Size: Model.1 Universal Plus Kit


Color: Model.1 Universal Plus Kit


Features

  • Universal Model: As shown in the figure, the combination of the 4 bearings allows the sanding belts to exist at 4 angles, and the model is designed to meet the diverse production needs of craftsmen for a wide range of purposes.
  • 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 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.

Description

  • Tough, durable, well built.
Size: Model.1 Universal Plus Kit Color: Model.1 Universal Plus Kit
I made a couple of modifications, that made it even better. I super-glued the height adjustment screws to the rubber base so that I can adjust the height of all four corners. It is extremely well made and works better than I expected.

  • I would give it zero stars, if I could.
Size: Model.1 Universal Plus Kit Color: Model.1 Universal Plus Kit
If I could give it zero stars, I would. Ordered one. It broke after 1st use. Gave it the benefit of the doubt and got a replacement. That one also broke after first use. Spend your money elsewhere

  • Quality Comes in Small Packages: This Sander/Grinder/Polisher Get it Done!
Size: Model.1 Universal Plus Kit Color: Model.1 Universal Plus Kit
This inexpensive, very compact device does what you need it to do and it seems like it will hold up over time to keep on doing what you need it to do. I was impressed by the design and apparent quality of components. Time will tell if longevity is a part of the quality, but for now it appears to be so. Belt sander, grinder, polishing wheel are all included. A circular saw blade may be attached at optional cost. The "brick" style power cord includes an 8 position switch to select rotational speed of all three features; sander, grinder and buffer. The electrical components all seem to be good quality. ... show more

  • Fun to Use -- Decent Quality
Size: Model.1 Universal Plus Kit Color: Model.1 Universal Plus Kit
I have had this tool for 6 months and it has been fun to use. It gets "only" three stars because it is limited in the application lacking power--but that is what one should expect with a tool like this. I like its versatility--grinding, shaping and polishing small objects. It doesn't have a great build quality, but certainly good enough for the price. ... show more

Easy to set up and works as designed. This thing is very small though, it works for me but I underestimated exactly how small it is.
