Tiger® Zirc® 3 in type 1 cutting wheels cut faster and last longer so you get proven productivity at an exceptional total cost. The self-sharpening zirconia alumina grains retain a high cut rate throughout the life of the wheel while a hard bond delivers long wheel life for heavy duty applications. The flat type 1 profile allows for deep cuts commonly required when cutting metal. The 0.035 in wheel thickness is ideal for cutting tubes, bar stock, and large cross-sections with a die grinder. The 3/8 in open arbor offers a cost-effective mounting option when using adapting nuts. These wheels are designed for hardcore metal fabrication professionals who need a high performance solution when cutting steel, structural steel, and iron.
