Sandvik Coromant 5755455 Turning Profiling Head Size 40

Product Description

The SANDVIK COROMANT 5755455 is a modular turning profiling head designed for internal profiling and turning operations on CNC lathes and machining centers. Part of the CoroTurn TR series, this left-hand cutting head features a system size 40 interface and a head length projection of 32 mm (1.26 inches). It accepts TR-VB1308 inserts secured by screw clamping, delivering rigid and repeatable cutting edge positioning. Through-coolant capability directs fluid directly to the cutting zone, extending insert life and improving chip evacuation in deep-bore or high-heat applications. This head is installed by machinists and CNC tooling specialists working in precision turning environments.

This profiling head is suited for internal turning and profiling operations where a minimum hole diameter of 50 mm (1.97 inches) is required. The left-hand cutting direction makes it appropriate for specific bore orientations and spindle configurations. The center-to-cutting-edge distance of 27 mm (1.06 inches) is a critical setup dimension when configuring tool offsets in the machine controller. It is typically used in production shops, aerospace, oil and gas, and general machining environments where modular tooling systems reduce setup time and allow quick head changes without disturbing the toolholder body.

Key Features

• System size 40 modular interface for use within compatible CoroTurn TR toolholder bodies
• Left-hand cutting direction for specific bore and spindle orientation requirements
• Head length projection of 32 mm (1.26 inches) for controlled reach into bores
• Center-to-cutting-edge distance of 27 mm (1.06 inches) for precise tool offset setup
• Through-coolant support directs coolant to the cutting edge for improved chip control and insert life
• Screw-clamp insert holding method provides rigid, repeatable insert seating

Compatibility

Compatible with TR-VB1308 inserts. Designed for use within the CoroTurn TR modular turning system at system size 40. Requires a minimum bore diameter of 50 mm (1.97 inches) for clearance.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before mounting or removing the profiling head. Verify that the mating toolholder interface is clean and free of chips or debris before assembly, as contamination at the modular joint affects runout and repeatability. Confirm tool offset values in the machine controller using the 27 mm center-to-cutting-edge dimension before initiating a cutting cycle.
