Dewalt 235G clogged up


Hi;
I have a 5yr old DeWalt DW235G 1/2" drill. On several occasions, I used the drill in the attic to drill holes through floor joists for wiring. There is Rockwool insulation in this area, and although I cleared as much as I could from the area I was working, some of it got into the drill. The drill continued to work fine, but after more use I noticed that the air vents were partially blocked.

Today, I took the drill apart, and thoroughly cleaned out the case. I went so far as to remove the entire motor assembly from the plastic case. There was Rockwool just about everywhere.

So now I've got the drill all back together and it's working great. But I have to ask myself: what can I do (besides the obvious) to prevent the drill from getting clogged up with whatever material is in the vicinity of where I am drilling? It would be great if there were a filter that could be placed over the air intake vents in the case, so all I would need to do is clean the filter after each use. But I have never seen such a filter.

What do the pro's do about situations like this? Sure - the pro's probably don't use this particular model drill, but don't all hand drills have vents in the case?

In the future when I work in areas where material can get sucked into the drill, I will do my best to remove whatever material there is, and lay a sheet of plastic over / under it so that it doesn't get into the drill.

Here's a photo of the drill, showing the air intake holes. If I could get some sort of foam filter to fit over this area, I think it would do the trick - but how to do this without interfering with the operation of the drill...





Any ideas?

Thanks

FW

Tape some dust mask materials over the intakes. Just a thought.

taping over the vent holes will cause it to overheat quicker by not getting airflow through it

a better idea is to keep a blow tool handy and simply blast it with air after times when drilling in dusty environments. i do this with all my trim tools at the end of every day this includes saws, routers, nailers and sanders

I think what BigJim means is to tape the dust mask material over the holes, but place the tape so that it does not cover the holes. I think this would work. Dust mask material is much thinner than foam, and is better for filtering that kind of stuff. After all, I can breathe through it. I'll give it a try.
This reminds me that I need to get some more dust masks.

Thanks

Thanks guys;
I think you've given me a number of options here. I'll see what works the best for my next project.

Stretch an old sock or panty hose over the whole drill. Cut off the toe.

If those fibers are floating around I hope your wearing respiratory protection in any case.

Another idea that I've used is very cheap, (and works fairly well, though not great), is an old square house fan with a typical air conditioner filter just taped to the back of it. Just put the fan near your work area and ideally - besides keeping the area cooler if it's hot - any fibers floating up would get sucked into that stronger overall flow and the filter rather than your tools.

if your only doing 1-2 holes at a time. taping over the holes will not hurt anything (unless they are pita holes).

or. a paper bag. put some tape on the bottom of it. put the drill inside the bag, poking a hole with the drill bit. the bag then becomes an umbrella.
