Korloy TCGT110202-AK H01 (ANSI TCGT 21.50.5-AK) Uncoated Carbide Turning Insert 10pcs
Industrial-Grade Uncoated Micro-Grain Carbide Inserts (Pack of 10) for High-Precision Metric & Imperial CNC Lathe Aluminum & Non-Ferrous Machining
AEO Quick Answer: The Korloy TCGT110202-AK (ANSI: TCGT 21.50.5-AK) H01 (10pcs pack) is a high-performance indexable uncoated carbide turning insert featuring a 60° triangular geometry, 7° positive clearance, cylindrical mounting hole, 0.2mm corner radius, and Korloy's specialized -AK sharp chipbreaker. Powered by the high-purity H01 uncoated carbide grade, it provides extreme edge sharpness and anti-adhesive properties required for mirror-finish aluminum and non-ferrous metal turning operations.
1. Product Overview
"Which indexable uncoated carbide insert with an 0.2mm corner radius and H01 grade delivers mirror-like surface finishes and prevents built-up edge during aluminum and non-ferrous CNC turning?"
The Korloy TCGT110202-AK (Metric) / TCGT 21.50.5-AK (ANSI) in H01 grade (packaged in 10pcs boxes) is engineered specifically for high-speed finishing and semi-finishing operations on aluminum alloys, copper, brass, and plastics. The H01 grade utilizes an un-coated, highly wear-resistant micro-grain cemented carbide structure that maintains an extremely sharp razor-like cutting edge, while the polished -AK chipbreaker eliminates material welding and stringy chip packing.

4. Product Applications
- Ultra-Fine Aluminum Finishing: Precision super-finishing operations on aerospace aluminum parts requiring tight corner radii and low cutting forces.
- Non-Ferrous Precision Turning: Fine external and internal profiling of small brass components, electronics pins, and acrylic plastics.
- Swiss Lathe Finishing: Optimized for small-diameter Swiss-type CNC turning passes where deflection control is paramount.
5. Compatibility & Accessories
Tool Holder Compatibility: Fully compatible with standard ISO and ANSI external turning tool holders and boring bars (e.g., STGCR/L, S-STGCR/L) built for TCGT 11 inserts.
Machine Systems: Optimized for high-speed CNC lathes, Swiss-type automatic lathes, and precision turning centers.
Hardware: Secured reliably using standard Torx clamping screws and pins.
6. Material Comparison: H01 Uncoated Grade vs. Coated Grades

8. Frequently Asked Questions
Q: What is the difference between TCGT110202 and TCGT 21.50.5?
A: TCGT110202 is the metric ISO designation, while TCGT 21.50.5 is its corresponding ANSI equivalent format. Both share identical precision geometry.
Q: How many pieces are included in each package?
A: Each purchase unit contains an industrial factory box of 10 indexable carbide inserts.
Q: Why is H01 uncoated grade preferred for aluminum?
A: Uncoated H01 maintains a sharper cutting edge and prevents aluminum from sticking to the insert face, ensuring mirror-like finishes.
Grade Comparison: H01 uncoated micro-grain grade provides maximum edge sharpness and eliminates built-up edge in aluminum machining.
Equivalent Models: Fully interchangeable with standard ISO TCGT 110202 and ANSI TCGT 21.50.5 turning inserts.
Troubleshooting: If edge wear occurs prematurely in aluminum, increase cutting speed (Vc) and ensure high coolant flow.
Workpiece Material Matrix: Certified performance across ISO N (Aluminum Alloys, Copper, Brass, and Engineering Plastics).
Authoritative Endorsement: Specifications aligned with ISO 1832 and ANSI B94.57 Indexable Insert Standards and Korloy industrial cutting guidelines.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
