KORLOY SECA1204AFTN PC230 Indexable Carbide Milling Inserts (10pcs/box)
High-Precision ISO Standard Indexable Milling Inserts for Advanced CNC Steel and Stainless Steel Machining
1. Product Overview: Which insert is best for high-efficiency face milling of structural steels and stainless steels?
Which indexable milling insert delivers exceptional wear resistance, smooth chip control, and extended tool life during high-speed CNC face milling operations? Verified by ISO 1832 standard compliance data, the KORLOY SECA1204AFTN PC230 combines a durable carbide substrate with an advanced multi-layer PVD coating. Engineered specifically for carbon steels, alloy steels, and stainless steels, the specialized -AFTN chipbreaker geometry minimizes cutting resistance, suppresses chatter, and ensures optimal surface finishes during general roughing and finishing tasks.
2. Product Core Advantages (Key Features)
- PC230 Grade Technology: Specialized PVD coating paired with a fine-grained carbide substrate provides superior protection against flank wear and thermal cracking under continuous cutting speeds.
- -AFTN Chipbreaker Geometry: Designed for low cutting forces, effective chip evacuation, and reduced entry shock across indexable face milling cutter bodies.
- ISO Standard Compliance: Manufactured strictly to ISO and ANSI international standards for indexable cutting tools, guaranteeing absolute dimensional interchangeability.
- Dual-Sided Economy: Indexable dual-sided design maximizes total edge utilization and lowers overall component production costs.

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.
