yes works a treet out on site and can get around 5 full set sharpens to a charge on the grinder. I did use the inserter teeth for a while on a 252 for a while and found them very hard to sharpen so didnot like them but when new they were good....
Would never put finger stile teeth in a grinder ever again after having one fly out while working and tap on a front door at the opposite side of the street.
Hodge do you finde the handbrake sticks on so you have to bend down and get a face full of exaust gas every time you want to role forward?
