Sandvik Coromant 5749961 Turning Profiling Head Size 40

Product Description

The SANDVIK COROMANT 5749961 is a modular turning profiling head engineered 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 secured by a lever clamping method, delivering reliable insert retention under interrupted and continuous cut conditions. The head features a 40 mm neck diameter and a 35 mm head length projection, with a center-to-cutting-edge distance of 27 mm (1.063 inches). Through-coolant capability is built in, directing fluid directly to the cutting zone to manage heat and extend insert life in deep-bore profiling applications.

This profiling head is suited for internal bore profiling on medium-to-large diameter workpieces in production turning environments. The minimum hole diameter supported is 50 mm (1.969 inches), with a maximum hole depth matching the 35 mm head projection. The modular system connection size is 40, allowing integration with compatible T-Max P modular tool assemblies. Typical applications include profiling bores, contouring, and finishing in ferrous and non-ferrous materials where consistent insert indexing and coolant delivery are required. Installation and tool assembly are performed by qualified CNC machinists or tooling technicians.

Key Features

• T-Max P series modular system with size 40 head connection for repeatable tool assembly
• Lever insert clamping secures CNMG 120408 inserts for stable cutting under load
• Through-coolant delivery directs fluid to the cutting edge for thermal control and chip evacuation
• Right-hand cutting direction with axial rake of -6 degrees and radial rake of -10 degrees for controlled chip formation
• 40 mm neck diameter supports rigidity in internal bore applications with 50 mm minimum hole diameter
• 35 mm head length projection defines maximum bore depth reach for this configuration

Compatibility

Designed for use with CNMG 120408 inserts in T-Max P series modular turning assemblies with a size 40 head connection. Compatible insert style is CNMG 120408 as specified by the manufacturer.

Installation Notes

This head is installed by a qualified CNC machinist or tooling technician as part of a modular turning assembly. The machine spindle must be brought to a full stop and all energy sources locked out before assembling or changing modular heads. Torque the modular connection per the tool assembly instructions provided by the manufacturer for the specific coupling interface. Verify through-coolant passages are clear and unobstructed before initiating a cut.
