    New Dremmels

    Ever run into those Lennox coil leaks on the condenser unit??? The dremmel is the best tool to use to take care of this issue. Cut out some fins and then cut to copper line, insert a piece of 3/8 copper and bam problem solved.... Saves the customer alot of bucks.

    New dremmel tool? Or the same old ones? Dremmel has many products out now, are you referring to a new tool in particular? Needle nose pull them fins out quite well.

    Multi-Max 2.3-Amp Oscillating Tool Kit the Rotary one sucks. It throws crap into your face this one cuts like butter and you dont have to worry about the spinning of the blade it just vibrates and cuts it is the bomb. Go to Youtube and search for Lennox leaks and you will see it, however, back then I used the Rotary one. The next time I do one I will post it.

    I started using an oscillating saw for a similar job.

    The issue that I see with it is, the oscillating action can cause the tube sheet to move on the tubes, potentially causing another leak or, at least make a weak spot weaker.

    It sure does cut nice, though, doesn't it??

    I didn't see a use for one until I bought a cheap one on sale for $40. Now I seldom find a situation that I can't use it!
    First time I used it on a job, was for a re and re ice machine. Old one plumbed in with pex hidden behind counter. I had six inches working room and fought for 10 minutes with sidecutters until I remembered I had it so I used the narrow saw blade to burn through the pex clamp ring in 20 seconds.
    Felt stupid and great at the same time!
    I keep it in my scraper tool bag as I often use it to scrape baked on gaskets from heads and valve plate surfaces. Careful if you try this as if not done right you can cut into the metal surfaces.

    I have also used it to cut rectanglular holes straight into drywall and wood for receptacles and the like. With all the blade options available, it has become my most versatile cutting, grinding, and sanding tools.

    My next purchase will be the Fein brand version as I'm told that it's the best one made.

    I have a generic oscillating tool and it has its place. I am using it more and more. It is nice for installing old work wall boxes and other light duty jobs. I have used it to notch trim and cut out a sink hole in 3/4 plywood! Tough tool.

    I'm and installer, looking for an easier way to trim back sheet metal plenums during changeouts. I've considered an oscillating multi tool for the job. Anybody ever used one for this application?

    Not the tool you want for that application.
    Check out the milwaukee twin cut power shear or the dewalt 20V cordless power shear with a rotating head. Can't seem to post pics right now...
    Oscillating tool is good for softer materials, not so good for sheet metal.
    Spend the money reap the benefits.
    You could also find a princess auto (Canada) or harbor freight (US) knockoff for under $100 that would still last a coupla years.

    As koolkahuna said, use a uni-bit to start then have at it with the "double cuts" (my name for same tool). I also keep a corded die-grinder with a cut-off wheel in it to cut thru the seams for a cleaner finish cut.

    On the pipe and duct..... I would just use red and greens side by side.... a little more "waste".... but its faster than double cuts.....
