The Original Korloy TPGH110302L-CRT PC5300 (ANSI: TPGH 32.50.5L-CRT) is a heavy-duty PVD Coated Turning Insert designed for Ultra-Precision Finishing in demanding materials. Powered by the versatile PC5300 Grade, this insert excels where others fail—providing extreme edge toughness for Stainless Steel (M), Heat Resistant Alloys (S), and High-Strength Steels (P). Its 11-size footprint offers maximum stability, while the 0.2mm (0.008") radius enables intricate detail work on large-scale precision components.
Engineered for Toughness: The PC5300 grade combines a sub-micron substrate with an advanced AlTiN PVD coating. This specific combination is designed to resist thermal shock and mechanical chipping, making it the ideal choice for finishing parts with interrupted cuts or gummy surface characteristics like 316L stainless.
Technical Specifications (Metric & Imperial):
| ISO Designation | TPGH 110302L-CRT |
| ANSI Designation | TPGH 32.50.5L-CRT |
| Inscribed Circle (IC) | 6.35 mm / (1/4") |
| Thickness (S) | 3.18 mm / (1/8") |
| Corner Radius (r) | 0.2 mm / (0.008") |
| Grade | PC5300 (Tough PVD Specialist) |
Core Performance Benefits:
- Enhanced Rigidity: The 11-size (1/4" IC) triangular body offers the best vibration dampening in the TPGH family.
- Excellent Chip Control: The CRT chipbreaker is specifically tuned for light depths of cut, ensuring "bird-nesting" is eliminated on gummy materials.
- Oxidation Resistance: The PVD coating maintains hardness at high temperatures, allowing for consistent finishing passes.
- 0.2mm Precision: Perfect for sharp internal corners and micro-contouring in aerospace and medical device manufacturing.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 80-170 m/min | 0.03-0.10 mm/rev | 0.05-0.45 mm |
| Alloy Steel / 4140 | 120-210 m/min | 0.03-0.12 mm/rev | 0.05-0.5 mm |
| Titanium Alloys | 40-75 m/min | 0.02-0.08 mm/rev | 0.05-0.35 mm |
Compatible Tool Holders:
Optimized for use with 11-size triangular tool systems:
- Large Internal Boring Bars: S12M-STUPR11 / S16Q-STUPR11 / S20R-STUPR11
Machinist Tip: PC5300 vs. CN2000 (Cermet)
Making the right choice for your final pass:
The Tough Fighter. Choose this for stainless steel, titanium, or any setup where vibrations or interrupted cuts are present. It prevents the catastrophic chipping that ruins expensive parts.
The Mirror Maker. Only use Cermet on clean, continuous cuts in carbon or alloy steel when you need a "mirror finish" and Ra surface values below 0.4μm.
Pro Advice: For internal boring in stainless steel, always use the 11-size TPGH if space allows. The extra insert thickness provides the rigidity needed to maintain a consistent 0.2mm corner radius under cutting pressure.
Packaging: 10 pieces per box.

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.
