Wow they said it was a hammer drill on the description it is electric though I could have bought one from the china recycle company for 350 plus 5 percent fees and 5 bits. But I decided on a SDS hammer drill cause I thought that's what it was. Guess if it don't work like that I can always use the grinder I got for free when I got the hammer or I can use the chisel since sawzall makes copper go everywhere. Thanks for clearing that up they lied on the video description then.

After watching a 2nd time you're right it is an electric hammer.

Oh I was worried for a minute haha. I'm going to try mine today after work.

I just use the grinder with a 1/16" cutting wheel. It gives a nice clean cut if you do it right. Trim the copper end off flush with the steel laminate. Use a punch to drive out the rest of the windings.

Did a couple of electric motors yesterday. They only took four or five minutes each. No mess to speak off. Not hard to do once you work out a method.

True I should have 900$ with current prices at 3.30 for num 2. 37 compressors 2lb copper each and 84 or so of motors 2lb copper each then small motors not sure on those have to break down one of each the window ac motors but has two small motors in it instead of the one big one. Some of the motors has metal tabs folded over you can pry up with plyers and the other small ones have the rivets that I have to pound in-between to break the aluminum rivets maybe I'll try the er drill on those haha. Plus hopefully brass to sometimes they are steel sadly you don't know till you pop the compressor open.

Also angle grinder didn't come with a disk should I get a metal disk? My angle grinder is a 4in I think it said.

I think that works out to 275 lbs of #2 copper from everything. It's hard to say. Electric motors are a source of scrap copper but it's quite a bit of work for what you get out of them. Prolly best not to count your chickens before they hatched. Just enjoy the work ... make a consistent effort ... and it will add up over time.

The fun part for me is to work out the best way of doing the job. The right tools can make all the difference in the world. That video where the guy was splitting the stators in half with an electric hammer was pretty cool.He can bang em' out like nobody's business. Makes it look easy.

It's a judgement call i guess. A good tool like that would be expensive to buy. That would be the tool to have if you were processing electric motors all day / every day. The tool would pay for itself.

I suspect it might be intended to be used as an electric jackhammer. That's a different critter from a hammer drill. Try using the search term " Scrapping with an electric jackhammer " on youtube. It will turn up a couple of results. I think one of them was the video you posted Mike.

It seems like it works but maybe isn't quite as easy as it's made out to be. Look at all the different cutting bit changes in this video. ( Still quite a bit like work ! )

Yeah ... you might try a 1/16" x 4" metal cutting disk and see how it works out for you.

I bought a Dewalt 4 1/2" angle grinder years ago for about $ 100.00 and have been pretty happy with it. It's something i use on a regular basis when i'm scrapping. That ... and the sawzall are my "Go To" tools for most scrapping jobs. They make life a lot easier.

Anyhow ... yeah ... try it out.

If it turns out that you like the cutting discs .... you can buy them in a bulk pack of 25 or 50 on Amazon. It's a lot cheaper than buying them individually at the hardware store.
