DNMG150608-MM5 WMP20S turning insert — Tiger·tec Silver grade for stainless steel, negative 0° rake

The DNMG150608-MM5 WMP20S is a rhombic 55° indexable turning insert designed for dependable stainless-steel machining under medium to robust conditions

• Tiger·tec Silver grade for stainless steel
• MM5 chipbreaker for stable chips
• Rhombic 55° geometry for versatile turning
• Negative 0° rake for strong cutting edge

High-performance coating and substrate for tough materials

The insert features the Tiger·tec Silver specification and the WMP20S cutting grade, a coated carbide combination optimised for machining stainless steel. This construction supports secure chip formation and reduces the tendency to build up on the cutting edge — a common challenge with austenitic stainless grades. The coating enhances thermal stability and wear resistance, which translates into fewer interruptions for tool changes and more predictable cycle times. The technical choice of substrate and coating therefore underpins measurable process reliability during extended production runs.

Geometry and chip control that improve productivity

With a rhombic 55° shape, a 0.8 mm corner radius and an MM5 chipbreaker, the insert is engineered for a balance between surface finish and edge robustness. The negative 0° rake delivers a stronger cutting edge, making the insert suitable for heavier depths of cut and interrupted turning without sacrificing edge life. The MM5 chipbreaker promotes short, controlled chips when cutting stainless steel, helping to prevent entanglement and minimising downtime due to chip clearing. These features together reduce scrap rates and support a more economical machining process.

Application fit and handling guidance for workshop use

This indexable insert fits standard DNMG toolholders and is intended for general turning of stainless steels in medium to robust operating conditions. The 0.8 mm corner radius helps achieve a consistent surface finish while retaining a durable edge for longer tool life. For best results, pair the insert with stable clamping and appropriate coolant strategies to manage heat when machining heat-resistant stainless grades. The combination of design and grade makes the insert a reliable choice for batch production environments where repeatability and tool-change efficiency are priorities.

FAQ

What materials is this insert suitable for?
The DNMG150608-MM5 WMP20S from Walter Tools is specified for stainless steel (ISO group M) and supports machining under medium to robust cutting conditions.

How does the MM5 chipbreaker affect chip control?
The MM5 chipbreaker produces short, controlled chips when paired with the Tiger·tec Silver grade, improving chip evacuation and reducing the risk of built-up edge in stainless-steel turning.

Is the insert compatible with standard DNMG toolholders?
Yes, the insert uses the DNMG form factor and is compatible with conventional DNMG toolholders used for turning operations.

What advantage does the negative 0° rake offer?
A negative 0° rake provides a stronger cutting edge that resists chipping during interrupted cuts and heavier depths of cut, enhancing tool life in demanding operations.

Can this insert be used for finishing and roughing?
The insert’s geometry and 0.8 mm corner radius make it suitable for both finishing and robust turning applications; process parameters will define the final surface quality and productivity.
