16" x .155" x 1"/20mm arbor cutting wheel for large chop saws or freehand saws. Lasts 25-50x times longer than conventional abrasive cutting discs. Reduces amount of sparks, saves time on changing blades, and doesn't shrink in size during the cutting operation. Excellent for cutting foundry gates, sheet metal, pipe, metal plate, metal tubing, angle iron, caston iron, ductile iron, ceramics and metal studs. Note: Blades are optimized for cutting metal 3/8" thick or smaller. Larger sections of metal will reduce life to 5x-10x that of a conventional abrasive.
