About Bosch Random Orbit Sanders In Bosch's random orbit sander family, you'll find an assortment of powerful, versatile sanders and polishers that are designed for low vibration and minimal noise. These models feature counterbalance mechanisms that serve as the basis for the dual bearing pad mount system, which can be operated with one finger on a soft grip.
About the Bosch 1250DEVS Random Orbit Sander
The 1250DEVS multiple-purpose sander from Bosch has two sanding modes: random orbit mode for normal stock removal or fine finishing, and an aggressive "Turbo" drive eccentric orbit mode that operates at five times the regular rate, in order to remove rougher stock. Its simple sanding mode selector switch quickly changes back and forth between the two modes, as your projects require it -- and the powerful 6.5 amp variable speed motor (3,100 to 6,650 opm) matches the tool's speed to the task, for a smooth result on all surfaces.
This model is crammed with great convenience and power features, including a soft start function that tones down the start-up torque and a variable speed dial that makes it extra easy to match your working speed to the project. It also has Constant Response circuitry that maintains the pad speed under heavy loads while simultaneously protecting against overloads, and an integral pad dampening system to help prevent swirl marks -- plus a passive dust collection system (vacuum and hoses required, available by Bosch). The 1250DEVS uses 6-hole, 6-inch hook-and-loop discs. This kit includes a dust tube, soft backing pad, a left or right-hand auxiliary handle, one sanding disc, and a pad wrench (5mm) that stores on-board.
Applications
The 1250DEVS removes stock and finishing material quickly, without scratching -- making it perfect for most sanding jobs, from wood floors to furniture finishing. Bosch makes an assortment of 6-inch hook-and-loop discs and pads to fit this model, including discs for wood, paint, and special applications.

Customer Review: Festool Who?
I needed a sander for resurfacing my deck and while a belt sander would have been ideal it was not a tool that would get much use outside of that task. This sander worked so well that I do not feel I "sacrificed" anything. The "Turbo" mode removed material so fast it was amazing. no vibration what so ever. Once I was done with that job I wanted to test it on so furniture and it worked perfect. my 5" RAS will now sit on the shelf. You cannot go worng with this sander for any and all your sanding needs.
Customer Review: mixed feelings
I have to disagree with the glowing reviews of the sander. My previous sander was a Dewalt and I decided to replace it as I was getting a large number of swirl marks from it with the very hard woods that I like to work with (Wenge, Bloodwood, Purpleheart and so on). I bought this sander on the strengths of the reviews as a replacement, and overall it has not performed as well as the Dewalt. Part of that seems to be design and part that it is just not the right tool for the application. Strengths: 1. This is a very powerful sander. The motor does not break a sweat on anything. 2. The "fast removal" mode lives up to its name... it's very rapid. 3. Seems to work adequately as a polisher, though attempts to use it like this have always resulted in swirls in the finish. That could be user error though. Weaknesses: 1. Intense vibration. You need to have some good vibration absorbing gloves on when using this sander, and long term this kind of vibration is no good for your hands. I worked on the assembly line doing spot welding and I know long term what vibration does to your hands. It's terrible. 2. The same strong motor that doesn't flinch at anything can cause the sander to dance over the surface if the sandpaper grabs instead of gliding. The "fast removal" mode can throw the sander out of balance so that it wobbles and jumps all over the place. Small workpieces need to be clamped in place or else the sander can spin them on the bench. Surfaces that are not perfectly flat cause imbalanced friction on the disk and that can cause some of the jumping around. You need two hands on this, and a firm but light touch at all times. This is in contrast with a smaller, lighter sander that will glide. 3. Regular sanding mode doesn't feel like, in spite of the power of the sander, to remove material any quicker than a smaller, less powerful unit. In combination with the two handed use and the constant threat of the sander jumping, it seems to be a net negative as a tool. 4. "Swirl Free Finish" once again does not live up to its promise. Everyone promises this but few deliver. I think this is really highly dependent on the kind of material you're working with. So overall for myself, I think a lighter less powerful unit would have been the better choice.

Gets the job done in half the time. Covers 78% more surface area than a standard six-inch sander. End up with a smoother, better finish. This variable speed sander has an instantaneous electronic feedback system. This advanced electronic circuitry maintains constant RPM. No matter how much pressure you apply, you won't stall this tool. When you use the Fein sander with a Fein dust extractor, you capture 98% of the airborne dust created from sanding. Dust-free sanding provides a better finish. The sandpaper stays cooler and won't load with particulate or broken abrasive. And, sandpaper life is increased as much as 10 times.
