CNMG120412-MP5 WPP10G – indexable turning insert, Tiger‑tec Gold grade for steel | Walter Tools

The CNMG120412-MP5 WPP10G is an indexable turning insert designed for reliable machining of steel, offering a negative 0° cutting geometry and a robust MP5 chipbreaker for consistent chip control in mixed production runs.

• Tiger‑tec Gold coating for high wear resistance
• Grade WPP10G optimised for steel machining
• MP5 chipbreaker for predictable chip formation
• Rhombic 80° shape with 1.2 mm corner radius

Boosted process reliability for steel turning

The coated Tiger‑tec Gold grade delivers a combination of wear resistance and toughness that translates into stable tool life during serial turning of steel. Thanks to the WPP10G carbide formulation and the MP5 chipbreaker, the insert reduces unexpected tool wear and supports consistent cycle times. The negative 0° geometry provides a secure cutting edge for interrupted cuts and heavy engagement, improving overall process predictability and reducing scrap rates.

Better chip control and surface quality

Optimised for the thermal and metallurgical behaviour of steels, the insert’s MP5 chipbreaker promotes short, controllable chips and reduces the risk of built-up edge. This leads to improved surface finishes and fewer secondary operations. The Rhombus 80° form allows versatile approach angles, while the 1.2 mm corner radius balances strength and edge form to maintain dimensional accuracy across repeated passes.

Versatile format that simplifies tooling management

The CNMG form factor with its standard ISO designation and the clearly defined 04 thickness class offers compatibility with a wide range of toolholders, enabling easier stocking and tool changeovers. The insert’s universality for steels lowers the number of grades required in the tool crib and supports flexible process planning. For mixed-lot production where consistent performance matters, the blend of coating, grade and chip control contributes to measurable productivity gains.

FAQ

What materials is this insert intended for?
The CNMG120412-MP5 WPP10G insert is designed primarily for machining steel and is classified for P‑group materials according to ISO recommendations.

How does the MP5 chipbreaker help in production?
The MP5 chipbreaker on the WPP10G grade promotes predictable chip formation and short chips, improving surface finish and reducing manual chip management during turning operations.

What does the Tiger‑tec Gold coating provide?
The Tiger‑tec Gold coating enhances wear resistance while maintaining edge toughness, extending tool life under the thermal loads typical of steel cutting.

Is the negative 0° geometry suitable for interrupted cuts?
Yes; the 0° negative geometry offers increased edge strength and stability, making the insert suitable for interrupted cuts and heavier depth of cut applications.

What does the CNMG120412 designation indicate?
The ISO code CNMG120412 identifies the insert form (rhombic 80°), size class (12) and corner radius (1.2 mm), together with the MP5 chipbreaker specification.
