TNMG220408-RP5 WPP30G triangle 60° turning insert, Tiger‑tec Gold coating — Walter Tools

TNMG220408-RP5 WPP30G is a triangular turning insert engineered for productive machining of steel components, offering a negative 0° rake and a 0.8 mm corner radius for stable performance.

• Tiger‑tec Gold coating for long tool life
• RP5 chipbreaker for controlled chips
• Triangle 60° form for versatile turning
• Negative 0° rake for robust cutting

Higher throughput for steel turning with proven coating technology

The combination of Tiger‑tec Gold and a coated carbide substrate delivers a balance of wear resistance and toughness that benefits production environments machining steel. The designed coating system reduces flank wear and extends tool life, enabling fewer insert changes and more uninterrupted machining time. The insert geometry supports stable heat management during typical steel cutting cycles, which translates into more predictable process windows and consistent part quality.

Controlled chip formation and surface integrity with RP5

The RP5 chipbreaker is optimised for typical steel chip shapes and evacuation, reducing secondary operations and minimising entanglement. A well-controlled chip flow decreases the risk of workpiece damage and supports improved surface quality without compromising cutting stability. The insert’s triangular 60° form, together with the 0.8 mm nose radius, achieves a compromise between fine surface finish and sufficient edge strength for medium to heavy cuts.

Robust geometry for demanding turning tasks

A negative 0° rake provides a mechanically stronger cutting edge where interrupted cuts or heavy depths of cut are required. The insert’s construction ensures reliable seating in standard toolholders while the specified tolerance class M supports consistent repeatability in production. These design choices favour shops prioritising process reliability and predictable consumable behaviour under varying load conditions.

Compatibility, selection and application guidance

The insert is intended for machining materials classified in group P (general steel grades) in accordance with ISO guidance. Selection of cutting data should consider material condition, machine rigidity and coolant usage; the Tiger‑tec Gold grade is suited to a broad range of steel alloys and cutting regimes. For integration into existing tool systems, the triangular shape and TNMG style make the insert compatible with widely used turning toolholders; recommended feeds and speeds vary with workpiece material and diameter.

FAQ

Is this insert suitable for general steel turning?
The TNMG220408-RP5 WPP30G is specifically designed for machining materials in ISO group P (steel), providing good resistance to the heat and chip formation typical of steel turning.

What is the purpose of the RP5 chipbreaker?
The RP5 chipbreaker promotes stable chip formation and evacuation during steel cuts, helping to protect the workpiece surface and reduce manual chip management.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm nose radius improves edge strength and contributes to a balanced surface finish; it is suitable for medium to heavy cuts while still supporting acceptable finish quality.

Can the insert handle interrupted cuts or heavy depths of cut?
The negative 0° rake geometry strengthens the cutting edge, making the insert resilient under interrupted cutting and heavier engagement typical in robust turning applications.
