this year on dvl dirt and sand blew on the ice in some places and it sucks on auger blades. 2 sets of strikemaster blades on my 24 volt, put my kdrill bit on and have gone through 3 sets of those, did you guys know there are 7.5 inch, 8 inch and 8.5 inch kdrill blades. I think i may have cooked my 24 v strikemaster as it is amping out and stopping almost constantly.
