Sandwox 6" Brushless Electric Sander, 5mm Random Orbit, 400W, SX655US
Product Overview:
Sandwox SX655 5/150 6" (150mm) Brushless Electric Vacuum Ready Sander with 3/16" (5mm) Random Orbit, 400W (SX655US) 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.
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.
The 5mm (3/16") random orbit makes this sander perfect for all tasks, ranging from coarse and intermediate sanding to pre-polishing materials such as wood, varnish, primer, filler, paint, epoxy, fiberglass, composite and solid surface materials.
Features a bright LED Light with an independent on/off switch to help illuminate surface in dim sanding conditions when desired.
The enlarged on/off switch located at the front of tool eliminates the need for a clumsy paddle allowing for more user control of the sander in different positions. This 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. 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.
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.
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 Sandwox SX655US includes the BH-65 6" Medium Multi-hole Grip Backup Pad with M8 male thread and medium density. The specially designed backup pad features 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), sold separately.
