The S-PERF multi-hole is based on a string of numbers known as the SPERFnacci Sequence. As a hole pattern, the resultant spiral structure, which crops up time and time again in nature, provides superior dust extraction, significantly reduced clogging and therefore longer abrasive life.

Standard hole pattern

Complex, robot-assisted tests produced astounding results: Depending on material and application, S-PERF works four times longer than standard abrasive discs.
