Sandvik Coromant 5746686 Modular Turning Profiling Head

Product Description

The SANDVIK COROMANT 5746686 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 cutting head accepts CNMG 120408 inserts retained by a lever-style clamping mechanism. It features a neck diameter of 1.26 inches (32 mm) and a head length projection of 1.26 inches (32 mm), with a center-to-cutting-edge distance of 0.87 inches (22 mm). Through-coolant capability delivers cutting fluid directly to the cutting zone, extending insert life and improving chip evacuation in deep bore applications. Licensed machinists and CNC turning specialists install this head as part of a modular tooling system.

This profiling head is suited for internal turning, boring, and profiling in precision machining environments, including aerospace, automotive, and general engineering applications. It is compatible with modular head connection size 40 systems. The minimum hole diameter it can enter is 1.57 inches (40 mm), and the maximum hole depth capacity is 1.26 inches (32 mm). Applications include finishing and semi-finishing of internal profiles where consistent insert indexing and coolant management are critical to achieving tight tolerances.

Key Features

• T-Max P series modular design allows quick head changes without removing the entire tool assembly
• Through-coolant support for improved chip control and extended insert life in internal operations
• Lever-style insert clamping provides secure, repeatable CNMG 120408 insert seating
• Right-hand cutting direction with axial rake of -6 degrees and radial rake of -11 degrees for controlled cutting geometry
• Head connection size 40 for compatibility with corresponding modular shank bodies
• Minimum hole diameter of 1.57 inches (40 mm) suits a broad range of bore sizes

Compatibility

Designed for use with modular turning systems accepting a head connection size 40. Compatible insert style is CNMG 120408. Intended for internal, right-hand turning operations within the T-Max P modular tooling platform.

Installation Notes

This head is installed by qualified CNC machinists or tooling specialists familiar with modular turning system assembly. Ensure the machine spindle and coolant supply are fully shut down before mounting or removing the profiling head. Follow the tooling manufacturer torque and seating procedures for the head connection interface to ensure proper alignment and rigidity. Confirm insert grade and geometry selection is appropriate for the workpiece material before operation.
