MTTR436001 UTI20T
Mitsubishi Materials | Precision Threading & Grooving Insert
The Mitsubishi MTTR436001 UTI20T is a specialized threading insert designed for high-stability performance on CNC lathes. The MTTR geometry is a triangle-based precision profile, often utilized for external threading where edge strength is paramount. Unlike coated inserts, the UTI20T uncoated carbide grade provides an incredibly sharp cutting edge, making it the professional choice for threading non-ferrous metals, cast iron, and general steel applications where coating delamination is a concern.
Technical Specifications
| ISO Designation | MTTR436001 |

| ANSI Designation | MTTR 43 60 01 |
| Carbide Grade | UTI20T (Uncoated Carbide) |
| Hand of Tool | Right Hand (R) |
| Primary Application | Steel, Stainless Steel, Cast Iron |
UTI20T Material Composition
The UTI20T grade is a versatile P20-P30 / K20 grade uncoated carbide. It is engineered for general-purpose machining across a wide range of materials. Because it lacks a thick PVD/CVD layer, the cutting edge remains extremely sharp, reducing cutting resistance and preventing work hardening in sensitive materials like austenitic stainless steel.
MTTR Geometry Features
The 43-size threading insert offers a robust substrate that absorbs vibrations during heavy-duty threading. Its precision-ground profile ensures high thread surface finish quality and dimensional accuracy, making it ideal for indexable threading where tight tolerances are required.

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.
