Sandvik Coromant 5722978 Turning Insert Ccgt Tialn Coroturn 107

Product Description

The SANDVIK COROMANT 5722978 is a solid carbide turning insert designed for precision external turning operations on steel and stainless steel workpieces. It carries the ISO designation CCGT 09 T3 04-UM 1105 and belongs to the CoroTurn 107 series. The insert features an 80-degree diamond shape (C insert shape code), a TiAlN coating applied via PVD process, and a UM chip breaker geometry. With a 3/8 inch inscribed circle, a 0.365 inch insert length, and a 1/64 inch corner radius, it delivers consistent chip control in light to medium turning passes. This insert is installed by CNC machinists and tool-crib technicians on positive-rake turning tool holders.

The 5722978 is suited for turning operations on steel (ISO material code P) as the primary workpiece material, with stainless steel (ISO material code M) as the secondary material. The UM chip breaker geometry targets finishing and semi-finishing cuts where tight chip control and surface finish consistency are critical. It is commonly mounted in CoroTurn 107 tool holders that accept CCGT-style inserts with screw-type clamping. Applications include shaft turning, facing, and profiling on CNC lathes in production and job-shop environments.

Key Features

• 80-degree diamond insert shape provides a strong cutting edge with good approach-angle flexibility
• TiAlN coating via PVD process enhances wear resistance and thermal stability during steel cutting
• UM chip breaker geometry optimized for light to medium finishing passes
• 1/64 inch corner radius for improved surface finish on precision turning applications
• Neutral hand orientation compatible with standard CCGT tool holder setups
• Screw-type insert holding for secure clamping and repeatable edge indexing

Compatibility

Designed for use in CoroTurn 107 series tool holders that accept CCGT-style screw-clamped turning inserts. Compatible workpiece materials include steel (ISO P) and stainless steel (ISO M).

Installation Notes

Turning inserts must be installed by qualified machinists or tooling technicians following the tool holder manufacturer's clamping torque and seating procedures. Always index or replace the insert with the machine fully powered down and the spindle locked. Use appropriate insert extraction tools to avoid contact with sharp cutting edges. Verify seating and clamping security before resuming cutting operations.
