I recently got my hands on the "Golden Coated Tungsten Steel Milling Inserts" and I must say I was impressed. These 10 inserts can withstand a lot of heat and pressure, and cut through steel and stainless steel like butter. I found that they produced much finer finishes than some other inserts I'd used before. One thing to note: these inserts are definitely on the pricier side, but I think they're worth it if you're looking for quality and precision. Just make sure to use them properly and not to put too much force on them. Overall, I'd give these inserts 4 stars out of 5.
