VP10RT Miracle Grade
The VP10RT grade is a high-hardness Miracle PVD coated carbide. Compared to VP20RT, it offers significantly higher wear resistance and edge stability, making it ideal for stable, continuous cutting at higher speeds in steel and alloy steels.
GM Chipbreaker Geometry
The GM (General Machining) chipbreaker is designed for balanced performance. It excels in diverse grooving depths, ensuring stable chip breaking into manageable "6" or "C" shapes, which is critical for preventing long chip entanglements in CNC lathe processes.

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.
