The 390K is a powerful, compact sander ready to take on a variety of heavy-duty jobs. It's ideal for aggressive sanding, coating removal, leveling seams, smoothing rough material, solid surface work, and boat-bottom cleanup.
ENDURATECH Motor for Improved Productivity and Durability
The 2008 winner of the WOOD Magazine Top Tool Award, the 390K boasts ENDURATECH brushless motor technology for 70 percent fewer wearable parts, which increases the motor life by up to 10 times when compared to traditional palm-grip sander motors. The result is greatly improved productivity, durability, and control.
Low-Profile Design for Optimum Control
The 390K sets a new standard for palm-grip sanders. Its low-profile design is 30 percent shorter than the competition. This means you'll get optimum control and finish, as well as comfortable handling on the job.
Variable Speed Range for Versatility and Precision
Versatile and powerful, this sander has a variable speed range of 7,000 to 12,000 rpm for optimal removal rate on a variety of materials. Electronic load-control monitors the rpm and maintains a constant operating speed for smooth sanding and over 40 percent faster material removal.
Innovative Brake Designs Save Time and Reduce Free-Spin
Also, the 390K saves you time with its innovative electronic motor brake, which reduces spin-down waiting from close to 10 seconds to approximately 3 seconds.A separate mechanical pad brake reduces free-spin--effectively putting an end to gouging, and a 3/32-inch orbit diameter means this sander can handle a range of materials with ease.
Compact, Ergonomic Design with Integrated Dust Port
The 390K measures 4 by 5 by 12 inches (W x H x D) and weighs just 2.1 pounds, so it's compact and easy to store. Its rubber grip and ergonomic features maintain user comfort, even during extended jobs.
For further convenience, an integrated dust port accepts 1-inch and 1-1/2-inch vacuum hoses for optimal dust collection. This makes your workspace cleaner and healthier and helps maintain good visibility of your workpiece.
The 390K is backed by a three-year warranty.
