DNMG150408 KS20 indexable turning insert, 55° rhombic, for turning — Tungaloy

The DNMG150408 KS20 is an ISO‑standard rhombic indexable turning insert designed for general external and internal turning, combining a balanced carbide grade with a double‑sided chipbreaker and a cylindrical centre hole for secure mounting.

• ISO DNMG shape, 55° rhombic
• KS20 Tungaloy carbide grade
• Double-sided chipbreaker, cylindrical hole
• 0.8 mm corner radius, 4.76 mm thickness

Consistent tool life and process stability from a balanced carbide grade

The specially developed KS20 cutting grade delivers a balance between wear resistance and edge toughness, which lengthens service intervals and reduces unexpected downtime. In practical terms, a stable grade reduces edge chipping and maintains dimensional accuracy over longer runs, supporting predictable cycle times. For manufacturers seeking repeatable results on mixed batches, the carbide substrate offers robustness under varying cutting loads while the grade’s composition supports economical performance in serial turning.

Geometry engineered for controlled chips and accurate profiles

The 55° rhombic geometry coupled with a 0.8 mm corner radius provides precise contouring and improved access in close tolerances. The double‑sided chipbreaker is designed to break and guide chips reliably, which reduces the risk of entanglement and protects the workpiece surface finish. The insert’s cylindrical hole and standard form ensure compatibility with ISO‑type toolholders; correct mating of holder form, clearance angle and tolerance class secures seating and repeatability in clamping systems, helping to avoid vibration and micro‑movements that degrade finish quality.

Workshop compatibility that keeps production flowing

These ISO‑standard inserts are straightforward to integrate into existing tool systems: the plate size of 15 mm, plate thickness 4.76 mm and the rhombic outline mean predictable mounting and straightforward inventory management. The insert suits both roughing and finishing when the matching chipbreaker and grade are chosen for the workpiece material. Clear labelling and manufacturer SKUs support traceability and reordering; for complex material mixes, selection of the correct chipbreaker and grade is the decisive factor for tool life and part quality.

FAQ

What materials is this insert suitable for?
The KS20 grade in the DNMG150408 insert is formulated for a broad range of turning tasks; the carbide substrate offers reliable performance on typical steels and mixed workpiece materials when the correct chipbreaker is selected.

How does the chipbreaker affect machining?
A double‑sided chipbreaker on this DNMG insert controls chip form and evacuation, improving surface finish and reducing the risk of chip interference during continuous turning operations.

Which holders are compatible with DNMG150408?
Compatibility is governed by ISO DNMG geometry, relief angle, tolerance class and the mounting method; the insert’s cylindrical hole and standard form fit ISO‑type external holders and boring bars designed for DNMG plates.

Can the insert be used for finishing as well as roughing?
Yes — by selecting the appropriate chipbreaker and cutting parameters, the insert can be employed for both roughing and finishing; the 0.8 mm corner radius supports precise profile work while maintaining strength.

What identification helps with reordering?
Use the manufacturer article number 6803411, SKU 6803411‑Tungaloy or manufacturer SKU TUN6803411 to ensure the correct Tungaloy DNMG150408 KS20 indexable insert is supplied.
