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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
