Mirka® FBS-B Battery File Belt Sander

Cordless convenience for grinding spot welds and seams

The cordless Mirka® FBS-B 10 and 13 file belt sanders are designed for collision repair, spot welds or seams or removing rust or paint.

Grind everywhere you have to go

Complete Freedom

The cordless design of the Mirka® FBS-B battery file belt sander means you have complete freedom to work without restriction from cables or hoses, making every spot weld, welding seam or rust spot accessible.

Mirka offers two models of the FBS file belt sander: the FBS-B 10 and FBS-B 13. Choose between a narrower or a wider belt version depending on your application.

The Mirka FBS is lightweight and balanced, making it comfortable to hold for long periods. With the battery, the Mirka® FBS-B 10 sander weighs only 2.5 pounds, reducing strain especially in difficult working positions.

Body repair, manufacturing or restoration

Effortless Grinding

The balanced and ergonomic design is free from cables or hoses, with a rubberized handle that is comfortable to hold. With the open belt access and tension mechanism, the belt is easy to change in a matter of seconds, and the arm angle of the tool is quick to adjust.

Save time and energy

Brushless Electric Power

With a powerful and long-life brushless electric motor, the smooth, quiet, and lightweight Mirka® FBS-B file belt sander makes easy work of tough jobs without the need for a pneumatic compressor. On a yearly basis, a cordless tool saves a significant amount of energy compared to a pneumatic equivalent.

Designed for convenience with an easily swapped battery, the Mirka® FBS-B file belt sander minimizes downtime and maximizes productivity in manufacturing and repair work. The batteries share their design with other Mirka cordless tools, including cordless sanders and polishers as well as the Mirka® ANGOS cordless grinder.

Clever design and connectivity

Designed for Safety

The Mirka® FBS-B file belt sander is designed for operator safety. It features a light to improve sanding precision and the handle includes a protective flap to shield the operator’s hand from sparks. Together with the easily controlled stepless trigger, sanding speed is easily adjusted between 2200 rpm and 17000 rpm with the handle-mounted buttons that are familiar from other Mirka cordless tools.

Thanks to Bluetooth® connectivity, the Mirka® FBS-B file belt sander is paired with the myMirka® mobile app that helps operators monitor vibration levels and to register their tools.
