Increased productivity through Tiger·tec Gold coating

The coated carbide grade from the Tiger·tec Gold series provides a measurable increase in tool life and process stability in demanding milling operations. The WKP35G grade is a coated carbide formula optimised for the thermal and mechanical loads typical when machining steels and cast irons; this reduces flank wear and supports longer uninterrupted cutting cycles. The coating improves resistance to abrasive wear and helps maintain a reliable cutting edge, which in turn lowers tool-change frequency and contributes to a more efficient production flow.

Consistent chip formation and secure cutting performance

The insert’s chipbreaker F57T and the 0° negative rake work together to produce predictable chip shapes under heavy cutting conditions, particularly in interrupted cuts or when removing large material volumes. A stable chip formation reduces the risk of workpiece damage and improves machine uptime. The combination of the chip control geometry and the grade’s wear characteristics results in a balance between high material removal rates and consistent surface quality, making the insert suitable for series production where repeatability matters.

Geometry tuned for repeatable clamping and surface quality

The rectangular form and a 0.8 mm corner radius provide a strong cutting edge and help resist edge chipping in roughing operations. The negative rake angle increases edge strength for tougher cuts, while the tolerance class H supports consistent seating in standard toolholders. These geometric choices contribute to predictable tool behaviour and make process setup simpler: stable clamping and repeatable positioning reduce the need for frequent re-adjustment, which is particularly valuable in mixed-batch environments and automated cells.

Material applicability and process guidance

Classified for ISO material groups P and K, the insert is intended primarily for unalloyed and alloyed steel as well as cast iron, where its abrasion resistance and chip control are advantageous. The grade’s technical balance suits a range of cutting conditions; for customers less familiar with grade selection, guidance on cutting speeds, feeds and coolant strategies will ensure economical performance. The insert’s coated carbide construction and chipbreaker geometry are particularly effective where heat and intermittent cutting threaten tool life, translating into lower overall tooling costs per finished part.

FAQ

What materials is this insert suitable for?
The LNHU100508-F57T WKP35G insert is intended for steel (ISO group P) and cast iron (ISO group K) machining, with the WKP35G grade optimised for those material families.

How does the 0° negative rake influence performance?
A 0° negative rake increases cutting-edge strength and supports heavier cuts; in the LNHU100508-F57T WKP35G this contributes to robust performance during roughing and interrupted cuts.

What benefit does the Tiger·tec Gold coating provide?
The Tiger·tec Gold coating on this grade reduces abrasive wear and improves thermal resistance, extending usable tool life and stabilising surface finish over longer cycle times.

Is the insert suitable for finishing operations?
While the geometry and grade favour productivity and edge strength, controlled cutting parameters and appropriate feed rates with this insert can achieve acceptable finishing results; select cutting data according to the workpiece and machine rigidity.

Which chipbreaker is fitted and what does it do?
This insert features the F57T chipbreaker, designed to promote predictable chip formation under heavy and interrupted cutting, improving material evacuation and process reliability.
