MITSUBISHI WCGT020104L HTI10
Super-Micro Grain Uncoated Carbide | Precision Aluminum Turning
Product Overview
The Mitsubishi WCGT020104L HTI10 is a high-precision, 80° trigonometric positive turning insert specifically engineered for non-ferrous materials. Featuring the legendary HTI10 uncoated carbide grade, this insert provides an extremely sharp cutting edge and a polished surface to prevent built-up edge (BUE). It is the industry standard for achieving mirror-like finishes on aluminum alloys, copper, brass, and plastics.

Grade: HTI10 Uncoated Carbide
HTI10 is a micro-grain uncoated carbide substrate. Unlike coated inserts, HTI10 maintains an ultra-sharp periphery, which is essential for cutting soft, gummy materials like aluminum without tearing the surface. It offers high wear resistance and excellent thermal conductivity.
Geometry: Large Rake Angle
The WCGT geometry features a large positive rake angle that reduces cutting resistance. This allows for high-speed machining with minimal vibration, ensuring that even thin-walled parts maintain their dimensional accuracy.

Frequently Asked Questions
Q: Can I use WCGT020104L on Steel?
A: We don't recommend it. HTI10 is uncoated and designed for non-ferrous metals. Steel will wear the edge very quickly.
Q: What does the 'L' stand for?
A: It stands for 'Left Hand'. Ensure your tool holder and machine rotation match this orientation.
Q: Is this insert compatible with boring bars?
A: Yes, it is commonly used in small diameter boring bars like the SWLCR series.
Pro-Tip: When to choose HTI10?
If you are experiencing material welding on your tool (where aluminum sticks to the insert), HTI10 is your solution. The lack of coating and the polished rake face allow chips to slide off instantly, preventing heat buildup and surface scratching.
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.
