Question: is this variable speed? I don't see where the switch is located on the photo
Document: The on/off switch and the speed selector are located very well making for easy control. When you have this sander set on its most aggressive setting you can see the ridges disappear and you can feel the sander grabbing at the irregularities. You need to keep both hands on the sander when it is in this mode. I've got some 5&#34; RO sanders for sale - cheap. They are just shelf sitters now.
Don't waste $270 on this tool.I bought a flex L 3406 VRG lower rpm angle grinder with variable speed and use a flat sanding disk.This is for very rough work only.I love this tool works great.standard grinders won't work because they spin to fast and the disks burn up.
This is a well built and very able sander. I use it to strip bottom paint from my sailboat, and it has reduced my work time by more than half. With 60 grit paper, it is very aggressive. Best of all, its ergonomic design makes it easy and comfortable to use without fatigue. Sanding rate is easy to control with the variable speed control. Absolutely nothing negative to say about this great tool.
This sander is great. I replaced an old dewalt that was worn out, and the bosch is far better. With the shop vac hooked up it produces hardly any dust. The aggressive switch is fantastic when you need to take off a lot of stock. I did have to look hard for an adapter for the shop vac hose.
And for half the price I couldn't see why we should stay with the Festool as they really do require that you go all Festool or none at all. Not to mention some of the major annoyances I had with the rather expensive Festool -- at that price, the tool really should function perfectly and I shouldn't have to fight with it to change modes!If you are looking for a multipurpose heavy duty sander. . . don't overlook this Bosch!
It's smooth and has great dust collection when hooked up to my shop-vac. It is as aggressive as a belt sander but without the risk of gouging your work piece. And being able to flip the switch and go right into orbital sanding with the same grit cuts down tremendously on sanding time. I sanded 35 white oak doors and drawer fronts in about 2.5 hours and they looked awesome, normally I would have been there all day.
My title is somewhat in jest being that I own and have used many Festool products and they are great, but it seems to me that they have always been somewhat over priced and seem to be made out of more and more plastic every year. For months now, I have been contemplating buying a drum sander to help speed up production as well as tighten up quality in the shop.
I can lean on it all I want and it doesn't seem bothered at all! The grinder mode works great, I love having something in between a high speed, course grinder and the dual action sander, but to have it in one tool, phenomenal!Other Thoughts; This sander is not a palm sander, expect it to require mostly 2 handed operation. That said, it fits my hands great! I love it!
Having read an assortment of reviews about an assortment of DA sanders, I went with the Bosch 120DEVS. The project is sanding the hull of an 80' steel sailboat. This machine is unbelievable - it allows me to remove 2 thick layers of badly orange peeled paint with speed and precision on the stock removal setting. It is at least 1/3 faster than the 6" Rigid and Porter Cable machines that I was using.
I build cabinetry and fine furniture which started out as a hobby and turned into a profession. I have used a Ridgid variable ROS sander for most of my work which is a nice sander but liked the idea of the additional surface area gained by going from a 5&#34; to a 6&#34; disc as sanding is not my favorite task. I searched around like I normally do and while I own some Festool stuff I didn't want to pay the Festool price which led me to the Bosch.
