Rated 5 out of 5 by from Why did I wait so long!... My wife purchased an oscillating tool for me many years ago. I told her to return it since I have many types of saws to choose from. Well, long story short, I purchased this Rockwell Sonicrafter to trim the last few pieces of molding before tiling a bathroom floor. My backcut saw broke and I was in kind of a hurry. What a difference this saw made! The cuts were done in no time! I spent many hours manually backcutting trim for tile in my kitchen, hallways, and foyer. I could have saved a ton of time! I also used the saw to cut a PVC vent pipe in a confined area with no problem. I also was able to make a long needed larger cutout for my dryer vent that ran down through the floor. I cut a larger opening for a bathroom vent fan in drywall as well. I could go on and on about this amazing tool. Clean cuts, easy to use, easy to re-position or change the blade without tools, plenty of power at any speed. How did I do without this tool before! My Wife reminds me that I didn't have to if I only listened to her!

Rated 5 out of 5 by from Cut my time in more than half My husband and I are renovating an older home and there were nails everywhere - I was attempting to pull them out with a crow bar. Eureka! use the Sonic Crafter - cut them right off to floor level and done! Also used it to do some of the more difficult spots on cutting out smaller pieces of trim, drywall, you name it. Saved me tons of time as well as wear and tear on my knees. This was the first Rockwell tool we purchased and we love it!

Rated 5 out of 5 by from Ready to expand it's accesories!!! I bought this tool to cut an Avonite countertop as there was some close work at the back of the counter, the Sonicrafter handled the job with NO PROBLEMS, while my cut wasn't perfect, a few twists and a quick change to a sanding head and it's smooth as silk now. This tool will come in handy for MANY JOBS around your house or jobsite. I LOVE MINE!!!
