Question: Is this a one-half sheet sander? If so, how does it compare with the Porter-Cable one?
Document: Bought this due to the price and brand name. Very impressed by the low vibration and quick sanding. I've bought 3 of them. One for each grit of sandpaper I use. Only thing I didn't like was the paper changing mechanism. I like the clamp type that Porter Cable has. I would recommend this product and buying from Amazon
I typically buy quality tools porter cable, dewalt, craftsman professional series, this Makita sander is Great durable pad, fast sanding, low vibration and excellent dust collection, only complaint is the port is too small for a normal vac hose to fit if you need something more then the small reusable bag. Excellent sander for the money!!! !
Needed something bigger than a mouse sander and considered the half-sheet model but this is an excellent compromise.Really like the fact that you can use standard paper and it is very easy to swap sheets. The sander is light enough to do vertical surfaces. I found the bag to do a pretty good job. It is necessary to empty it every 30 minutes or so. Could not find this model in stores, Only on-Line
Understand, I am a guy who has gone through 4 Black and Decker sanders in the last 4 years. I think it was more of just being a meiser & not being willing to pay a liitle more for a better product. This one quietly purrs like a kitten & gets the same job done in less than half the time of those B&D POS's I used to own.
I like the fact that it can use a regular sheet of sand paper. Just cut a full sheet of sand paper into thirds and it easily and securely attaches to the sander. It has a large work surface which helps keep the work smooth and uniform. This sander is perfect for a large flat area like a table top.Update: I finally got the opportunity to compare this sander to a 1/4 sheet sander by Craftsman. This sander is much, much better than the Craftsman sander.
The on-off switch of my cheap Black and Decker 1/3 sheet sander died. I wanted to replace the B&D; with a higher quality sander. It appears Makita is the only manufacture offing a quality 1/3 sheet sander. I purchase this sander from Amazon after on-line searching and shopping. The product arrived less than one week.At first glance, the sander is obvious of better quality than the B&D.
Since I was so pleased with my little 1/4 sheet Makita I was hoping there would be a full size Makita in my price range. There was and I'm so pleased with my purchase! Besides being a very comfortable sander to operate, I love the ease of changing the paper! No more trying to squeeze a super stiff spring with one hand while trying to insert the end of the sheet! That's always been such a difficult task for me. Makita's design is such a great improvement!
I use this sander along with a random orbit sander. I find that this one is best on small to medium pieces where I don't want the edges rounded at all. This really is the right size for my use. It is larger than a palm sander and smaller than a 1/2 sheet, which seems to be more flexible in my projects. I also like being able to use my own sheets and the included punch for dust control. Also, sheets are cheaper than random orbit sander.
I purchased this item after my VERY old B/D sander finally died. What a difference. This sander though heavier has much better vibration control, and the noise level is not even comparable. I was really impressed with the dust collection vacuum on the sander. it works great as a stand alone collector but when paired with an auxilliary collector there is virtually no dust. 1/3 sheet sanders are getting hard to find, so I am glad I bought this one.
So goodbye forever to the palm sander world. Also worthy of praise with this tool: low vibration, comfortable handles, and effective dust extraction: quite good with the bag, excellent with a triggered vacuum. I also like the way that Makita has improved the paper locking mechanism, which was never a strong point with its older models. Efficiency tip: insert three sheets of paper at a time in the machine. When a sheet wears out, simply tear it away and keep on working with the next one.
Answer: yes
