SCMT120408-FP4 WPP20G indexable turning insert — Walter Tools, Tiger·tec Gold for steel machining

The SCMT120408-FP4 WPP20G is a square 90° indexable turning insert with a 7° relief angle, engineered for productive steel turning operations.

• Tiger·tec Gold coated grade WPP20G
• Square 90° insert with 0.8 mm radius
• FP4 chipbreaker for stable chip control
• Designed for machining steel (ISO P)

Greater productivity through durable cutting performance

The coated carbide of the Tiger·tec Gold family combines a wear-resistant surface with a substrate engineered for toughness, providing a balanced mix of wear resistance and edge stability. This results in fewer tool changes and longer uninterrupted cutting time, which in turn improves process efficiency on production lines. The insert’s coated grade is optimised for the thermal and mechanical conditions encountered when machining steel, so users benefit from consistent dimensional accuracy and reduced downtime when switching batches or workpiece types.

Stable chip formation and improved surface finish

The FP4 chipbreaker is designed to control chip formation under typical steel cutting regimes, reducing the risk of entangling long chips and improving evacuation. Controlled chips lead to safer machining and fewer secondary operations for chip handling. Together with the square 90° geometry and a 0.8 mm corner radius, the insert supports predictable cutting forces and a fine surface quality, which helps achieve tighter tolerances and reduces the need for finishing passes.

Application adaptability that supports process reliability

Rated for ISO P materials, the grade provides a versatile solution across a wide range of steel grades, from general-purpose to tougher alloys. The 7° relief angle reduces rubbing on the workpiece and aids in stable cutting at moderate feeds, offering a reliable compromise between strength and cutting performance. For manufacturers prioritising repeatable production outcomes, the insert’s combination of geometry and grade promotes consistent cycle times and predictable tool life.

Integration into machining workflows and handling benefits

The familiar SCMT format and square form make the insert straightforward to index and replace, simplifying inventory management and operator training. Marked tolerance class M ensures consistent fitment in compatible toolholders, while the plate thickness and geometry deliver mechanical rigidity for interrupted cuts or heavier engagement. Clear specification and compatibility with standard toolholders reduce setup time and support faster changeovers in serial machining environments.
