Korloy Indexable Turning Insert DCGT11T302-AK H01 | DCGT 32.505-AK (Imperial Equivalent) Uncoated Carbide Inserts for High-Precision Aluminum & Non-Ferrous Ultra-Finishing - 10pcs Box
High-Performance ISO-Standard 55° Rhombic Positive Indexable Turning Cutters for Industrial CNC Aluminum, Brass, Copper & Non-Ferrous Ultra-Precision Mirror Finishing Operations
1. Product Overview
"Which indexable turning insert is best suited for ultra-precision CNC aluminum and non-ferrous metal finishing operations requiring mirror-like surface finishes, razor-sharp cutting edges for tight corner radii, and complete elimination of built-up edge?" CNC programmers and machine shop supervisors frequently select the Korloy DCGT11T302-AK H01. This industrial-grade indexable carbide turning insert features an advanced high-performance H01 uncoated sub-micron carbide grade optimized for non-ferrous alloys, combined with a 55° rhombic positive geometry, a fine 0.2mm corner radius for sharp shoulder profiling and low depth-of-cut finishing, and a specialized -AK chipbreaker engineered to provide effortless chip flow, exceptionally low cutting forces, and superior workpiece integrity during high-speed precision passes.
2. Product Key Features
- H01 Uncoated Sub-Micron Grade Technology: A highly polished, razor-sharp uncoated carbide substrate engineered specifically to prevent material adhesion, built-up edge (BUE), and chemical reaction when machining aluminum and copper alloys.
- Optimized -AK Chipbreaker Geometry: Sharp positive rake angle design with a wide polished breaker groove engineered to minimize cutting resistance and ensure clean chip evacuation at high rotational speeds.
- ISO Standard Compliance: Manufactured strictly under international cutting tool standards to guarantee secure screw clamping and exact interchangeability across standard positive external turning tool holders and boring bars.
- Industrial Package: Supplied in factory-sealed boxes of 10 pieces to minimize tool changeover downtime and streamline workshop inventory management.

8. Frequently Asked Questions (FAQ)
Q: What is the main operational advantage of choosing the 0.2mm corner radius (-02) over a 0.4mm radius?
A: The 0.2mm corner radius allows for machining sharper internal profile corners and shoulder radii with minimal undercutting, while keeping radial cutting forces extremely low for delicate micro-components.
Q: How many inserts are included in each factory package?
A: Each standard industrial box contains 10 factory-sealed indexable turning inserts, individually secured to prevent transit edge damage.
Q: Why is an uncoated H01 grade essential for aluminum mirror finishing?
A: Uncoated sub-micron carbide produces a sharper micro-edge than coated grades, cleanly shearing aluminum crystals and preventing the chemical adhesion that causes built-up edge (BUE).

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.
