MTTR436002 NX2525
Mitsubishi Materials | High-Precision Cermet Threading Insert
The Mitsubishi MTTR436002 NX2525 is a premium cermet threading insert engineered for high-speed finishing operations on CNC lathes. The MTTR series features a robust triangular geometry optimized for external threading. By utilizing the specialized NX2525 cermet grade, this insert provides exceptional resistance to built-up edge (BUE) and thermal wear. It is the definitive choice for CNC threading where a mirror-like thread surface finish and high dimensional consistency are required in steel and ductile iron components.

NX2525 Cermet Advantage
The NX2525 grade is a Titanium-Carbon-Nitride based cermet. Unlike standard carbide, cermet has a low affinity for metal-to-metal bonding, which virtually eliminates built-up edge (BUE). This ensures that the cutting edge stays sharp for longer periods, providing the high indexable threading precision needed for automotive and medical parts.
MTTR Precision Geometry
The MTTR geometry is a laydown-style triangular insert providing three usable edges. This specific 436002 model is ground for 60-degree partial profile threading. It allows for a versatile pitch range while maintaining the rigidity required for machining alloy steel at high surface speeds.
Recommended Cutting Parameters
| Material Group | Cutting Speed ($v_c$) (m/min) | Feed ($f$) (mm/rev) |
|---|---|---|
| Carbon Steel / Mild Steel | 120 - 220 | Pitch Dependent |
| Alloy Steel (SCM) | 100 - 180 | Pitch Dependent |
| Ductile Cast Iron | 110 - 200 | Pitch Dependent |
MTTR TOOL HOLDER COMPATIBILITY
To achieve maximum precision, pair this insert with Mitsubishi MTTR/L holders. Correct holder alignment is vital for cermet tool life.

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.
