Don't know about splitting motors apart though. I think you would need something like a chisel bit that was a foot wide. The point of it would have to be pretty sharp to wedge between the laminates and split the motor. It doesn't seem like the tool would have the power to do that. I think you would need something like a 40 ton hydraulic press to split a motor apart.



I usually cut one end off the windings with an angle grinder and then use a punch to drive out the copper. It's the best way i've found to do the job.

I saw a video on it not sure if it's a hammer drill or not it says it is though is it or is it something else ? They sell it for 200$ for the machine and 5 bits and 150$ for shipping and 5 percent fees the bit they use is 5in wide almost. I paid 199 for a Milwaukee corded and free angle grinder plus 30$ for a chisel bit that's for concrete cant find any chisel bits made for chopping through metal haha.

I did 18 motors in 2hrs with the ads hammer drill works pretty well hardly any dust still have a long way to go haha. I'm going to get a wider bit though I still have the string to take off though that part sucks.

I looked into the SDS bits Mike. The widest one i was able to find was 6" wide. They aren't common but they are out there.

Try google search term 6" wide SDS chisel bit. It will turn up a few results.

Amazon has them I think. Going to do more today
