Small enough to fit in the palm of your hand, yet powerful and precise enough to perform, the Astro ONYX Micro 2" Random Orbit Sander, Velcro is a must-have in any automotive finisher’s toolbox. This tool minimizes the working area for minor blemishes and fixes, expediting finishing time and conserving materials.

Exceptional power

Operating on a random orbital axis, this sander travels a full 3mm during orbits, ensuring a better finish when spot sanding. The full length of its pads measures 4.3”, making it optimal for tight spaces and smaller working areas, further concentrating its effectiveness and improving the results of spot sanding. Don’t be fooled by its small design: a free speed of 16,000rpms makes this a deceptively powerful tool!

Because it doesn’t utilize much air (3.1cfm), this is a great tool for smaller operations where a full-size air compressor isn’t necessary or available. It’s a great at-home tool, yet can stand up to the consistent use of commercial automotive settings.

Ultra-compact design

This sander uses ONYX’s latest technology in ultra-compact, precision-machined internals. Despite fitting neatly in your hand, the unit kicks out enough power to remain controlled while delivering enough force to rapidly bevel and sand.

Control is furthered by the ergonomic design of the tool. Because it’s controlled with your hand positioned atop, instead of parallel to the sanding surface, it’s easier to trace orbital patterns and square up work areas. Moreover, the speed control is located under the lever at the base of the pin, making adjustments quick and non-interruptive to your work.
