Korloy Indexable Turning Insert DCGT070202-AK H01 | DCGT 21.505-AK (Imperial Equivalent) Uncoated Carbide Inserts for Micro-Machining Aluminum & Non-Ferrous Finishing - 10pcs Box
High-Performance ISO-Standard 55° Rhombic Positive Micro Indexable Turning Cutters for Industrial Swiss Lathes, CNC Aluminum Alloys, Copper & Precision Medical Components
1. Product Overview
"Which micro indexable turning insert is best suited for Swiss-type CNC lathe operations requiring tight tolerance precision finishing on small aluminum and non-ferrous components without burrs or built-up edge?" CNC programmers and precision machine shop supervisors frequently select the Korloy DCGT070202-AK H01. This industrial-grade miniature indexable carbide turning insert features an advanced high-purity H01 uncoated micro-grain carbide grade optimized for non-ferrous metals and plastics, combined with a 55° rhombic positive geometry, an ultra-precise 0.2mm corner radius for tight corner profiling and fine finishing, and a specialized -AK chipbreaker engineered to provide low cutting resistance, smooth chip control, and mirror-like surface integrity during delicate micro-machining passes.
2. Product Key Features
- H01 Uncoated Micro-Grain Grade Technology: A specialized high-purity binderless micro-grain carbide substrate ground to an extreme edge sharpness that eliminates built-up edge when machining soft aluminum and copper.
- Optimized -AK Chipbreaker Geometry: Sharp positive rake angle design with a polished top rake face engineered to lower cutting forces and deliver flawless surface finishes on miniature parts.
- ISO Standard Compliance: Manufactured strictly under international cutting tool standards to guarantee secure screw-down locking and exact interchangeability across standard positive miniature 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: Why is the 0.2mm small corner radius (-02) chosen for Swiss lathe precision finishing?
A: The 0.2mm corner radius provides a tighter profiling capability for sharp internal corners, fine shoulders, and micro-diameters where larger radii would cause undercutting.
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: Is coolant required when running the H01 grade on aluminum micro-components?
A: Yes, applying high-pressure water-miscible coolant is strongly recommended to evacuate micro-chips cleanly and maintain stable low temperatures during high-speed Swiss machining.

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.
