MP-08-0058 - This tool is versatile enough to be used on cam chains or drive chains, from #35 all the way up to #620! For 520 chains and up we recommend that you grind the head off the rivit first. Each kit includes 3 pin sizes to fit most chains [2mm, 3mm & 4mm] and is investment cast, hardened body etc. Also included are press plates. This kit will both break a chain, press the side plates together then rivit the pin. Perfect. Another quality tool by MOTION PRO. Plese note: This tool willl rivet hollow pin type master links such as DID - it will not rivet solid pin type master links such as Regina.
