WNMG 080412 T9205 — ISO turning insert for turning by Tungaloy

WNMG080412-NM T9205 is a CVD-coated carbide insert engineered for productive external and internal turning of steel in stable setups

• CVD-coated cemented carbide T9205
• Designed for productive steel turning
• ISO WNMG 080412 NM geometry
• 80° trigon shape with cylindrical hole

High-performance grade for productive steel turning

The CVD-coated T9205 grade combines wear resistance and thermal stability to extend tool life under elevated cutting speeds. As a cemented carbide solution, it resists flank wear and maintains edge stability, which reduces unplanned tool changes and supports continuous production. The result is a measurable improvement in process reliability and a better cost-benefit ratio when machining medium to high-strength steel.

Simple system compatibility reduces setup uncertainty

Compatibility is determined by form, relief angle, tolerance class, mounting, size and thickness, so the ISO WNMG 080412 format integrates cleanly into standard tooling systems. The insert has a cylindrical hole for secure clamping and is intended to be used with a matching external holder or boring bar together with the appropriate backing plate and clamping set. This system approach enables predictable repeatability and simplifies inventory management for ISO-based tooling.

Robust geometry for stable cuts and surface quality

The NM chipbreaker is optimised for stable turning of steel and contributes to controlled chip formation in rigid set-ups. The geometry features a 0° rake angle and a 1.2 mm corner radius, balancing edge strength with achievable surface finish. With a plate thickness of 4.76 mm and an 80° trigon shape, the insert offers high rigidity for interrupted cuts and heavy cross sections, while maintaining good accessibility in shoulder and profile operations.

Consistent results and practical handling on the shop floor

Manufactured by Tungaloy to ISO dimensions, this insert provides repeatable performance across batches, supporting steady production planning. The standardised shape and mounting reduce changeover time, and the grade selection minimises the need for frequent retooling.

FAQ

What materials is this insert suitable for?
The WNMG080412-NM T9205 is designed primarily for productive turning of steel and performs best in stable machining conditions where higher cutting speeds are used.

What does the NM chipbreaker provide?
The NM chipbreaker on the WNMG080412-NM promotes stable chip control and consistent chip segmentation when turning steel, helping to protect the cutting edge and maintain surface quality.

Which holders are compatible with this insert?
Compatibility depends on form, relief angle, tolerance class, mounting, size and thickness; the ISO WNMG 080412 format fits all matching ISO WNMG holders and appropriate clamping sets with a cylindrical hole design.

How do the geometric values affect cutting performance?
The 0° rake angle and 1.2 mm corner radius increase edge strength for heavier cuts, while the 80° trigon shape and 4.76 mm thickness improve rigidity and stability for interrupted or shoulder turning.

How can batch and traceability be identified?
Identification is straightforward using the manufacturer article number 6785718 and the SKU 6785718-Tungaloy, which correspond to the WNMG080412-NM T9205 turning insert.
