I used it for Chain replacement work of 530 Size.
Because it was a good atmosphere, I bought it and used it was not satisfactory.
Only Cut can be done easily, but press fitting and Crimp are useless.
Although press-fitting is impossible, the part holding down Plate turns round, the two holes are empty Plate is made with the position of Pin and Large crimp of Limit, so it is difficult to do thoroughly.
Body turns when Crimp work is done to Crimp width specified by Manufacturer. So you will not be able to do the next work.
I think that this item will be disposable so it is better to buy other items or exchange the Chain by paying the fee at the shop
