Has anybody here had success at replacing the brushes in a Dewalt Mitre saw?

I’ve got about a 15 year old DW703 that has recently stopped starting. You can spin the blade (power off of course) a few times and then it might start. Or whack the motor casing a few times and it might start. Because it has been so dependable I’d hate to throw it away, but then i don’t think it would be worth mailing in for repairs.
Any suggestions for getting the parts or putting them in? It might be double insulated for whatever that means.

In any event I’m probably in the market for a new saw, a slider this time. Dewalt’s new DWS780 12” looks pretty attractive, and doesn’t need a ton of rear clearance. Anybody have experience with it?

Thanks.

I would go to Ereplacmentparts.com and order up the parts you need. It looks like a pretty straight forward replacement. You’ll have to remove a cover or two than free the old brushes before you can install the new ones. No reason to scrap a working tool over $20 in parts and an 1/2 hours work.
They have a forum on their website that possibly may provide more detailed information than I can supply from looking at an exploded diagram.

P.S. link is for DW703 type 1, there is also a type 3 listed, you’ll find this information on the tools ID plate.

I’m not a particular fan of Dewalt. The Bosch GCM12SD and Festools Kapex KS 120 are the top saws these days.

Ditto what PutnamEco said, I just ordered a set of brushes for my Dewalt 18V circular saw from them, cost me about $15 shipped. Couple of screws to pull the motor cover off and 15 minutes and you should be good to go.

The older ones are worth repairing as long as you can get the parts. I bought my DW compound miter saw just before B&D bought DW and my saw is bullet proof. I wouldn’t trade it for any of the new ones.

That might not be the brushes needing replaced, a partially shorted armature can act like that too.

You also may be able to find replacement brushes at ace hardware in the little bins of stuff, I found replacement brushes that fit a Dumor grinder there before. There are only a few different standard sizes of brushes.

Have your say...
