I have dropped my T15 many times I have had it for years!
I dropped mine 5ft onto concrete and broke e-tech dail on back of the drill. Still worked fine.
Then my mum borrowed it and drop it hip height onto concrete and broke the e-tech dail even more. Kinda annoying but it still works.
It was a Friday and I was working on a job and left my drill outside. I forgot about the drill and went home. I went back to the job on Monday seen my drill outside and was absolutely gutted!
I was gutted because it had been raining really hard all weekend! Typical when I left my drill outside.
It was soaking and as I lifted it up water came out everywhere from the battery and motor.
I took the battery off and left it to dry for a day. This was a year ago and the drill is still working now.
