The KATSU Tools FIT-BAT 18V / 21V Cordless File Belt Sander (SKU: 102715) is a versatile, precision detailing sander engineered for deburring, shaping, and finishing work on wood, metal, plastics, and tiled edges. Powered by a high-torque motor delivering variable belt speeds from 280 to 480 m/min, this portable finger sander allows fine speed adjustment to suit various material hardnesses. It features a pivoting ±45° adjustable sanding arm that reaches effortlessly into narrow gaps, tight corners, and awkward angles where traditional sanders cannot fit. Equipped with a tool-free belt tensioning system for quick swaps and an integrated dust extraction port for a cleaner workspace, this lightweight tool comes supplied with 3 sanding belts (457 x 13 mm, 80 Grit). As part of the KATSU Tools FIT-BAT system, it is compatible with standard 18V and 21V slide-on lithium-ion batteries (sold separately).
Variable Speed Control (280–480 m/min): Electronic speed dial provides precise control to match the belt speed with specific timber, metal, or composite finishing tasks.
±45° Adjustable Sanding Arm: The pivoting arm adjusts up to 45 degrees in both directions, making it ideal for tight crevices, curved surfaces, and intricate detail work.
Tool-Free Belt Installation: Quick-release mechanism enables rapid, tool-free installation and alignment of 457 x 13 mm sanding belts.
Integrated Dust Extraction Port: Connects directly to external dust collection hoses to pull away airborne particles, maintaining line-of-sight and a clean working space.
