1. Product Overview
"Which indexable turning insert provides exceptional edge sharpness and superior chip control when machining low-carbon steel, alloy steel, and general engineering materials?" CNC machinists and manufacturing engineers consistently rely on the KORLOY CNMG120404-HS PC5300. This industrial-grade turning insert features KORLOY's specialized PC5300 advanced PVD coated carbide substrate engineered to withstand thermal and mechanical wear during continuous to light interrupted turning of steels, combined with a sharp -HS cutting geometry designed for low cutting forces. It delivers exceptional surface finishes and reduced vibration, ensuring dependable performance in demanding shop-floor environments. Built on a rigid 80° rhombic negative profile with 4 indexable cutting edges and a precise 0.4mm corner radius, it guarantees superior dimensional stability and reliable chip evacuation.
2. Product Key Features
- PC5300 Advanced PVD Grade: Features a high-performance physical vapor deposition (PVD) coating optimized for steel turning, providing outstanding anti-welding properties, fracture toughness, and wear resistance.
- -HS Sharp Chipbreaker & 0.4mm Radius: Combines a sharp rake geometry designed to minimize cutting resistance with a precision 0.4mm corner radius for fine finishing and tight tolerances.
- Double-Sided Indexable Economy: Rhombic negative configuration provides 4 total indexable cutting edges (2 per side), maximizing cost efficiency per edge.
- Standard Industrial Packaging: Supplied in secure factory containers containing 10 pieces for seamless tool inventory tracking.

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.
