LNHU120608-B57T WPP35G – rectangular milling insert, Tiger·tec Gold, Walter Tools

The LNHU120608-B57T WPP35G is a rectangular indexable insert designed for efficient steel machining with Tiger·tec Gold coating for high wear resistance.

• Tiger·tec Gold coating WPP35G for steel machining
• Rectangular insert with 0° negative rake
• Corner radius 0.8 mm for robust edge strength
• Chipbreaker B57T for controlled chip formation

Consistent performance for steel production

The combination of the WPP35G grade and the Tiger·tec Gold coating delivers wear resistance and consistent cutting behaviour in ISO P applications (steel). The coated carbide substrate is engineered to manage the heat and chip formation typical for steel machining; this means fewer insert changes and more predictable cycle times. For production environments where component repeatability matters, the insert’s material pairing and coating technology contribute to steady tool life and reduced scrap rates, improving overall process efficiency.

Robust geometry that protects the cutting edge

A rectangular shape combined with a 0° negative rake and a 0.8 mm corner radius enhances edge stability under interrupted cuts and higher feed rates. Negative rake geometry increases edge strength and reduces the risk of chipping during heavy cuts, while the modest corner radius balances durability with achievable surface quality. The tolerance class H supports consistent seat fitment and repeatable positioning in toolholders, ensuring the insert performs reliably across batch runs.

Controlled chips and improved surface finish

The B57T chipbreaker is designed to direct and break chips effectively when machining steels, reducing entanglement and promoting safe evacuation from the cutting zone. Better chip control lowers thermal load on the tool and workpiece, which in turn helps maintain dimensional accuracy and surface finish. For users transitioning from common grades, the Tiger·tec Gold finish and chip geometry give an immediate uplift in process stability and fewer interruptions, making the tool suitable for both roughing and mixed finishing tasks.

Ready integration and clear specification for selection

Available as a 12 mm rectangular insert with thickness code 06 and the ISO designation LNHU120608-B57T WPP35G, the insert fits standard Walter toolholders that accept this format. The grade is tailored to the steel material group (P), giving a broad application range from general-purpose to more wear-demanding operations. When choosing cutting parameters, prioritise stable feeds and sufficient coolant or lubrication for steel to exploit the grade’s optimised wear characteristics; this approach yields economical machining through extended time between indexings.

FAQ

What materials is this insert suitable for?
The LNHU120608-B57T WPP35G is specified for ISO P applications and is intended primarily for machining steel; the WPP35G grade and Tiger·tec Gold coating are optimised for steel-specific heat and chip conditions.

How does the B57T chipbreaker improve machining?
The B57T chipbreaker on the LNHU120608-B57T promotes predictable chip formation and breakage, reducing chip congestion and lowering thermal load on the cutting edge while supporting consistent surface quality.

Is the insert suitable for roughing and finishing operations?
Yes—the insert’s 0.8 mm corner radius and negative 0° rake give edge robustness for roughing while still allowing acceptable surface quality in semi-finishing with appropriate cutting data.

What benefits does Tiger·tec Gold provide?
Tiger·tec Gold coating on the WPP35G grade increases wear resistance and offers better process stability, which typically extends tool life and reduces the frequency of index changes in steel machining.
