TCMT090208-MP4 WPP20G turning/boring indexable insert by Walter Tools — Tiger·tec Gold coated, MP4 chipbreaker

TCMT090208-MP4 WPP20G is a coated carbide indexable insert designed for productive turning and boring applications in steel

• Tiger·tec Gold coated grade WPP20G
• Triangle 60° insert geometry
• MP4 chipbreaker for reliable chip control
• Corner radius 0.8 mm for finish turning

High-performance grade for robust production

The WPP20G grade, part of the Tiger·tec Gold family, provides a balanced combination of wear resistance and toughness for machining a wide range of steel grades. As a coated carbide solution, the insert reduces flank wear and extends edge life under typical turning loads; this leads to fewer index changes and improved overall tool economy. The specification supports operators and process engineers in maintaining consistent cycle times while protecting the cutting edge against thermal and mechanical stresses.

Geometry and chip former engineered for stable cutting

The triangle 60° insert geometry combined with the MP4 chipbreaker is aimed at promoting predictable chip formation and rapid evacuation in continuous and interrupted cuts. The modest corner radius of 0.8 mm helps achieve a fine surface finish without compromising strength at the cutting edge. A 7° clearance (free) angle reduces rubbing and minimises built-up edge, which in turn supports dimensional stability of the workpiece and repeatable surface quality during production runs.

Optimised for steel turning with consistent results

Classified for material group P, this insert is tailored to the heat and chip characteristics of unalloyed and alloyed steel. The tolerance class M and the plate form ensure compatibility with common turning toolholders using the TCMT090208 footprint, enabling quick replacement and short machine downtime. By selecting a grade designed for stability and a chipbreaker that controls swarf, the component enhances process reliability and supports higher productivity in batch and single-piece manufacturing environments.

FAQ

Which materials is this insert suitable for?
The TCMT090208-MP4 WPP20G insert by Walter Tools is specified for machining materials in the P group, i.e. unalloyed and alloyed steel, and its coating and grade are tuned to the typical heat and chip behaviour of steel.

How does the Tiger·tec Gold coating benefit performance?
The Tiger·tec Gold coating on the WPP20G grade enhances wear resistance and edge stability, which in practical terms reduces flank wear and extends life of the insert under steel turning conditions.

What is the role of the MP4 chipbreaker?
The MP4 chipbreaker is designed to control chip formation and evacuation, improving surface finish and preventing long, tangled swarf in both continuous cutting and light interruptions.

Is this insert compatible with standard TCMT090208 toolholders?
The insert follows the TCMT090208 geometry and is intended for use in standard toolholders that accept this indexable insert form, enabling straightforward replacement and re-indexing.
