I like these cutters because they are inexpensive but perfectly matched.
The bits in this section are important to me Turning on hot rolled steel is especially challenging. Although, they produce a surprisingly good finish when compared to other carbide inserts, they (of course) do not produce a finish as smooth as a sharp HSS turning bit. Close, but not quite.
The product is good.
I couldn't be happier.
It has been my experience to have used several different types of OSCARBIDE inserts without issue. The only material I machine is aluminum, so I cannot attest to the quality of these products on other materials, but as a hobbyist machinist these are inexpensive and seem to be a good quality.
The last couple of months have been good.
I love the way they cut!.
