TCMT110204‑RP4 WPP20G – Indexable insert for steel turning, triangle 60°, Walter Tools

TCMT110204‑RP4 WPP20G is an indexable turning and boring insert designed for efficient machining of steel (ISO group P) in general turning operations

• Tiger·tec Gold coated grade WPP20G
• Optimised RP4 chipbreaker for steel
• Triangle 60° insert, 0.4 mm corner radius
• 7° clearance angle for stable cutting

High productivity for steel machining with coated carbide

This insert combines a Tiger·tec Gold coated cemented carbide substrate with the WPP20G grade to deliver high process security when machining steel. The coated structure is designed to resist abrasive wear while maintaining edge stability, which translates into longer tool life and fewer interruptions in production. The RP4 chipbreaker specifically improves chip control in typical steel turning, reducing the need for complex chip evacuation measures. The measurable benefits are lower tooling costs per part and more consistent cycle times, making the insert suitable for demanding batch production and continuous operation environments.

Predictable cutting behaviour and surface quality

The triangular 60° geometry with a 0.4 mm corner radius and a 7° clearance angle delivers stable cutting forces and predictable deflection behaviour. These geometric parameters are chosen to balance strength and versatility: the small corner radius supports fine finishing without sacrificing edge robustness, while the clearance geometry reduces rubbing at the flank face. As a result, surface finish becomes more consistent and rework is reduced. For machinists seeking repeatable results on unalloyed and alloyed steels, the insert’s specification minimises variability between batches and supports tight process control.

Practical selection and application guidance for workshop use

The insert is coded as TCMT110204‑RP4 WPP20G, an industry-standard designation that facilitates toolholder matching and inventory management. The grade WPP20G is tuned for the heat and chip formation typical of steel machining and offers a compromise between wear resistance and toughness—suitable for general-purpose turning across a broad range of steel components. For best results, combine the insert with toolholders rated for triangle inserts and apply cutting data consistent with coated carbide recommendations for steel. Where unfamiliar alloys or special conditions exist, application testing and incremental feed optimisation are advisable to define the optimal parameters.

FAQ

Is this insert suitable for stainless steel?
The TCMT110204‑RP4 WPP20G is specified for steel (ISO group P); applicability to rostfreier Stahl (stainless steel) is not declared for this grade and should be verified with application trials or alternative grades.

What is the chip control capability of the RP4 breaker?
The RP4 chipbreaker on the TCMT110204‑RP4 WPP20G is optimised for the chip formation characteristics of steel, offering improved chip segmentation and evacuation under typical turning feeds and depths.

How does the Tiger·tec Gold coating affect tool life?
The Tiger·tec Gold coating applied to the WPP20G grade enhances wear resistance and edge stability during steel machining, resulting in extended tool life compared with uncoated carbide in comparable conditions.

Which toolholders are compatible with the TCMT110204‑RP4 insert?
Standard triangular indexable toolholders designed for TCMT‑type inserts are compatible; ensure correct clamping and seat geometry for secure mounting and repeatable indexation.

What performance can be expected in finishing operations?
With a 0.4 mm corner radius and the coated grade, the TCMT110204‑RP4 WPP20G can achieve consistent surface quality in finishing passes when combined with appropriate feed rates and cutting speeds for steel.
