LNMU160812-F57T WPP35G milling insert, Tiger·tec Gold coated, for steel – Walter Tools

The LNMU160812-F57T WPP35G is a rectangular indexable milling insert engineered for efficient machining of steel under continuous production conditions

• Tiger·tec Gold coating for extended tool life
• Optimised F57T chipbreaker for steel machining
• Rectangular form with 1.2 mm corner radius
• Negative 0° rake for stable cutting

Enhanced wear resistance and consistent cutting performance

The combination of a Tiger·tec Gold coating and a coated carbide substrate offers a clear advantage where repeatable performance is required. The surface engineering reduces abrasive wear and helps maintain edge stability during extended cycle times, which translates into longer periods between index changes. With the built-in chipbreaker F57T, chip formation and evacuation are improved for typical steel chips, reducing rework and downtime while increasing overall process reliability.

Balanced grade for steel applications and predictable results

The WPP35G grade is purpose-developed for ISO P materials and provides a balanced compromise between wear resistance and toughness. This makes the insert suitable for a broad range of steel tasks where moderate to high cutting forces occur. The specification emphasises constant results and predictable tool life, so production planning and cost-per-part calculations become more dependable when the insert is used in a matched toolholder and cutting data are applied correctly.

Geometry designed for secure machining and easy integration

With a corner radius of 1.2 mm and a rectangular plate form, the insert supports robust engagement and good edge strength for interrupted or continuous cuts. The negative 0° rake increases stability at the cutting edge and reduces the risk of chipping under heavy loads. The nominal insert dimensions (16 mm length, 0.8 mm thickness) and ISO-based designation make it straightforward to select compatible toolholders that accept LNMU-style inserts, simplifying tool inventory management and changeover.

FAQ

Which materials is this insert suitable for?
The insert is intended for ISO P materials; it is optimised for steel machining and was developed to manage the heat and chip behaviour typical for steels.

What are the key geometry values and their effect?
A corner radius of 1.2 mm and a negative 0° rake enhance edge strength and stability during load changes; these values support secure machining and predictable tool life.

Can the insert be used for both roughing and semi-finishing operations?
Yes, the WPP35G grade balances wear resistance and toughness, making the insert appropriate for a range of operations from roughing to semi-finishing in steel applications.

Does the LNMU160812-F57T fit standard toolholders?
The LNMU designation corresponds to a common insert form; it fits toolholders designed for LNMU-style rectangular inserts, allowing easy integration into existing tooling systems.

What benefits does the Tiger·tec Gold coating provide?
The Tiger·tec Gold coating reduces abrasive wear and improves edge resilience, which contributes to longer service intervals and more consistent component quality.
