Metal turning insert DS2000

for aluminum alloys

Overview
New DLC coating grade designed for turning and threading of non‑ferrous alloys. Combines high coating hardness and heat resistance with superior adhesion to minimize built‑up edge and produce high‑quality glossy surfaces.

Applications

• External turning
• Internal turning
• External threading
• Internal threading

Features
DLC coated inserts

• Tungaloy original DLC coating grade optimized for aluminum alloys and other non‑ferrous materials
• High resistance to built‑up edge for improved surface finish
• High coating hardness and heat resistance to reduce abrasive and thermal wear
• Advanced coating adhesion technology ensures stable, repeatable machining

Performance Highlights

• Exceptional resistance to built‑up edge and excellent surface quality
• Superior wear resistance from a hard, heat‑resistant DLC layer
• Consistent machining stability due to strong coating adhesion

Grades

• DS2005 — Excellent wear resistance; long, stable life in high‑speed machining of non‑ferrous metals
• DS2015 — Balanced wear and chipping resistance for a wide range of turning/threading applications
• DS2025 — High fracture resistance for stable finishes in interrupted cuts of non‑ferrous materials
