WNMG100608-RP7 WPP20G – Trigon 80° indexable turning insert for steel, Tiger·tec Gold (Walter Tools)

A WNMG100608-RP7 WPP20G indexable turning insert engineered for steel turning, combining a Trigon 80° form with RP7 chip control and Tiger·tec Gold coated carbide

• Tiger·tec Gold coated carbide
• Trigon 80° geometry for robust cuts
• RP7 chipbreaker for stable chip control

Higher productivity through optimised coating and substrate

The combination of a Tiger·tec Gold coating and a coated carbide substrate delivers markedly improved wear resistance and thermal stability during steel machining. This design reduces flank and crater wear, which in turn maintains cutting performance over longer tool life cycles. The insert’s WPP20G grade is optimised for common steel grades (ISO group P), providing a balance between toughness and hardness that supports stable metal removal and fewer tool changes. For operations where cycle time and repeatability matter, the coated substrate offers a direct process advantage.

Predictable chip formation and surface integrity

Thanks to the RP7 chipbreaker and the Trigon 80° geometry, chip flow is stabilised across a range of feed rates and cutting depths. Stable chips reduce the risk of built-up edge and improve surface finish on the workpiece, which means fewer secondary operations. The 0° (negative) relief and a 0.8 mm corner radius contribute to robust edge strength for interrupted cuts or tough machining conditions. Together these features enable a consistent machining result and lower scrap rates in production environments.

Practical handling and compatibility for workshop use

The insert is supplied in the WNMG form factor with a thickness code of 06 and an insert size designation of 10, making it compatible with a wide range of standard turning toolholders designed for Trigon inserts. The tolerance class M ensures repeatable seating and stable clamping in the toolholder pocket. Because the grade is designed specifically for steel machining, operators and planners can expect straightforward application settings and predictable wear progression, simplifying tool management and inventory decisions.

Application pointers for efficient implementation

When integrating the insert into a process, favour cutting speeds and feeds aligned with steel machining best practices and verify coolant strategy for optimal heat control. The WPP20G grade performs well under conventional flood and high-pressure coolant conditions; however, settings should be validated on the specific steel alloy in use. Using the insert in a stable clamping setup and monitoring wear indicators will extend effective lifetime and contribute to more consistent component quality.

FAQ

What steels is this insert suitable for? The WNMG100608-RP7 WPP20G insert is formulated for steels (ISO group P) and performs well on a range of unalloyed and alloyed steels thanks to the Tiger·tec Gold coating.

How does the RP7 chipbreaker affect machining? The RP7 chipbreaker provides controlled chip formation, improving evacuation and reducing the risk of built-up edge, which enhances surface finish and process stability with this Walter Tools turning insert.

Can the Trigon 80° form be used for roughing and finishing? Yes, the Trigon 80° geometry combined with a 0.8 mm corner radius offers robustness for semi‑finishing and roughing; finishing performance depends on feed, depth of cut and machine rigidity.

Is the insert suitable for interrupted cuts? The negative 0° relief and robust corner radius give the insert high resistance to edge chipping, making it suitable for interrupted cuts and heavy engagement scenarios when used in a stable holder.

What toolholders are compatible with this insert? Standard toolholders designed for WNMG Trigon inserts accept the WNMG100608-RP7 WPP20G; ensure correct clamping and seat conditions to maintain tolerance class M performance.
