Sandvik Coromant 5723906 Turning Insert CCMT21.50-WF

Product Description

The SANDVIK COROMANT 5723906 is a CCMT-style diamond-shaped turning insert designed for precision external and internal turning operations on CNC lathes and turning centers. Manufactured from solid carbide and coated with a TiAlN and AlCr2O3 multilayer finish applied via PVD process, it delivers strong wear resistance and thermal stability at the cutting edge. The insert features a 0.25-inch inscribed circle, a 0.2 mm corner radius, and a neutral hand orientation. The WF chip breaker geometry controls chip flow during finishing and light roughing passes. This insert is intended for machinists and CNC programmers working in production or job-shop turning environments.

The 5723906 is engineered primarily for steel (ISO material code P) with a secondary rating for stainless steel (ISO material code M). It fits into the CoroTurn 107 series tooling system and is suited for both positive-rake boring bar and external turning holder setups. The WF chip breaker geometry is optimized for finishing and semi-finishing operations where tight chip control and consistent surface finish are required. Its ISO designation is CCMT 06 02 02-WF 1125, which aligns it with standard CCMT insert pockets in compatible toolholders across the CoroTurn 107 platform.

Key Features

• TiAlN and AlCr2O3 multilayer PVD coating for wear resistance and thermal protection
• WF chip breaker geometry optimized for finishing and semi-finishing on steel and stainless steel
• 0.2 mm corner radius for tight tolerance profiling and light finishing passes
• 80-degree diamond insert shape (code C) with 7-degree relief angle for positive cutting action
• Neutral hand orientation for use in both right-hand and left-hand holder configurations
• Screw-clamped insert holding method for secure, repeatable seating in the pocket
• 2 cutting edges per insert for extended service before disposal

Compatibility

Designed for use in SANDVIK COROMANT CoroTurn 107 series toolholders and boring bars with CCMT 06 02 02 insert pockets. ISO designation CCMT 06 02 02-WF 1125 can also be used to cross-reference compatible third-party toolholders accepting standard CCMT pockets with screw clamping.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or toolroom technician with the machine in a full stop and lockout-tagout procedures applied. Seat the insert fully into the pocket before tightening the clamping screw to avoid seating errors or edge chipping. Inspect the insert pocket and seating surface for debris or wear before each index. Handle carbide inserts with care to avoid chipping the cutting edges during storage or installation.
