VBMT110304-MM4 WMP20G – rhombic 35°, 5° clearance for stainless steel (Walter Tools)

The VBMT110304-MM4 WMP20G is a turning insert designed for medium to robust machining of stainless steel, offering optimised chip control and extended tool life in production environments.

• Tiger·tec Gold coating for enhanced wear resistance
• Optimised for stainless steel (ISO group M)
• Rhombic 35° geometry with 5° clearance
• MM4 chipbreaker for reliable chip control

Consistent edge life through advanced coating and chip control

The combination of Tiger·tec Gold coating and the MM4 chipbreaker provides measurable advantages in durability and process stability. The coating reduces flank and crater wear under elevated temperatures typical for stainless steel, while the chipbreaker promotes predictable chip formation, lowering the risk of built-up edge and unplanned tool changes. These technical measures translate into longer service intervals and fewer interruptions on the shop floor, supporting steady production throughput.

Geometry that improves cutting forces and surface quality

The rhombic 35° geometry with a 5° clearance reduces cutting forces in finish and semi-finish operations and helps to maintain tool engagement stability. A 0.4 mm corner radius balances edge strength and achievable surface finish, enabling controlled material removal without sacrificing component quality. Operators benefit from easier control of feed and depth, which supports consistent part tolerances and repeatable surface results.

Designed for efficient machining of ISO group M materials

Specified for ISO group M, the grade is tuned for the specific challenges of stainless steel, such as toughness and heat generation. The grade selection and chipbreaker configuration improve productivity by enabling higher cutting parameters where machine capability permits, while maintaining a stable cutting edge. This rational optimisation reduces overall machining time per part and contributes to a better cost-per-component metric in medium-duty to robust cutting scenarios.

Practical compatibility and secure handling in production

The insert follows common VBMT coding (size 11, thickness code 03) and is suitable for indexable systems that accept this form factor; this simplifies tooling logistics and spare-part management. As an indexable insert, it offers multiple cutting edges per item and fast replacement on standard toolholders, reducing downtime during changeovers. Backed by Walter Tools’ focus on precision and edge stability, the component supports reproducible performance across batches and shifts.
