrees and radial rake of -12 degrees
• 32 mm head length projection supports internal profiling up to 32 mm depth in bores from 50 mm minimum diameter
• Center-to-cutting-edge distance of 27 mm for predictable tool offset setup

Compatibility

Compatible with DNMG 150608 inserts. Designed for use with T-Max P series modular tooling adaptors and bodies using head connection size 25. Specific adaptor and body compatibility should be verified against the SANDVIK COROMANT T-Max P modular system documentation.

Installation Notes

Installation should be performed by a qualified machining technician with the machine spindle locked and all drives de-energized before mounting or removing the head. Ensure the head connection interface and mating adaptor are clean and free of chips or burrs before assembly to maintain concentricity and axial runout tolerances. Verify through-coolant passages are clear and that the machine coolant system pressure is within the tool system rating before operation. Follow the toolholder manufacturer torque guidelines for the clamping screw and insert wedge.
