PFERD thin wheels cut faster than conventional wheels, leaving a cleaner cut, with minimal burr. Ideally suited for thin gauge sheet stock, thin walled tubing and small diameter cross sections. Material should always be cut at a right angle to the work piece. Larger work pieces require thicker PFERD cut-off wheels for improved lateral stability. PFERD Thin Type 1 wheels are fully reinforced, and conform to U.S. safety standards as well as more stringent European safety standards.
