SNMG120408‑RP7 WPP20G indexable turning insert — Tiger‑tec Gold, for steel

The SNMG120408‑RP7 WPP20G is a square 90° indexable turning insert with a Tiger‑tec Gold coated carbide grade, optimised for machining steel in stable, productive turning operations.

• Tiger‑tec Gold coated grade WPP20G
• Square 90° insert, 0.8 mm corner radius
• RP7 chipbreaker for reliable chip control
• Negative 0° clearance for robust cutting

Productive steel turning with a coated, versatile grade

The coated carbide WPP20G grade, developed within the Tiger‑tec Gold family, is designed for the thermal and chip-formation conditions typical of steel machining (ISO P). The coating and substrate combination increase wear resistance and maintain a stable cutting edge under variable cutting conditions, resulting in longer productive tool life and fewer insert changes during batch runs. For manufacturing environments that prioritise throughput and repeatability, this insert reduces process interruptions while delivering consistent component tolerances.

Stable chip control and stronger cutting edges for secure turning

The RP7 chipbreaker is engineered to produce segmented chips and controlled chip flow when machining steels, which lowers the risk of entanglement and workpiece damage. Combined with the square (90°) geometry and a 0.8 mm corner radius, the insert provides enhanced edge support and robustness in interrupted cuts or heavy cuts. The negative 0° clearance improves resistance to edge chipping and is beneficial where rigidity and edge strength are required, giving a reliable solution for medium to demanding turning operations.

Designed for production use with consistent results

With a focus on process stability and economical performance, this indexable insert is suitable for serial production and general turning tasks in job shops and industrial workshops. The medium tolerance class contributes to predictable fitment in standard SNMG toolholders and repeatable positioning. By selecting a coated grade optimised for steel and a chipbreaker matched to common turning chip shapes, machinists gain a balance of surface quality and tool life that helps to lower overall machining costs and increase uptime.

FAQ

What materials is this insert suitable for?
The SNMG120408‑RP7 WPP20G is specifically formulated for steel machining (ISO P); the WPP20G grade and Tiger‑tec Gold coating address the heat and chip-formation typical of steel turning.

How does the RP7 chipbreaker benefit production turning?
The RP7 chipbreaker on this insert promotes segmented, controllable chips and reliable chip evacuation, improving safety and reducing the need for secondary chip handling during continuous production.

What does the 0.8 mm corner radius mean for edge strength and surface finish?
A 0.8 mm corner radius increases edge support and resistance to chipping while delivering a good balance between tool strength and achievable surface finish in general turning operations.

Is the negative 0° clearance suitable for interrupted cuts?
Yes; the negative 0° clearance enhances edge stability and resistance to impact, which is advantageous in interrupted cuts and heavy-duty machining scenarios.

Can this insert be used in standard SNMG toolholders?
The insert conforms to the SNMG geometry designation and is intended for standard indexable turning setups compatible with SNMG‑type inserts.
