SurfPrep's 3" X 4" Electric Ray is power packed with 3 speeds (4,000, 7,000 & 9,000 RPM). It's brushless outer-runner motor is constructed with bigger magnets, providing greater torque which saves energy compared to inner-runner motors. The tool's computer board is completely protected with a patented rubberized seal preventing environmental contamination. Patented spindle bearing fan enhances life by keeping motor & bearings at a lower temperature. Electric Ray Sanders have significant energy cost savings compared to pneumatic sanders as well as two override protection programs to enhance the life of the tool.

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

7. Frequently Asked Questions 

What is the SurfPrep 3x4 Electric Ray sander used for? 

The SurfPrep 3x4 Electric Ray sander is a rectangular electric orbital sander for corners, edges, profiles, trim, shaker doors, and any surface a standard round sander cannot reach without rounding edges or losing contact. It is used in cabinet finishing, furniture making, and detailed woodworking applications. 

What speeds does the SurfPrep 3x4 Electric Ray have? 

The SurfPrep Ray sander has three speed settings: 4,000, 7,000, and 9,000 RPM. The lower setting suits fine finishing and between-coat passes. The mid setting handles most general sanding tasks. The high setting is for faster material removal on raw wood and initial prep work. 

Does the SurfPrep 3x4 Electric Ray come with abrasives? 

No. The electric sander does not include abrasives. It is available with or without a tool box. For abrasives, SurfPrep’s 3"x4" ProFoam pads and film and paper abrasive sheets are compatible with the Hook and Loop backup pad. 

Can the SurfPrep 3x4 Electric Ray connect to any dust extractor? 

The SurfPrep 3x4 Electric Ray sander includes a central vacuum conversion piece with a 1" diameter female cuff for compatibility with any central vacuum system. SurfPrep recommends pairing it with SurfPrep’s Vortex HEPA dust extractor system for guaranteed static-conductive performance. 

What is the difference between the tool box and no tool box variants? 

The tool box variant includes the SPTOOLBOX-3X4, which has a foam cutout for one 3"x4" sander and slots for organizing film and foam abrasives. The wood sander itself is identical in both variants. Purchasing a sanding system with the tool box saves 5% on the tool box price.
