I was recommended to buy an SCLCR tool holder until I get more comfortable grinding HSS , I followed the advice and got one with a couple of carbide inserts (plus a couple of HSS inserts) anyhow the carbide inserts broke when the workpiece(store bought M8 bolts) got a little too loose in the chuck.
Now I'm looking on ebay to buy a package of these CCMT 21-51 inserts, there are so many choices that's mind boggling, then I see some carbide inserts are advertized as "Ceramic", what's the advantage of getting ceramic? sounds gimmicky to me unless there's something that makes them better that I am not aware of.
What do you think of these Ceramic inserts?
