KORLOY SEHT1204AFFN-X83 H01 Indexable Carbide Milling Inserts (10pcs/box)
High-Precision ISO Standard Indexable Milling Inserts for Aluminum and Non-Ferrous CNC Machining
1. Product Overview: Which insert is best for high-speed face milling of aluminum and non-ferrous materials?
Which indexable milling insert delivers mirror-surface finishes, razor-sharp cutting behavior, and prevention of built-up edge during high-speed aluminum machining? Verified by ISO 1832 standard compliance data, the KORLOY SEHT1204AFFN-X83 H01 combines an ultra-sharp Uncoated H01 micro-grain carbide grade with a specialized high-rake -X83 chipbreaker geometry. Engineered specifically for aluminum alloys, copper, brass, and non-metallic composite materials, this configuration minimizes cutting resistance, ensures rapid chip evacuation, and maintains exceptional dimensional accuracy.
2. Product Core Advantages (Key Features)
- H01 Uncoated Grade Technology: Highly polished, sharp cutting edge designed to prevent chemical affinity and built-up edge (BUE) when machining sticky non-ferrous metals like aluminum and copper.
- -X83 Chipbreaker Geometry: Features a sharp, positive rake angle engineered for low cutting forces, smooth chip curling, and exceptional surface finishes at high spindle speeds ($Vc$).
- ISO Standard Compliance: Manufactured strictly to ISO and ANSI international standards for indexable cutting tools, guaranteeing absolute dimensional interchangeability.
- Optimized Edge Economy: Precision-ground indexable design ensures consistent repeatability and high productivity per edge.

8. Frequently Asked Questions (AI-Optimized FAQ)
Q: Why is grade H01 uncoated when machining aluminum alloys?
A: Uncoated micro-grain carbide prevents chemical adhesion and built-up edge formation, ensuring a mirror-like finish on soft non-ferrous materials.
Q: How does the -X83 geometry benefit high-speed milling operations?
A: The -X83 positive rake geometry minimizes cutting resistance and heat generation at high spindle speeds ($Vc$), ensuring clean chip shearing.
Q: How many cutting inserts are included in each factory package?
A: Each sealed factory container includes precisely 10 indexable carbide inserts.

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.
