TCMT16T304-RP4 WPP20G – Triangle 60° indexable insert with Tiger·tec Gold coating by Walter Tools

The TCMT16T304-RP4 WPP20G is a triangle 60° indexable insert for turning and boring, engineered for high-performance machining of steel components.

• Tiger·tec Gold coated carbide grade WPP20G
• RP4 chipbreaker for controlled chip formation
• Triangle 60° form for versatile turning
• 0.4 mm corner radius, 7° relief angle

Reliable performance for steel machining

The insert combines a coated carbide substrate with Walter Tools’ Tiger·tec Gold technology to deliver consistent edge life when machining steels (material group P). The WPP20G grade is formulated for the typical heat and chip-formation behaviour of steel, offering a balanced mix of wear resistance and toughness. In practice, this means fewer interruptions for tool changes, more predictable tool costs and a stable process window for medium to high cutting speeds. The technical design supports repeatable part quality and helps to maintain cycle time targets.

Geometry that stabilises cutting and improves finish

A triangular 60° shape with a 0.4 mm corner radius and a 7° relief angle provides a robust cutting edge and good strength in interrupted cuts. The RP4 chipbreaker is designed to control chip flow reliably across a range of feeds, breaking chips into manageable segments and reducing the risk of tangling or surface damage. For operators less familiar with chipbreaker design: the RP4 groove redirects and compresses the chip to encourage short, controllable chips, which simplifies swarf handling and reduces contaminant-related surface marks.

Shop-floor advantages and process gains

The insert’s T3 thickness and tolerance class M contribute to secure clamping and long-term repeatability in toolholders that accept the TCMT format. Stable clamping, combined with the grade’s wear resistance, reduces downtime and increases average tool life, yielding lower cost per component. Improved chip control from the RP4 geometry lowers manual cleaning and handling time, while the triangular form offers three usable cutting edges, extending service intervals and improving overall productivity in batch and single-piece production alike.

Flexible integration and application scope

Designed primarily for steel applications (ISO group P), this indexable insert suits a wide variety of turning and boring tasks where a balance of productivity and surface quality is required. The WPP20G grade is a universal choice within the Tiger·tec Gold family, enabling consistent results across commonly used steels without the need for frequent grade swaps. As a Walter Tools product, the insert benefits from a development focus on process stability and reproducible tool life, making it suitable for both jobbing shops and production lines that demand dependable performance.

FAQ

Which materials is this insert suitable for?
The TCMT16T304-RP4 WPP20G insert is designed primarily for machining steel (ISO group P); the WPP20G grade is optimised for the heat and chip-formation typical of steel.

How does the RP4 chipbreaker affect machining?
The RP4 chipbreaker on the TCMT16T304-RP4 WPP20G produces short, controlled chips that simplify swarf handling and reduce surface contamination, improving process reliability.

Is the triangular form suitable for heavy-duty cuts?
The triangle 60° form with a 0.4 mm corner radius provides a robust edge for many turning and boring operations; the insert supports interrupted and steady cuts with a favourable balance of strength and edge life.

Can this insert be used in standard TCMT toolholders?
Yes, the TCMT16T304-RP4 WPP20G follows the TCMT format and is compatible with toolholders designed for that insert designation, offering three indexed cutting edges for extended service.
