The Original Korloy TPGH090202L-CRT PC5300 (ANSI: TPGH 21.50.5L-CRT) is an elite PVD Coated Turning Insert specifically optimized for Precision Finishing in gummy and difficult-to-machine materials. Featuring the renowned PC5300 Universal Grade, this insert excels in Stainless Steel (M), Heat Resistant Alloys (S), and Alloy Steel (P). The sharp 0.2mm (0.008") radius combined with the CRT micro-geometry ensures clean cuts and superior dimensional stability for Swiss-type CNC lathes.
High Performance PVD Technology: PC5300 is engineered with a ultra-fine substrate and high-aluminum content PVD coating. This provides the perfect balance of edge sharpness and mechanical toughness, preventing the premature edge peeling often seen when machining 300-series stainless steel.
Technical Specifications (Metric & Imperial):
| ISO Designation | TPGH 090202L-CRT |
| ANSI Designation | TPGH 21.50.5L-CRT |
| Inscribed Circle (IC) | 5.56 mm / (7/32") |
| Thickness (S) | 2.38 mm / (3/32") |
| Corner Radius (r) | 0.2 mm / (0.008") |
| Grade | PC5300 (High-Toughness PVD) |
Core Performance Benefits:
- Anti-Welding Properties: Specialized coating reduces friction to stop Built-Up Edge (BUE) in stainless and aluminum.
- Precision Detail Work: The 0.2mm radius allows for extremely sharp internal corners and fine contouring.
- Reliability in Interrupted Cuts: Unlike cermet, the PC5300 substrate can absorb mechanical shocks from cross-holes or slots.
- Universal Grade: One solution for diverse materials including Stainless 304/316, Titanium, and 4140 Steel.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 80-160 m/min | 0.03-0.08 mm/rev | 0.05-0.4 mm |
| Heat Resistant Alloys | 30-70 m/min | 0.02-0.07 mm/rev | 0.05-0.3 mm |
Compatible Tool Holders:
Fits all standard 09-size triangular tool holders:
- Swiss-Type Gang Tooling: STGCR 1212H09 / STGCR 1616H09

Machinist Tip: PC5300 vs. PC9030
Selecting the right PVD grade for Stainless:
The Universal Precision Choice. Best for fine finishing where edge sharpness is critical. It offers higher wear resistance on a wider variety of materials including carbon steels.
The Stainless Specialist. Best for medium cutting and heavy interrupted cuts specifically in Stainless Steel. It is slightly tougher but less wear-resistant in alloy steels compared to PC5300.
Pro Advice: If you are experiencing "built-up edge" (material sticking to the tip), increase your cutting speed (Vc) and ensure high-pressure coolant is directed exactly at the tool tip.
Packaging: 10 pieces per box.
