08K3607 - Mirka DEOS II 3" × 4" Electric Sander, 3mm Orbit
This item is not available for this region.
With a tight 3mm orbital pattern that leaves smooth, even surfaces, combined with a compact 3" × 4" platen that permits precise sanding right up to an edge, this is a superb sander for finishing work. Its ergonomic design makes it highly maneuverable and comfortable to operate for long sessions, while the platen’s bevelled sides help avoid contact with adjacent surfaces when working into tight spots.
At 4" tall and weighing just over 1kg (2 lb 4 oz), it has a well-balanced, ergonomic design that makes it easy to handle. It’s compatible with a range of Mirka sanding pads, so you can select from a full line of abrasive types and grits to match the application.
Powered by a 14' grounded cord, its 250W brushless motor performs comparably to a 360W conventional motor. It has a low noise rating of 70 dB as well as low vibration output (3.3m/s²) and pairs with the myMirka app to monitor long-term vibration exposure, manage rpm settings and more.
Effectively dust-free in use, it has a rear port for connection to a 1" diameter vacuum hose, and a pattern of holes in the platen that draws dust from across the entire sanding pad, extracting dust right at the source to greatly reduce clean-up time.
In fixed-speed mode, you can lock in any of seven settings within its 5000 to 10,000 rpm range, with the paddle serving as an on/off switch to stop the tool within seconds. In variable-speed mode, the upper control paddle lets you adjust speed on the fly within each of the seven rpm ranges without interrupting your work; pressing the paddle increases the rpm, and a lighter squeeze slows the motor. In both fixed and variable modes, LED indicators tell you which rpm setting is in use.
A small sample of Mirka abrasive pads and a platen protector are included to get you started.
Efficient, precise and capable of yielding fine, consistent surfaces, this is an excellent finishing sander, backed by a 2-year warranty.
