Babetta engine piston grinder tool

Useful tool for those whose piston doesn't exactly fit their cylinder and needs to be sanded a bit. Hole for the piston peg is 14 mm. The diameter of the tool is 12 mm so it should be able to fit into your drill that you will use to hand-sand the piston down. Also great for polishing the top of the piston! Boost Mehighly appreciated
