### ⭐⭐⭐⭐⭐ They do last longer!
*by A***R on February 26, 2024*

90% of what I do with my CNC Machine is surfacing table tops. I was literally in the middle of surfacing a solid hickory top when I switched to these new coated carbides. The non coated would start burning after about 2 1/16" passes. These coated ones didn't start burning until the 5th pass. These are great, at least for what I do.
