Bosch has introduced a new half-sheet orbital finish sander (OS50VC) that they say will provide woodworkers with superior handling and maximum comfort during long sanding sessions.
The sander is said to feature superb vibration control, a convenient sandpaper clamping system, and high performance 3.4A power rating.
Vibration Control and Dampening
Bosch’s “best in class” vibration control and dampening is accomplished via a suspension system that includes eight foam blocks that isolate the grip area of the tool from the motor and gearing. This prevent tool vibrations from transferring to users’ hands.
Higher power usually translates to quicker sanding performance, and this case is no different. The 3.4 amp motor is said to be significantly more power than competing models, which should result in speedier sanding and paint removal.
The OS50VC sander has a Sheetlock paper clamping system that automatically tensions the paper as it’s being clamped. This way the paper is held completely flat against the sanding backing pad. The backing pad itself is extra soft, allowing it to accommodate contours and unevenness.
I have an older Bosch 1/4″-sheet finish sander, and LOVE the clamping system. It’s easy to attach paper to the sanding plate, and a quick punch creates holes for dust removal.
Included is a translucent microfilter dust canister with integrated paper filter and cap. The canister is quickly emptied via an easy-to-remove twist-off top.
The sander also comes with an included hose connection, for use with dust extractors or shop vacuums.
- variable speed dial: 8,000-11,000 orbits per minute (OPM)
- multiple soft-grip locations for fatigue-reducing ergonomics
- removable auxiliary handle for flexibility to sand in tight spaces
- due-cast aluminum gear housing for improved tool life and stability
- can also accept PSA (sick-on) sanding sheets
- made in Switzerland (according to Amazon product description)
Pricing and Options
MSRP is $379, and you can find the sander via authorized USA Bosch dealers. An optional L-Boxx with foam inlay is available separately.
By Now(via Amazon)
I’ve used belt sanders, random orbit sanders, 1/4″ sheet sanders, oscillating tool sanding attachments, and all sorts of hand sanding products and accessories, but no half-sheet sanders.
It seems to me that half-sheet finish sanders are akin to 1/4-sheet sanders, but with added power and surface area for quicker sanding or paint removal tasks.
The price seems a little steep, at least compared to Bosch’s other power sanders, but it could be easily justified if Bosch’s vibration control system is as effective as they claim.
