So far this product has been amazing. It was purchased to mill the trigger area into a block of aluminum. Works much better than a chisel to be used with a jig at a fraction of the cost.
Pros
Aluminum Titanium Nitride (AlTiN) coating lubricates the end mill for high temperature stability and abrasion resistance at high cutting speeds and offers better heat resistance than TiN, TiAlN and TiCN coatings
