SurfPrep’s 3″ x 4″ Electric Ray Sander
Powerful. Efficient. Engineered to Perform.

The 3″ x 4″ Electric Ray Sander is built for professionals who demand precision, durability, and performance. Designed with advanced features and robust construction, this tool delivers exceptional results across a variety of sanding applications.

Key Features:

  • Three Speed Settings
    Operates at 4,000, 7,000, and 9,000 RPM—perfect for everything from delicate finishes to aggressive stock removal.

  • High-Torque Brushless Motor
    Outer-runner motor design with larger magnets provides superior torque and power efficiency compared to traditional inner-runner motors.

  • Energy Efficient Performance
    Significantly reduces energy costs compared to pneumatic systems—without sacrificing performance.

  • Rugged & Reliable
    A patented rubberized seal protects the internal computer board from dust, debris, and environmental damage—ideal for harsh job site conditions.

  • Advanced Cooling System
    Patented spindle bearing fan enhances motor longevity by maintaining optimal internal temperatures.

  • Integrated Safety Features
    Two built-in override protection programs ensure long-term reliability and extended tool life.

  • Dust-Free Sanding
    Compatible with SurfPrep’s POV-8 AND PIV-12 HEPA Dust Collection System or most standard shop vacuums. See related products below for options.

Notice: The SurfPrep Sanding System is designed to work as a complete system whereby SurfPrep branded sanders connect to and operate with SurfPrep branded dust extractors. Customers have successfully connected SurfPrep sanders to other brands of dust extractors without incident of static electricity and maintain full functionality of auto on/off features. SurfPrep sanders can easily connect to DIY STYLED vacuums with parts we provide. However, in these cases SurfPrep DOES NOT guarantee freedom from static electric shock. Often this occurs when lower priced DIY vacuums do not have the appropriate grounding components to prevent static shock. SurfPrep fabricates all sanders & dust extractors with static conductive components.

Less effective than advertised at sanding rounded edges on ply/mdf

Less effective than advertised at sanding rounded edges. Works slightly worse for what I'm doing than an orbital with an interface pad, AND costs significantly significantly more. Unfortunately realized my mistake after the 30 day refund :(

Great So Far!

I was intimidated by it at first because it’s so different from a 5 inch random orbital sander. Today is the first day I gave my 3x4 a real workout, and I loved it. A couple of times I wondered what I had done without it in the past. I need to try out all of the abrasives and figure out what I like. Everything is excellent so far. I’m very happy with my investment.

Awesome Product with AMAZING Customer Service

I purchased the 3x4 Electric Sanding System to refinish the golden oak in my 1998 kitchen and bathrooms, and I am incredibly impressed with its performance! It's so easy to use, and the variety of items included in the kit made it perfect for getting started on my project.
They also have an AMAZING customer service team!! I encountered an issue while trying to use two MasterCard Gift cards for my online purchase, but the system wouldn't allow two methods of payment. The team worked diligently to find a solution for me. The workaround was to purchase two SurfPrep Gift Cards, they merged them over the phone which allowed me to complete my online order with ease.
I have watched a lot of DIY content on YouTube, I've noticed that many creators I follow use SurfPrep products, and now I completely understand why. If you're thinking about purchasing one but are not sure if it's worth the cost...I can tell you for me, it was 100% worth every penny!
Thank you for a fantastic product and exceptional service.

Great Buy. I am not a professional but I am currently refinishing my kitchen cabinets and I refinish furniture for fun. This sander has really helped with the kitchen cabinets because I am not removing them but leaving them up!
