TCMT220408-MP4 WPP20G — turning indexable insert (steel) by Walter Tools

A TCMT220408-MP4 WPP20G turning insert designed for reliable steel machining with a Tiger·tec Gold coated grade, MP4 chip control and triangle 60° geometry for versatile turning operations

• Tiger·tec Gold coating for improved tool life
• Grade WPP20G optimised for steel machining
• Triangle 60° insert with 0.8 mm corner radius
• MP4 chipbreaker for reliable chip control

Consistent cutting performance for steel applications

The Tiger·tec Gold coating combined with the WPP20G grade is formulated specifically for P‑group materials, meaning it is optimised for unalloyed and alloyed steel. This results in stable chip formation and reduced flank wear under typical steel turning temperatures. For production environments this translates into fewer indexings per workpiece and more predictable tool life, improving overall machining efficiency. The coating also helps to resist built‑up edge and maintain performance across varied cutting conditions.

Geometry designed for repeatability and surface quality

The triangular 60° shape and 0.8 mm corner radius provide a balance between strength and surface finish. The 7° relief angle reduces rubbing and heat generation at the cutting edge, while the tolerance class M supports consistent seating in toolholders for repeatable results. These geometry choices enhance process stability and make this insert suitable for a wide range of turning operations where dimensional consistency and good surface integrity are required.

Chip control that keeps machines productive

The integrated MP4 chipbreaker is engineered to produce controlled, short chips in turning of steel grades, minimising the risk of entanglement and improving swarf evacuation. Reliable chip formation reduces secondary operations such as manual chip clearing and lowers the likelihood of machine stoppages, supporting higher uptime and a steadier machining flow. For operations seeking measurable gains in productivity, the chip control is a practical contributor to reduced cycle times.

Practical mounting and grade clarity for workshop use

Identified as a TCMT220408-MP4 insert, the format aligns with common turning toolholder systems, enabling straightforward replacement and stock keeping. The grade designation WPP20G signals a coated cemented carbide tailored to steel applications and is part of the Tiger·tec Gold series; this clarity simplifies grade selection for production planners. The insert’s design encourages short changeover times and predictable inventory management, aiding continuous production planning.
