Review on Cobra Carbide 40935 Turning Multilayer by Paulo Hoelzle

Based on my experience, this indexable insert works top notch. It makes a clean, smooth cut on my lathe and has a long lifespan. The multi-layer coating helps decrease wear and tear, making it a cost-effective choice for industrial and scientific applications. The only downside is that it's a little pricier than other inserts, but you definitely get what you pay for in terms of quality.
