Ridgid Jobmax corded and I would buy it again.
I have the Ridgid Jobmax
corded $100 without coupon. So that meets your price.
I've used lots of blade brands, mine is older so it's an allen wrench change which I think the newer ones have quick change, but the other "heads" are twist off... sander... recip... metal shear... drill driver. It however does
NOT meet your requirement for "low to reasonable noise/vib". It's very loud MAYBE the current model is better?. I've cut wood with it and some metal. Lifetime warranty, but whenever I've send a Ridgid tool in for warranty repair they take it and I'm without that tool usually for 3 months. So it's come back fixed, for free, but in some cases I ran out and purchased another tool to finish my project while it's getting "fixed". If you go with battery op the one that comes with the tool does NOT have lifetime warranty but if you buy batteries separate they do which is probably the best battery value, but I wouldn't recommend this tool in battery.
I need to cut some sections of door and window frames that have rotted. I’m definitely not a carpenter or even very handy. I’m looking for a good oscillating tool under $150. “Good” includes accepts universal blades, easy to change accessories, low to reasonable noise/vibration, adequate power for cutting wood and well-made. Corded. Good warranty is a plus.
If I went only by reading Amazon reviews I’d never buy anything.
Suggestions please. Thanks very much.
