The Porter-Cable 4-Inch by 24-Inch Variable-Speed Belt Sander offers a powerful 12 amp motor and an all-metal design for durability and powerful handling. Ideal for both professionals, this heavy-duty sander boasts a large capacity, swiveling dust collection bag, a belt-tracking knob for quick-and-easy belt adjustments, and a variable speed dial for selecting speeds from 1,000 to 1,500 sfpm. Amp Motor for 20 Percent More Power The belt sander packs a powerful punch thanks to its 12 amp motor that provides more power than other Porter Cable sanders. Located directly over the platen for perfect balance, the motor gives you optimum control as you tackle large woodworking projects. For a steady flow of speed while you work, the efficient belt-and-gear system smoothly transfers power from the motor to the sanding belt. Variable-Speed Dial, Belt Change Lever, and Belt-Tracking Knob Enjoy precise sanding thanks to the variable-speed dial, which is conveniently placed on the rear of the handle, allowing for fast belt speed adjustments from 1,000 to 1,500 sfpm. Minimize down-time with the quick-release belt change lever and fingertip belt-tracking knob to dial in belt alignment over the rollers. Ergonomic Design and Large Dust-Collection Bag In addition to its advanced features, this belt sander is very user-friendly for a large, powerful sanding tool. Ergonomically correct handles keep you working comfortably, even during extended jobs. For further convenience, a large-capacity dust-collection bag swivels a full 360 degrees, so it’s never in the way.
