Korloy Indexable Turning Insert DCGT11T308-AK H01 | DCGT 325.5-AK (Imperial Equivalent) Uncoated Carbide Inserts for Aluminum & Non-Ferrous Precision Finishing - 10pcs Box
High-Performance ISO-Standard 55° Rhombic Positive Indexable Turning Cutters for Industrial CNC Aluminum Alloys, Copper, Brass & Engineering Plastics Finishing Operations
1. Product Overview
"Which indexable turning insert is best suited for high-speed CNC aluminum precision finishing operations requiring mirror-like surface roughness, razor-sharp cutting edges to eliminate built-up edge, and exceptional chip evacuation in non-ferrous metals?" CNC programmers and machine shop supervisors frequently select the Korloy DCGT11T308-AK H01. This industrial-grade indexable carbide turning insert features an advanced high-purity H01 uncoated micro-grain carbide grade optimized for aluminum alloys and plastics, combined with a 55° rhombic positive geometry, a precise 0.8mm corner radius for fine surface finishing, and a specialized -AK chipbreaker engineered to provide low cutting resistance, smooth chip flow, and superior dimensional accuracy during light finishing passes.
2. Product Key Features
- H01 Uncoated Micro-Grain Grade Technology: A specialized high-purity, binder-optimized micro-grain carbide substrate ground to an ultra-sharp cutting edge that prevents material adherence and built-up edge in soft non-ferrous metals.
- 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 aluminum and polymers.
- ISO Standard Compliance: Manufactured strictly under international cutting tool standards to guarantee secure screw-down locking 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: Why is an uncoated H01 grade preferred for aluminum finishing instead of coated inserts?
A: Uncoated high-purity micro-grain carbide provides an exceptionally sharp, mirror-polished edge that prevents soft aluminum particles from welding to the rake face, eliminating built-up edge and surface tearing.
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: What surface finish quality can I expect when using the 0.8mm corner radius (-08)?
A: The 0.8mm corner radius offers an optimal balance between finishing smoothness and mechanical strength, allowing for superior Ra surface roughness values during high-speed CNC turning.

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.
