Review: Good Product but design could be better - nice little unit! design could be improved bit by extending the threads on polishing and abrasive wheel to give you enough room to use it with out the belt or the motor getting in the way but overall works as intended. price is good tho
Review: Great price and good quality. - I watch way too many knife-making videos, and let’s be honest—I have absolutely no idea what I’m doing. But hey, I justified my purchase with the classic excuse: “I can use it to sharpen my lawnmower and tiller blades, and all my knives!” As a novice’s apprentice, I’m basically the awkward kid in shop class who can’t figure out which end of the hammer to hold. So, I decided to buy the Model 1, 3-in-1 Mini Belt Sander. I don’t know why I was nervous about using it; it seemed simple enough. Well, the buffer and sander are pretty self-explanatory, but that grinding wheel? Let’s just say it takes a bit of getting used to. I tried it on a machete, and let’s just say my grinds looked like they were done by a toddler with a crayon. But hey, practice makes perfect, right? Bottom line: my limited knowledge doesn’t exactly qualify me to judge this product like a master craftsman. But as someone who values their hard-earned cash, I can confidently say this is a great product—perfect for any budget and compact enough to squeeze into my cluttered garage, which I like to call my “wannabe workshop.” I’ve been using it consistently for the past month, and it’s still holding up like a champ. So, if you ever need a sander that can handle a novice’s mishaps, this one’s got your back!

## Features

- 🏆【Sailboat Model】: As you can see, the sanding belts are presented like vertical boats, which means a longer area of vertical sanding belts with good cushioning, which is very helpful for hand work such as jewelry that does not require excessive speed.
- 🏆【Plus Kit】: By installing a grinding wheel and a buffing wheel on the left and right side of the belt sander, a mini bench grinder with sanding belts can be built up quickly, and with the 7-speed adjustment function it will be a super tool for jewelry making, resin artwork, and knife making.
- 🏆【Speed Adjustment】: Sliding the slider on the power adapter can achieve 7 gears of speed switching, from the lowest to the highest speed switching is very convenient, press the button next to the power supply can also switch the sand belt forward and reverse.
- 🏆【Sturdy Body】: The whole structure of the mini belt sander is made of heavy-duty stainless steel with 4 anti-vibration rubber feet at the bottom, which is excellent for use at home or in the outdoors.
- 🏆【Powerful Motor】: All copper motor with high torque, strong power and low noise. Can reach 4000 to 9000 rpm in a minute, can cope with a variety of needs including metal, jewelry, plastic resin, knives, etc.
- 🏆【Note】: If the machine does not respond when the switch is turned on, try plugging the power adapter and access port firmly; installing and using the grinding wheel at high speeds may result in greater vibration, so you can use a clamp to secure it to the table so that the machine will run stably.
