Sandwox 6" Brushless Electric Sander, 5mm Random Orbit, 400W, SX655US

Product Overview:

Meet the Sandwox SX655US, the next‑generation 6" brushless electric random orbital sander engineered for professionals who demand power, precision, and long‑term reliability and your next favorite tool! With a 5mm (3/16") random orbit, 400W high‑efficiency brushless motor, LED surface lighting, and industry‑leading dust extraction, this sander is designed for professional daily use and delivers exceptional performance across automotive, marine, woodworking, composite, and industrial finishing environments.

Whether you’re leveling filler, prepping primer, refining wood, or finishing fiberglass, the SX655US offers the perfect balance of cutting power, control, and comfort — all at a price that outperforms the competition. The SX655US includes the BH‑65 backup pad, wrench, vacuum hose/power cable clips, and connected 15' power cable.

The SX655 is built for easy sanding with one hand, resulting from a host of premium ergonomic features including its light weight, low-profile and compact size, lower vibration, LED surface lighting, enlarged on/off switch on front of tool, 11-level speed adjustment dial and multiple built in electronic protection systems.

High‑Efficiency Brushless Motor:

The 400W brushless motor delivers consistent power at speeds from 4,000 to 10,000 RPM. This motor requires lower power consumption and generates less heat vs. brushed motors, so it doesn't require added venting and preventing dust accumulating inside the machine, resulting in longer working lifetime. 

5mm (3/16") Random Orbit for Universal Sanding:

The 5mm (3/16") random orbit is the most versatile “do‑everything” stroke, preferred by professionals, it makes this sander perfect for all tasks, ranging from coarse sanding to intermediate leveling, to pre-polishing. Excellent for use on materials such as wood, varnish, primer, filler, paint, epoxy, fiberglass, composite and solid surface materials.

LED Surface Lighting:

Features a bright LED Light with an independent on/off switch to help illuminate surface — perfect for spotting imperfections, sanding in dim areas, or working inside vehicles and cabins.

Ergonomic One‑Handed Control:

Designed for long sessions with minimal fatigue, the enlarged on/off switch located at the front of tool (eliminates the awkward paddle) allowing for more user control of the sander in different positions. This is a huge ergonomic benefit that allows for easier one-handed sanding with less fatigue.

The 11-level speed adjustment dial is conveniently located on the side of the tool, much easier and faster to use than clumsy digital buttons found on competitor tools, relying on you to guess your speed. 

This is one of the easiest sanders to control with one hand.

Exceptional Dust Extraction:

As well as ergonomics and ease of use, the Sandwox SX655US is compatibility with 6" dust-free grip sanding abrasives. Combine the Sandwox SX655US with a Sandwox dust extractor and start sanding with dust-free abrasives for a safer and healthier working process thanks to efficient tool dust extraction.

The sander includes the Sandwox 6" Medium Density Multi-Hole Grip Backup Pad (BH-65) with specially designed exhaust and edge vacuum channels for maximum dust extraction. The tool also includes vacuum hose clips and backup pad changing wrench. 

The Sandwox SX655US vacuum connection is designed to utilize a 1.25" O.D. threaded hose. Consider using with the Sandwox 15' Antistatic Vacuum Hose (380003971) and pairing with a Sandwox LX1232 Premium Dust Extractor, each sold separately.

Premium Build Quality:

Internally, a multitude of advance features have helped to create one of the best professional electric sanders on the market. A new generation of German engineered high-power and high-torque brushless motor is used offering stronger performance and longer working lifetime. Independent motor cooling system and dust collection brings better heat dissipation and dust collection performance. The tool features a specially designed vibration balance system to ensure smooth and stable control. The self-developed circuit board was created with intelligent protection systems for complex and harsh working conditions, featuring triple protection for short circuit, over temperature and over current, and also includes multiple sealing protection systems.

The 5M (15') power cable is affixed to the tool, a much more durable design element than the detachable cables that frequently break on competitor tools.
