DNMG150616-MK5 WKK10S — Turning insert for cast iron by Walter Tools

The DNMG150616-MK5 WKK10S is a negative‑rake, 55° rhombic turning insert optimised for productive machining of cast iron in general turning applications

• Tiger·tec Silver coating for wear resistance
• Grade WKK10S optimised for cast iron machining
• 55° rhombic shape for versatile tool set-ups
• 1.6 mm corner radius for stable cutting forces
• MK5 chipbreaker for controlled chip formation

Reliable performance for abrasive cast‑iron work

The combination of the WKK10S grade and the Tiger·tec Silver coating addresses the typical abrasive wear associated with castings. The grade is tuned for short, brittle chips and frequent micro‑fracture, which means the insert maintains edge integrity under high abrasion. As a result, machining cycles are more predictable and tool change intervals are reduced, supporting higher throughput and lower unit costs in serial production.

Geometry engineered for stability and reproducibility

A 55° rhombic outline with a 1.6 mm corner radius and a 0° (negative) free angle provides a compromise between strength and versatility. The insert’s form gives robust support at the cutting edge, reduces vibration and helps maintain surface finish across varying depths of cut. With a clearly defined tolerance class M, dimensional consistency is ensured, simplifying fixture set‑up and repeatable results on CNC turning centres.

Coating and substrate explained for process clarity

This indexable insert uses a coated carbide substrate combined with the Tiger·tec Silver technology. The coating enhances resistance to abrasive wear and thermal loading while the substrate offers the toughness needed for interrupted cuts common in cast‑iron parts. For engineers less familiar with coatings: this means fewer premature edge failures and a more economical tool life when compared with uncoated grades in the same application.

Practical integration into production and tooling systems

Marked as DNMG150616-MK5, the insert fits standard DNMG holders and allows quick indexing to a fresh cutting edge. The MK5 chipbreaker promotes short, controllable chip forms, easing chip evacuation and reducing the risk of entanglement at the tool‑workpiece interface. Combined with consistent batch dimensions, the insert integrates smoothly into automated turning cycles and manual set‑ups alike, improving machine uptime and process reliability.

FAQ

Which materials is this insert intended for?
The WKK10S grade is specifically optimised for machining cast iron, addressing its abrasive nature and the tendency to form short, breaking chips.

What benefit does the MK5 chipbreaker provide?
The MK5 chipbreaker produces short, controlled chips that simplify evacuation and reduce the risk of chip entanglement, improving process stability during turning operations.

How does the Tiger·tec Silver coating improve performance?
The Tiger·tec Silver coating increases resistance to abrasive wear and thermal stress, which extends tool life and maintains cutting-edge integrity under demanding cast‑iron conditions.

What does the designation DNMG150616-MK5 indicate?
The code denotes the insert family and key dimensions: a DNMG (rhombic 55°) geometry, plate size 15, thickness code 06, corner radius 1.6, and the MK5 chipbreaker configuration.

Is the insert suitable for standard indexable holders?
Yes, the DNMG form factor conforms to common indexable insert holders for turning, enabling straightforward integration into existing tool‑holder systems.
