Bosch 3727DVS 6-Inch Variable Speed Dustless Random Sander

Amazon.com The 3727 random-orbit sander--one of the new breed of Bosch sanders--has at its heart Bosch's dual ball bearing and die-cast-base pad-dampening clutch. This system works to make the sanding pad rotate and orbit gradually as pressure is applied to the work surface. Aside from being a mouthful, this system is supposed to help materials achieve a "swirl-free finish"--and it does. Several orbital sander manufacturers are promising a swirl-free finish from their sanders, but Bosch comes the closest to meeting that promise. The 3727 adjusts from 4,500 to 12,000 opm (orbits per minute), with a variable-speed dial that's convenient to adjust but positioned to prevent accidental speed changes. In testing, we found this to be an exceptionally stable sander that never felt wobbly, even at full speed. This is a performance feature that should make the Bosch especially appealing to solid-surface finishers and Coreon-top installers. And, as with all of the new Bosch tools we've tested, this sander is comfortable to use. Front and rear handles are ergonomic and seem to fit naturally to the hands. The tool runs quietly and without much vibration, all of which means less user fatigue--an important consideration for production sanding applications. Although we didn't get to crank up the 3727 on any really large jobs, we definitely got the feeling it could cover a lot of ground. This Bosch is designed with pro use in mind, and that's reflected in the price. Although it's one of the most expensive sanders in the class, pros and do-it-yourselfers alike will find that extra money well spent. --Mark McDonald
