MORE POLISHING WHEELS FOR YOU! - Comes with white cotton wheel*2, yellow cotton wheel*2 and fiber wheel*2. White cotton is softer for polishing metal parts or jewlery. Yellow cotton is harder for polishing large metal areas and mirror effect. Fiber wheel is for Rust removal, metal workpieces or wooden. 1750-10000RPM ADJUSTABLE SPEED - No waiting for startup! The motor starts up in 0.1 seconds, and you tweak speed from 1750RPM (for soft jewelry chains) to 10000RPM (for hard metal components), so it won't struggle with tough jobs. Polish everything from delicate necklaces to heavy machine parts. STABLE WITHOUT VIBRATION - No more wobbly polishing! The heavy cast iron base cuts vibration, so your work stays smooth (no scratches from shaky wheels). 4 rubber feet grip wooden/plastic benches for light use; if you’re on a smooth desk, bolt it down via the 2 mounting holes – perfect for garage workshops or balcony DIY stations. MORE COMPACT THAN YOU THINK - It only takes up 0.01 cubic meters (about the size of a shoe box!) – small enough to sit on your garage workbench or balcony DIY table, no more crowding out your pliers, screwdrivers, or other tools. Perfect for quick jobs (like polishing a ring) or daily use – compact but never skimps on performance. POWERFUL BUT LOW NOISE - 320W is way stronger than 200W models (almost 1/2 horsepower) – no stalling even when polishing medium metal pieces. And it never overheats. It only makes a soft hum, so it won’t disturb your family if you're working in the garage. YOU CAN TRUST US - We stand behind this bench buffer with a 1-year warranty.
