How Sharp are Carbide Insert SHIMS? Machinists, never used these so I need help! Answered
I have a few secret upcoming projects in which I plan on using carbide turning inserts. Both for woodworking and metalworking projects, but not machining - their intended use.
I was wondering if anyone has any experience using these. I was looking at buying square inserts, but I can find only shims like this: https://www.ebay.com/itm/292307002360 . Do you know if these are even slightly sharp? I mean, can I scrape wood with them with my hand, not in a milling cutter? Will they cut wood?
How sharp actually are these actual carbide inserts? Will these be able to scrape hardwood if I for example, hold them with pliers and scrap them across wood?
