CNMQ120608T-A27T WKP35S Fräswendeschneidplatte by Walter Tools — Rhombus 80°, negative relief 0°

CNMQ120608T-A27T WKP35S Fräswendeschneidplatte is a coated carbide cutter insert designed for productive milling of steel and cast iron components

• Tiger·tec Silver coating technology
• WKP35S grade for steel and cast iron
• Rhombic 80° geometry with 0° relief
• Corner radius 0.8 mm for robust cutting edges

Exceptional productivity for steel and cast iron machining

The combination of the Tiger·tec Silver coating and the WKP35S grade provides a balanced mix of wear resistance and reliable cutting-edge stability, optimised for the typical heat and chip characteristics of steel (ISO group P) and the abrasive, breaking-chip behaviour of cast iron (ISO group K). The coated carbide construction ensures reduced flank wear over repetitive cycles, translating into longer tool life and fewer indexings compared with uncoated solutions. The rhombic 80° form together with the negative relief 0° supports secure clamping and repeatable positioning in standard milling cutters, which benefits batch production where consistent part quality is essential. Explanations of terms: coated carbide describes a hardmetal body with a thin, engineered surface layer that improves thermal resistance and reduces abrasive wear during milling.

Consistent surface finish and chip control for stable processes

The plate’s corner radius 0.8 mm and the A27T chipbreaker geometry are selected to deliver stable chip formation and improved surface integrity, particularly in medium-depth finishing passes. A controlled chip shape reduces the risk of recutting and protects the tool edge from sudden load peaks, which is important for maintaining cycle times and reducing scrap rates. The WKP35S grade, as part of the Tiger·tec Silver series, is formulated to offer good resistance against flank and crater wear while preserving edge toughness — a combination that supports both long tool life and repeatable dimensional results in serial production environments.

Practical handling and integration into existing tool systems

The insert designation CNMQ120608T-A27T makes the mounting and replacement process straightforward in compatible indexable cutter bodies. The standardised rhombus form and the M tolerance class enable predictable seating and minimal rework during changeovers. For workshops aiming to increase uptime, the reliable chip control and the stable cutting edge reduce the frequency of tool changes and the need for extensive rework, thereby lowering total machining cost per part. For application selection, the grade is catalogued against ISO groups P and K, which guides tool path planning and feeds/speeds adjustments in CAM systems.
