After trying this diamond dresser, I was shocked with how efficient it was in grinding and shaping metals .The tapered structure provided precision and accuracy, making it easy to use. A great pro is that it`s compatible with most grinding wheels, which is a major plus. The only con I can think of is that it may be a bit pricey for those with a tight budget. Overall I highly recommend this product to anyone in need of a reliable diamond dresser in the Industrial and Scientific field..
