About Us

Nearly 100 Years Of Manufacturing Excellence
With Quality At Its Best!

SPI-RAL Premium Grinding Wheel Dressers feature a unique principle of design and construction. The SPI-RAL Cutter is radically different from ordinary dressers. This patented cutter is made in a single, continuous-piece spiral which, when held against the face of a wheel, cuts across the exposed surface in an even-wiping action, rather than bumping of the grain, as is done with multiple-piece dresser wheels. The result is a perfectly dressed, true wheel, which will perform better and last longer, yielding subsequent replacement savings.

The foundation of many industrial products, from large to small, starts with foundries, casted or forged materials, and metal fabrication. With the production demands companies are experiencing today, material removal or trimming by cutting and grinding needs to be done as efficiently as possible to control costs. Whether your operations are hand held, pedestal, swing or floor-mounted grinding, keeping your grinding wheels true and clean is essential for faster material removal, increased efficiency, increased throughput, and reduced costs.
