Would guess it might take 30 days to get it back. Your not looking for warranty work ? Just to get it repaired ?
This would be to have Milwaukee fix it.
I just did my 10 or 11 year old 1/2" impact in April. It only took two weeks from the day I sent it in to when it arrived back. For 125 bucks I had a 95% new impact. 11 bucks to ship it back to me. They payed to get it to them. A new one like mine, the cheapest I could find was $179 in a couple different places. If it would have been completely shot, Milwaukee would have sent a new one. Pretty satisfied with the service.
