Sandvik Coromant 5727885 Modular Turning Profiling Head C4

Product Description

The SANDVIK COROMANT 5727885 is a modular turning profiling head designed for internal boring and profiling operations on CNC lathes and turning centers. Part of the CoroTurn 107 series, this right-hand head features a Size C4 system with a C5 head connection, a head length projection of 2.7559 inches (70 mm), and a center-to-cutting-edge distance of 0.4331 inches (11 mm). It accepts CCMT 09T308 inserts held by a clamp and screw method, and includes through-coolant capability to extend tool life and improve chip evacuation in deep-bore applications. Installed by machinists and CNC toolroom technicians.

This profiling head is suited for internal turning and profiling in bore diameters starting at a minimum of 0.7874 inches (20 mm) with a maximum hole depth of 2.7559 inches (70 mm). It is used in precision turning applications in metalworking environments including aerospace, automotive, and general machining where consistent bore geometry and surface finish are required. The modular CoroTurn 107 interface allows the head to be exchanged on compatible shanks without disturbing setup, reducing changeover time on multi-part runs.

Key Features

• CoroTurn 107 modular system with C4 size and C5 head connection for repeatable positioning
• Through-coolant design supports extended tool life and chip control in deep internal features
• Accepts CCMT 09T308 inserts via clamp and screw holding for rigid, predictable cutting
• Minimum bore diameter of 0.7874 inches (20 mm) suits a wide range of internal profiling applications
• Right-hand cutting direction; radial rake angle of -8.3967 degrees optimized for CCMT insert geometry
• Head length projection of 2.7559 inches (70 mm) enables reach into deeper bore features

Compatibility

Compatible with CCMT 09T308 inserts. Designed for use with CoroTurn 107 series modular boring and turning systems using a C5 head connection interface.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician following the machine tool and tooling system manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or exchanging modular heads. Torque the head connection to the tooling system specification using calibrated tooling wrenches. Verify through-coolant passages are clear and coolant supply is correctly pressurized before initiating a cut.
