VCMT110308-RP4 WPP20G — Turning indexable insert with Tiger‑tec Gold coating, RP4 chipbreaker — Walter Tools

A VCMT110308-RP4 WPP20G turning indexable insert engineered for robust, productive machining of steel components in general and precision turning operations

• Tiger‑tec Gold coated carbide for robust wear resistance
• Optimised RP4 chipbreaker for reliable chip control
• Rhombic 35° shape with 7° clearance angle
• 0.8 mm corner radius for consistent surface finish

Extended tool life through advanced coating and substrate

The combination of the Tiger‑tec Gold technology and a coated carbide substrate provides a balanced mix of hardness and toughness that is optimised for steel machining. This grade is designed to resist abrasive wear while maintaining a stable cutting edge under the thermal loads typical of P‑group materials. The result is improved wear resistance and fewer unexpected tool changes, which supports uninterrupted production and predictable tooling costs. The specification supports repeatable performance in serial production and helps maintain component tolerances over longer tool lives.

Geometry designed for stable cuts and accurate finishes

The insert’s geometry — a rhombic 35° form with a 7° clearance angle and a 0.8 mm corner radius — delivers consistent contact conditions and controlled chip formation. The RP4 chipbreaker is optimised to break and evacuate chips reliably during a range of feeds and depths, reducing the risk of long, entangling chips and enhancing surface quality. These geometric choices mean fewer secondary operations and reduced operator intervention, producing a steady surface finish and dimensional consistency in turning operations.

Process efficiency: productivity and predictable results

By focusing on wear stability and dependable chip control, the insert supports higher machine utilisation and lower per‑part tooling costs. The insert’s balance of toughness and hardness helps to avoid premature chipping on interrupted cuts and to sustain cutting edge integrity during longer cycles. Improved process security and reduced downtime translate into measurable productivity gains for medium to large batch production. For machining shops aiming to streamline throughput, this insert contributes to a more efficient production flow and fewer unplanned tool changes.

Application scope and practical guidance

The grade is intended primarily for the machining of steel (ISO P group), covering both unalloyed and alloyed steels encountered in general turning. The designation and form factor make the insert suitable for a wide range of finishing and medium turning tasks where surface quality and dimensional control are important. For specific cutting speeds, feeds and depth‑of‑cut recommendations for particular steels or toolholders, Metav Werkzeuge’s technical advisors can supply validated data and pairing suggestions to match the insert to the machine and the holder.

FAQ

What materials is this insert intended for? The WPP20G grade is optimised for machining steel (ISO P group); the VCMT110308-RP4 WPP20G insert from Walter Tools is specified for unalloyed and alloyed steels used in general turning.

What is the corner radius and how does it affect surface finish? The insert features a 0.8 mm corner radius, which offers a compromise between strength and finish: it supports a smooth surface at finishing feeds while providing sufficient edge strength for interrupted cuts.

Which chipbreaker is fitted and what benefit does it provide? The RP4 chipbreaker on this insert is designed for reliable chip segmentation and evacuation during a range of feeds, improving process stability and reducing the risk of chip entanglement.

Can this insert be used for stainless steel or other non‑ferrous materials? The supplied data specifies suitability for steel (ISO P). There is no designation in the data for stainless steel or non‑ferrous materials, so confirmation should be sought if machining those materials is required.

Where can cutting parameters and holder recommendations be obtained? For validated cutting data, holder pairing and application guidance for the VCMT110308-RP4 WPP20G turning insert by Walter Tools, contact Metav Werkzeuge’s technical team for tailored recommendations.
