Shop SCLC Boring BarsPro Tip: NX2525 vs VP15TF
NX2525 (Cermet): Your first choice for Precision Finishing. Cermet has a much lower affinity for steel than carbide, which prevents "built-up edge" (BUE) and results in a mirror finish. Best for continuous cuts.
VP15TF (PVD Carbide): Switch to VP15TF for interrupted cuts or medium roughing. Cermets are harder but more brittle; carbide provides the toughness needed for heavy shocks.

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.
