TNMM270616-HU7 WPP20G turning insert (Triangle 60°, r1.6) — Walter Tools

The TNMM270616-HU7 WPP20G is a triangular indexable turning insert for steel machining, combining the Tiger‑tec Gold coating with an HU7 chipbreaker for consistent chip control and extended tool life.

• Tiger‑tec Gold coating for enhanced wear resistance
• Optimised HU7 chipbreaker for reliable chip control
• Triangle 60° form for stable insert seating
• Corner radius 1.6 mm for robust cutting edge

Greater throughput with a wear-resistant cutting grade

The coated carbide technology Tiger‑tec Gold paired with the WPP20G grade focuses on extending tool life and sustaining cutting performance in demanding steel applications. The coating reduces flank wear and improves resistance to abrasive and adhesive mechanisms that shorten tool life; as a result, cycle times can be increased while maintaining dimensional stability. The HU7 chipbreaker is designed to manage chips typical of ISO group P (steel), which means more predictable swarf behaviour and fewer interruptions for chip removal. These technical choices translate directly into measurable efficiency gains on the shop floor and reduced tooling costs per component.

Predictable process reliability through geometry and edge strength

Mechanical stability stems from the insert geometry: the triangle 60° form provides three usable cutting edges per indexation and a secure seat in standard triangular toolholders, while the corner radius 1.6 mm supports robust edge strength for interrupted cuts and higher feed rates. The 0° negative rake indicated for this insert favours heavy‑cut operations and reduces the risk of edge chipping when forces are high. Together, these characteristics enable a repeatable process window and improve first‑part accuracy—important for batch production where consistency is critical.

Practical selection and machining guidance for steel applications

The cutting grade and chipbreaker are optimised for unalloyed and alloyed steel according to ISO group P. When selecting cutting parameters, start from conservative speeds and feeds recommended for coated carbide in steel and increase speed until tool‑life or surface finish objectives are met. The combination of Tiger‑tec Gold coating and the HU7 chipbreaker favours medium to high cutting speeds with stable chip segmentation. For special steels, high alloy content, or unusual geometries, seek customised feed and speed recommendations to exploit the insert’s balance of wear resistance and toughness—Metav Werkzeuge can assist with cutting data sheets and trial‑cut guidelines.

FAQ

Which materials is this insert suitable for?
The TNMM270616-HU7 WPP20G is specified for ISO group P—primarily unalloyed and alloyed steel—and the grade and chipbreaker are optimised for the heat and chip characteristics of these materials.

What does the WPP20G cutting grade offer?
WPP20G is Walter Tools’ coated carbide grade within the Tiger‑tec Gold family, engineered to balance wear resistance and toughness for productive steel machining.

How does the HU7 chipbreaker affect chip control?
The HU7 chipbreaker produces short, controllable chips when cutting steel, improving swarf evacuation and reducing the risk of entanglement in typical turning operations.

Can this insert be used for stainless steel or hardened materials?
Stainless steel and hardened materials are not listed among the specified applications for this insert; the TNMM270616-HU7 WPP20G is optimised for steel. For other material groups, consult Metav Werkzeuge for alternative grades and geometries.

What cutting geometry is required in the toolholder?
A triangular 60° seat suitable for TNMM‑style inserts is required; the form provides stable seating and three indexable edges for economical use.
