Rhombic 80° shape for versatile turning applications
11° relief angle and 0.8 mm corner radius

Productive machining of Stahl with a coated grade

The combination of the WPP20G grade and the Tiger·tec Gold coating targets the thermal and mechanical demands of machining Stahl. Designed for typical heat generation and chip formation when cutting unalloyed and alloyed materials of ISO group P, this coated carbide delivers predictable wear behaviour. The result is improved process stability and fewer unexpected tool changes, which supports continuous production and reduces overall machining interruptions.

Greater durability and lower tooling cost per part

The surface treatment and substrate selection provide enhanced resistance to abrasive and adhesive wear. With the Tiger·tec Gold technology, flank and crater wear are delayed, extending the effective life of the insert and lowering the cost per component. This means longer intervals between indexings and replacements, contributing to measurable savings on repeat operations and increasing machine availability across production shifts.

Geometry that secures surface finish and chip evacuation

The MP4 chipbreaker, in conjunction with the rhombic 80° form and a 0.8 mm corner radius, produces controlled chip segmentation and redirection away from the cutting zone. The 11° relief angle reduces rubbing on the flank face and supports a cleaner cutting action. Together these geometry elements enhance surface integrity and reduce built-up edge, which is especially advantageous during medium to heavy cuts in diverse Stahl grades.

Integration into turning processes and recommended use

The insert designation CPGT09T308-MP4 identifies a compact plate with a T3 thickness and a size corresponding to 09, making it suitable for a wide range of toolholders that accept this geometry. As a member of the Tiger·tec Gold series, the CPGT09T308-MP4 WPP20G insert is primarily specified for Stahl applications and offers a balance between wear resistance and toughness for reliable performance in production turning.

FAQ

What materials is this insert designed for?
The CPGT09T308-MP4 WPP20G insert is specified for machining materials in ISO group P and is optimised for Stahl applications, covering a wide range of unalloyed and alloyed steels.

How does the MP4 chipbreaker affect cutting performance?
The MP4 chipbreaker promotes reliable chip segmentation and evacuation, improving process stability and helping to maintain consistent surface finish during medium to heavy turning operations.

Which geometry features support surface quality?
The combination of the rhombic 80° shape, 0.8 mm corner radius and 11° relief angle reduces flank contact and supports a steady cutting action, which contributes to improved surface integrity.

Is the Tiger·tec Gold coating suitable for high-temperature cutting conditions?
Yes, the Tiger·tec Gold coating is developed to withstand the thermal and mechanical stresses typical in turning Stahl, delaying wear mechanisms and extending service life.

What does the designation CPGT09T308-MP4 indicate?
The code denotes the insert family, size (09), thickness (T3), geometry (rhombic 80° with 0.8 mm corner radius) and the MP4 chipbreaker; combined with the grade WPP20G it provides a clear specification for tool selection.
