optimistspencer Posted August 17, 2015 Report Share Posted August 17, 2015 I saved a homeowner drill that I'm estimating to be late twenties from the garbage yesterday and I want to clean it up. However, in order to open it I need to take off the collet, which is rusted shut. What is the best way to open the collet screws? I'd rather not use anything very harsh, simply because I want to degrade the metal as little as possible.

jbw55 Posted August 17, 2015 Report Share Posted August 17, 2015 Penetrating oil but if your worried about damage to the metal here is a recipe that someone turned me onto and it works.....50/50 mix of acetone and dextron/mercron automatic trany fluid in a spray bottle and shake before spraying, let it soak for about 10 minutes.

RickyMcGrath Posted August 18, 2015 Report Share Posted August 18, 2015 Look up Kano Kroil. Has amazing reviews on just about every site that sells it. Quote Link to comment Share on other sites More sharing options...

Atlas2000 Posted August 19, 2015 Report Share Posted August 19, 2015 Don't know much about products nowadays, but back in the day we would soak things in Marvel Mystery Oil. They actually still make it! Quote Link to comment Share on other sites More sharing options...
EEtwidget Posted November 5, 2015 Report Share Posted November 5, 2015 Like they said, try penetrating fluid that has a rust dissolver.hit the screw head with a hammer to help break the rust. Use a screw extractor kit or fluid (even a rubber band). Heat works too, just don't burn anything that's flammable Quote Link to comment Share on other sites More sharing options...
hemdale Posted November 5, 2015 Report Share Posted November 5, 2015 My best tool for rusted screws is this one below: http://www.engineer.jp/en/products/pz58e.html I was a bit reluctant at first but then I've tried it at home and on rusted screws under a washing mashine it yup, it works like a charm. VERY impressed. A bigger size would be this one: http://www.engineer.jp/en/products/pz59e.html You also have the Loctite Freeze and Release but I've never tried it so can't comment. http://www.henkelna.com/industrial/product-search-1554.htm?nodeid=8797940809729 Quote Link to comment Share on other sites More sharing options...

NERemodeling Posted November 5, 2015 Report Share Posted November 5, 2015 If your talking about the bolt inside the chuck that holds it to the drill then I'm 99% sure that is reverse thread. Clockwise to loosen it. They can be pretty stubborn even without rust Quote Link to comment Share on other sites More sharing options...

Let's see some pics of this thing Quote Link to comment Share on other sites More sharing options...
