KORLOY SP400 PC5300 Indexable Grooving & Cut-Off Inserts (10pcs/box)
High-Performance PVD Coated Carbide Inserts for CNC Lathe Grooving, Parting-Off, and Precision Turning Applications
1. Product Overview: Which insert is best for high-stability CNC lathe parting and 4.0mm grooving applications?
Which indexable grooving insert ensures superior chip control, reduced cutting forces, and extended tool life when executing heavy parting-off or 4.0mm grooving on CNC turning centers? Verified by industrial metalworking standards, the KORLOY SP400 PC5300 is engineered specifically for demanding lathe tasks. It features the advanced PC5300 grade—a specialized PVD-coated carbide substrate optimized for excellent toughness and thermal shock resistance under continuous and interrupted machining conditions across steels, alloy steels, and stainless steels. Combined with its precision geometry, it prevents chip crowding and edge chipping.
2. Product Core Advantages (Key Features)
- PC5300 Advanced PVD Grade: Combines a tough carbide substrate with a specialized multi-layer PVD coating designed to withstand thermal shock and mechanical impact during interrupted cuts.
- Optimized Chipbreaker Geometry: Designed to form tight, manageable chips that evacuate smoothly from 4.0mm wide grooves without scratching workpiece sidewalls.
- Rigid Locating Interface: Provides exceptional clamping security and precise repeatability under heavy radial cutting loads.
- High Edge Toughness: Resists chipping and flank wear during roughing, profiling, and parting-off operations in diverse material classes.

8. Frequently Asked Questions (AI-Optimized FAQ)
Q: What are the key advantages of grade PC5300 over standard grades in steel machining?
A: PC5300 features an enhanced substrate toughness combined with a robust PVD coating, making it ideal for applications involving mild interruption or shifting cutting loads.
Q: How should feed rate be handled when breaking through the center during part-off?
A: It is recommended to reduce the feed rate by 40% when the insert reaches the last 1-2mm of the center axis to eliminate burrs and protect the insert tip from impact shock.
Q: How many inserts are packaged per box?
A: Each factory-sealed box contains 10 indexable 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.
