As a hesitant buyer, I purchased this Milling Accessory for my PROJECT. As a result of using this product, I found that it did not live up to the standards that i was expecting. The compression and uncoated features are not enough to justify the hefty price tag.Industrial and Scientific tagging seemed more like a marketing gimmick rather than a reflective feature. While it did work for a short while, it didn't maintain its durability long enough for me to be satisfied with my purchase..
