Personally, I use new projects as an excuse to buy new quality tools

Considering what contractors would charge for the same work, and that I probably do a better job, feeding my tool junkie appetite is cheap.

My Milwaukee 18v is just a terrific tool. Nothing stops or slows it in its never ending efforts to chew stuff up. And yes, these multi-tools are a godsend when shortening door casings or other trim for flooring. I personally also like cutting sheet rock for electrical boxes with it. That old plunge drywall saw can stay in my toolbox.

I picked up the 20 volt DeWalt last year for $100. I had a cheapie from Walmart to see if it would save me time. Needless to say, I upgraded as it works great and has a tooless hold down for the cutter. No more stripped bolt and loose blades.

When buying a multi-tool look for one that uses a good blade interface head. Some only use pressure to secure the blade, and they loosen up too fast.

Others have a mounting interface that secures the blades better, whether it's a bar or pin that keeps the blade from moving, or the new STARLOCK from Bosch and Fein that is probably the strongest out there right now.

My two- or three-year-old corded Ridgid JobMax multi-tool has changeable heads. I have the oscillating multi-tool head, a right-angle drill head, and a saber saw head for it.

The oscillating multi-tool head uses some kind of "star" fixture to clamp the cutters in place, secured with a hex-head machine screw. IIRC, it's designed in such a manner that it will accept cutters from several manufacturers.

I picked up the 20v Dewalt and let me tell you, it'll go through a piece of wood in 2 seconds that took the Bauer the entire 4 minutes of its life.
