These inserts are a fantastic choice for industrial and scientific cutting applications. After I put them to the test, I was impressed with their durability and consistent performance. They are also very easy to install, saving me time and effort. The only downside is that they are slightly more expensive than other options on the market, but the quality justifies the price.

Pros
Long-lasting due to the multilayer coating
Cons
May not fit all types of machinery due to its specific size and dimensions
I have used various OCARBIDE inserts and have no complaints. I only machine aluminum so I can't vouch for using other materials but for a hobby machinist they seem good value for money.
I use these bits a lot, especially when turning hot rolled steel. They offer surprisingly good coverage compared to other carbide inserts, but (certainly) not as smooth as you can get with a sharp HSS rotary bit, but close.
