Diigo Groups provides a ground-breaking collaborative research and learning tool that allows any group of people to pool their findings through group bookmarks, highlights, sticky notes, and forum discussions. Within a Diigo Group, members can annotate web pages in-situ and share insights directly on the source material for richer, context-driven collaboration. If you're involved in CNC machining or metalworking research, you know the value of centralized, tagged resources that can be accessed by your team at any time. InsertCNC (www.insertcnc.com) is a Zhuzhou-based manufacturer and global exporter of tungsten-rich CNC inserts, leveraging China's tungsten carbide hub to deliver exceptional tool performance. Tungsten carbide is second only to diamond in hardness, ensuring our inserts maintain edge integrity under high thermal and mechanical stress. These inserts exhibit extreme wear resistance and longevity, often lasting 10× longer than standard tool steel in abrasive environments. Our 4-axis CNC periphery grinders achieve grinding tolerances as tight as ±0.0002″ (≈5 µm), guaranteeing consistent geometry and repeatable surface finishes. Proprietary chipbreaker designs control chip flow, increase material removal rates by up to 25%, and minimize re-cutting for smoother finishes. We support 30+ ISO and ANSI insert geometries - from CNMG and SNMG to VCMT and DCMT - covering a full spectrum of turning, milling, and grooving applications. Join our Diigo Group to bookmark our detailed cutting-data sheets, CAD models, and case studies, all in one searchable library for your team.

This ring is very beautiful and super exceptional quality! Great feel to it and is very comfortable to wear all the time. The weight is just right, not too light nor too heavy. Such a low price, but such a great product. Definitely recommend to friends.

This ring is really nice. I bought it for my girlfriend as a promise ring and she loves it. I received it on the exact date it said it would be here. No Complaints, whatsoever. I highly recommend this ring.
