CCMT09T308-RM4 WMP20G — Rhombic 80° turning/boring insert, Tiger‑tec Gold (Walter Tools)

The CCMT09T308-RM4 WMP20G is a rhombic 80° indexable turning and boring insert designed for machining stainless steels under medium to robust conditions, featuring a Tiger‑tec Gold coated-carbide grade.

• Tiger‑tec Gold coating for high thermal resistance
• Optimised for stainless steel machining
• 0.8 mm corner radius for robust cutting edge

Longer tool life through advanced coating and grade selection

The combination of the WMP20G cutting grade and the Tiger‑tec Gold coating provides enhanced thermal and abrasive resistance compared with uncoated grades, which directly translates into longer tool life under the demanding conditions of stainless-steel turning. Coated carbide grades use thin, hard layers to reduce friction at the cutting zone and to delay flank wear; this improves process stability when machining materials that tend to work harden. The numerical features — 0.8 mm corner radius and 7° clearance — balance edge strength and allowable cutting parameters, giving a consistent compromise between robustness and achievable surface finish.

Stable chip control and fewer interruptions to production

The RM4 chipbreaker is engineered to produce controlled chip forms when tackling tough, ductile materials. Stable chip formation reduces the risk of built-up edge and interrupted cuts, which commonly cause scrap and additional finishing. By promoting short, manageable chips and predictable cutting forces, the insert supports higher machine uptimes and more reliable cycle times. In practice, improved chip control lowers the need for manual intervention and simplifies coolant and chip management strategies in the workshop.

Geometry and format that simplify tooling decisions

The rhombic Rhombus 80° geometry and the compact size specification (plate size 09, thickness T3) make the insert compatible with a wide range of standard turning and boring toolholders, reducing the number of special tool bodies required. The profile and corner radius are chosen to provide a robust cutting edge suitable for medium to heavy cuts while still allowing for acceptable surface integrity on the workpiece. For process planning, the insert’s defined parameters enable straightforward calculation of cutting data and easier comparison with alternative grades or geometries.
