We are pleased to now offer Roto-Clip labeled inserts. These inserts are compatible with all of our existing flat discs and will stand up to any test you put them through. Comes as a set of 10 interchangeable flat inserts. Each insert has two sharpened edges that can be used to trim an average of 50-75 cows per edge. Every insert can be sharpened 3-4 times before they will need to be replaced.
