With a continuous-duty motor, this heavy-duty office shredder is designed for high-performance and constant workloads. Shred paper, staples, paper clips and credit cards. Shredder shreds 14 sheets of 20 lb. paper at 16' per minute into 1/8" x 1-1/8" cross-cut pieces (security level 3). Two solid steel, cutting cylinders are subject to practically no wear and no sharpening and are made with a laser-cut and special heat-treating process for a more precise cut. Patented, V-TEK cutting-groove technology creates higher cutting capacity with lower power requirements. WhisperShred Technology reduces decibel levels so you experience a low noise level (59 decibels) whether running idle or shredding paper. Totally enclosed gear box helps reduce noise and prevents failure from dust and debris getting into the gears. Shredder also offers a 9-1/2" throat, photoelectric cell for automatic start/stop control, rocker switch for on/off and reverse, and removable 8-7/10 gallon waste bin.
