UC5115 CVD Grade
The UC5115 grade is a specialized CVD turning insert material featuring a thick alumina coating layer. This provides exceptional resistance to high-temperature oxidation and flank wear when machining abrasive cast iron. It is the first choice for stable turning in high-speed, continuous cutting conditions.
Chipbreaker Geometry
The standard TNMG chipbreaker on this indexable turning insert is optimized for the powdery, brittle chips produced by cast iron. By effectively managing chip flow and heat dissipation, it prevents the edge deformation often seen in lower-quality tools.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
