After trying this abrasive MOUNTED point, I am beyond impressed with how effective and efficient it is. The deburring edge rounding stainless material is easy to work with, and the triangular shape makes it easy to reach tight corners. As someone who works in the industrial and scientific field, this tool has been a game-changer for my work flow. The grit is perfect for smoothing rough edges, and it lasts a long time too .My only con would be that it's a bit pricey, but it's worth every penny. overall, I highly recommend this product..
