Works as expected/nice to have a combo pack

The grinding attachment fit easily into my drill (yes, you need your own drill to make this work) and I was able to sharpen my old mower blade on both sides to help improve cutting performance. I did remove the blade from the mower (I've seen some reviews of these drill bit grinders suggesting you can leave the blade on the machine) as I suspect it helped properly access the blade. Plus, this is the only way you can use the balancing tool. Removing the blade was easy with a socket wrench, so no need to be intimidated by the process. My blade will likely need to be replaced at some point due to old nicks and notches, but this tool has helped extend its life. I will be sure to use this at least once a year to make mowing easier.

Good Little Kit

[This review was collected as part of a promotion.] The drill attachment is unique in that the blade is sharpened by inserting the blade between the two-part sharpening stones, not by just grinding the blade with a drill-powered stone.
