PFERD Whisper SG-Plus grinding wheels
With very aggressive stock removal rates, PFERD’s new Whisper SG-Plus reinforced grinding wheels also increase user comfort levels and productivity results.
This combination of maximum performance features effects a substantial savings in labor costs while greatly improving working conditions. Made with a patented design that produces very soft, quiet grinding with lower vibration and dust levels, Whisper wheels are ideal for high volume grinding where high quality surface finishes are required and can replace any conventional grinding wheel for increased productivity.
This productivity innovation is designed to work on angle grinders in all output categories for surface grinding of weld seams and fillet welds. The SGP Whisper is available with Aluminum Oxide grain for grinding steel and stainless steel and the SGP Whisper ALU version is available for grinding aluminum. These depressed center wheels (Type 27), in 4 1/2” and 5” diameter sizes, feature both unthreaded 7/8” arbor hole and threaded 5/8 - 11 styles. Their noise reduction level has been measured at 90% as compared to conventional grinding wheels and vibration reductions have also been charted with similar improvements in limit values.
