Product Description

Color: NA

Backed by a powerful 3.3-amp motor, the Bosch 3727DEVS Random-Orbit Variable-Speed Sander/Polisher makes quick work of sanding, stripping, and polishing jobs. Thanks to Bosch's enhanced random-orbit sanding action, you can count on the 3727DEVS to deliver a clean, swirl-free finish every time. This multipurpose sander uses standard, six-inch hook and loop disks that are easy to change, and it includes a dust canister to protect your lungs and keep your workshop clean.

The Bosch 3727DEVS Random
Orbit Variable Speed Sander/Polisher includes:
  • Microfilter dust canister (RS026)
  • Soft backing pad (RS6045)
  • Removable front handle
  • 5-millimeter hex pad wrench
  • Sanding disk

A microfilter dust canister keeps potentially harmful particles out of the air. View larger.

Bosch's enhanced random-orbit sanding action and trademarked Constant Response Circuitry safeguard your work surface. View larger.
Enhanced Random-Orbit Sanding Action for a Clean Finish
Whether you're stripping old furniture or prepping new molding for installation, the 3727DEVS delivers aggressive stock removal and a clean, swirl-free finish. Free rotation and a 5/32-inch eccentric orbit diameter (5/64-inch offset) allow the sander's pad to duplicate a natural, hand-sanding action and ensuring that abrasive material never follows the same path twice. This enhanced random-orbit action combines with Bosch's unique integral pad dampening system to keep your workpieces free of swirl marks.

Versatile, Powerful 3.3-Amp Motor for Fast, Smooth Results
The 3727DEVS's 3.3-amp motor provides the power you need to remove stock quickly and efficiently, making fast work of difficult jobs. Bosch's trademarked Constant Response Circuitry maintains constant motor speed no matter how tough the job, providing overload protection and delivering a reduced-torque soft start that safeguards your work surface.

A variable-speed dial lets you adjust from 4,500 to 12,000 OPM for job-specific performance. The 3727DEVS's microcellular backing pad contours for a smooth, fine finish on all types of surfaces.

Since the 3727DEVS uses industry-standard six-hole, six-inch hook and loop disks, you never have to waste time searching for expensive, proprietary abrasive disks, and you never have to deal with messy adhesives.

Ergonomic, Long-Life Design for Extended Use
With a tapered, soft-grip top and ergonomic front and rear handles, the 3727DEVS offers multiple grip positions to help prevent user fatigue. The front handle can be removed easily for sanding in tight spots, and the conveniently placed trigger features a lock-on button for comfort and control during extended periods of use.

The 3727DEVS also features rugged, die-cast aluminum gear housing and an exclusive dual-bearing pad mount that eliminates wobble and vibration, extending the life of your tool and improving your comfort.

Dust Canister for Safety and Convenience
The included Bosch microfilter dust canister with integrated paper filter provides an optimal system for filtering fine dust. The canister traps particles as small as a 1/2 micron in diameter, and it reduces your exposure to potentially harmful particles by collecting more dust than other leading brands.

The compact Bosch 3727DEVS weighs just 5.2 pounds. It is backed by a one-year warranty, 30-day money-back guarantee, and one-year service protection plan.

What's in the Box
Bosch 3727DEVS Random-Orbit Variable-Speed Sander/Polisher, microfilter dust canister (RS026), soft backing pad (RS6045), removable front handle, 5-millimeter hex pad wrench, and sanding disk.

I have owned my 3727DEVS 6" sander for three years and have used it for both fine woodworking and around the house do-it-yourself projects. I have it found it to be a rugged, very well made tool that also has good balance. Indeed, it is an easy to use tool that takes the drudgery out of sanding.

It can be used for aggressive sanding with the coarse grits, such as in the prep work for painting plaster walls, or it can be used for the finish sanding of cabinetry of furniture. It performs equally well at either task.

I strongly recommend that one should also purchase the vacuum hose adapter, particularly since this sander can generate a lot of dust.

