PFERD Comb click fiber disc for general-purpose grinding, from coarse to fine, in diverse applications (industry, trades, DIY). Comb click system combines an innovative flexible backing pad with a quick, easy and rugged mounting system on the back of the disc. The backing pad allows Comb click discs to be used with standard angle grinders. The geometry of the cooling slots ensures a high throughput of air, thus significantly reducing thermal loads on the abrasive material and work piece. The rugged mounting fixture, secure disc attachment to the backing pad plus optimized cooling help to provide: up to 30 percent lower work piece temperature, up to 25 percent increased stock removal, up to 30 percent longer service life and improved utilization of abrasive product and up to 30 percent less tool wear. Pferdergonomics recommends Comb click as an innovative solution to sustainably reduce vibration, noise and dust levels produced in the workplace, and to improve working comfort. Pferdefficiency recommends Comb click for long, fatigue-free and resource saving work, with perfect results in the shortest possible time. The patented quick-mounting system reduces disc change and setup times. Specification: Diameter: 5"; Max RPM: 12,200; Grit: 36.
