Wrapping up the 3rd season with a DeWalt 996B turning a 7.5" K-Drill through at least 500 holes/season. It just let me down for the first time, but I attribute that to not paying attention to heat build up while drilling multiple holes through close to 3ft of ice.
A plastic centering plate nests with the plastic fan piece fixed to the stator shaft, and these got hot enough to melt and weld themselves together when the drill stopped turning. I was able to break the weld without breaking anything else and get it running again. I was pleasantly surprised to see how good the internals looked after all the use it's seen. Motor and gears all looked like new. Not abused but definitely run hard.
I was curious how long the drill would last so thought I would share for one data point. I will keep using this one but also picked up a 999 for a backup.
Keeping batteries comfortable on the ice is key to getting all the available power. Keep the batteries in a cooler and add a hand warmer to keep them from getting cold. Keep the battery in an inside coat pocket or the cooler when not using. Switch batteries if drilling many holes in a row to avoid overheating the batteries.
Remove the K-Drill and hit the drill chuck with some WD-40 and spin all the way in and out once or twice a season to keep the chuck from binding.