Pretty much anyone who does any sort of woodwork at all needs a random orbit sander. There are, however, many different brands and features to choose from. I settled on this Bosch unit because of the features. And also because the Bosch brand is clearly very competitive.

Because I use this sander mostly for furniture, I wanted a 6" pad size as that should be easier to keep flat than a 5" size. The 6" units are more expensive and heavier than the 5", but not by much.

Another feature worth having is the use of hook and loop sanding disks. I spent a lot of years in body shops where we used spray adhesive, glue and self-stick disks. What a mess. Horrible. And I used these sanders at home for my wood projects. Believe me, the hook and loop, velcro-like, units are much better and are so easy to use that you are more likely to use the correct sanding pad rather than to just use whatever is on there.

I also wanted good dust control via a vacuum system. This tool is easy to hook up to a 1 1/4 hose with the appropriate Bosch adapter. My dust control system is set up so that the vacuum activates when the Bosch is turned on. Air is sucked through the holes in the sanding disks (I have been using the Mirka brand), through the pad and out the back port where the filter was.

That self-contained filter comes right off to expose the suction port for the vac. I have no experience with the supplied filter, so cannot comment on it. I can say that there is almost no dust at all with the vac system and that sanding is actually easier because the vacuum sucks the sander to the board and you do not have to press down so hard. Still, you should use a dust mask.

I've had the opportunity to use a number of 5" and 6" RO sanders over the past few years and this is one I would definately buy again. Smooth, well balanced and fits my hands well. I bought mine with the vac adapter and Bosch's hose. I use it hooked to my Shop-Vac and it works very well. I can't see any dust on my bench around where I am sanding and I don't smell any either. 6" paper is now available at the box stores if you want to go that route (I prefer the Mirka available here). I like the 6" simply because it takes less time to sand an area.

This is a great sander and it is extremely powerful. When it is on full it is very aggressive. When it is on low it is very gentle. It has nice handles and it is easy to hold and control. The dial that controls the speed stays where you put it and it is placed so you won't bump or move it while sanding. The trigger has a lock to keep it running. The pad is soft and doesn't damage what your sanding. The hook and loop system works great and holds the disc very tight.

The filter that comes with this is useless. I used it for the first couple days and it did not catch much of anything and the air was still full of dust. This should just come with the adapter to attach a vacuum. The adapters that you can buy will only fit a bosch 35mm hose. If you have a shop vac or other vacuum that uses a standard size hose you will need at least three adapters to make it fit this sander. So far I have the rs006 that attaches to the sander and vac020 which attaches to my 2 1/2" hose. These do not fit together so now I need to find another adapter to connect my adapters if I want them to fit right. I don't think I should have to buy $30 worth of adapters for this to work with my shop vac. I ended up just modifying what I had to make it work.

Don't buy a bosch tool with a dust port unless you own a 35mm hose to attach to them. If I knew this about Bosch I would have purchased another brand.

I took on a job stripping, sanding, and painting about 100 kitchen cabinet doors for a apartment property renovation. Not having the 16 scfm @ 90 psi through my compressor for an air sander and not wanting to have my hands go numb using the various electric sanders I already have, I purchased this sander on the high recommendations of others.

This is a high-quality tool and definitely relieves some of the drudgery of sanding. The 6" pad makes quick work of anything it touches. The variable speed gives you the opportunity to adjust to changing surface conditions. Dust collection through the provded filter or through a vacuum host is very efficient. And my hands aren't numb anymore.

Cons - a bit heavy to use with one hand for anything except short periods of time. It's large - smaller than a belt sander, larger than a low-end RO sander. Paper selection limited.

Considering getting rid of the two PC "buzzing bee in your hand" sanders but, being smaller, they're more useful in the tool bag. The Bosch will stay at the shop.


Still going strong and still my favorite sander. Been dropped a couple times but has never stopped working. You can buy the 6-hole, 6-inch Mirka paper here at Amazon but, if you search around other woodworking retailers, you can find additional Mirka 6-inch products (Abranet, Royal Gold) that will broaden the use of this fine sander.
