Mini Electric Belt Sander with Variable Speed

Compact Belt Sander for Precise DIY Polishing and Sharpening

Get reliable, consistent results on metal, wood, and plastics with this mini electric belt sander. Designed for detailed work in small workshops or home garages, it delivers controlled grinding, polishing, edge shaping, and knife sharpening without taking up much bench space. Its adjustable worktable and variable speed control make it suitable for everything from rough shaping to fine finishing.

Built around a 304 stainless steel body, this sander offers solid stability and long-term resistance to wear and corrosion. The abrasive belt runs on wheels with built-in double bearings for smooth, non-slip operation, while the motor also uses double bearings to support high speed and high torque. Speed is adjustable across 7 levels, with a working range of approximately 4000-9000 rpm, so you can match the belt speed to the material and task. The three-position switch supports forward and reverse rotation, giving you extra control when sharpening or working in tight spots. An adjustable-angle worktable lets you set up accurate bevels, and a fixed 15° sharpening guide helps achieve consistent knife edges. The included power supply accepts 110-240V~ 50/60Hz input and provides selectable DC output (12/15/16/18/19/20/24V) for stable motor performance.

The machine is equipped with anti‑vibration, height‑adjustable foot pads for stable, low-noise operation on a bench. These pads can be removed if you prefer to bolt the sander directly to a table or wooden base for a more permanent setup. A dust‑proof cover helps shield the motor from debris, supporting smoother operation over time. The abrasive belts use uniform grit that is resistant to shedding and designed for longer service life. You receive 10 belts in assorted grits (120, 320, 600, 800, 1000 - two of each), allowing you to move from aggressive material removal to fine polishing on the same machine. A polishing wheel is also included, with color sent at random.

• Sturdy stainless steel construction, double‑bearing wheels, and dust‑protected motor support smooth, reliable operation over time.
• 7‑speed control, forward/reverse switch, adjustable worktable, and included multi‑grit belts give you precise control over finish quality.
