Tiger Aluminum Back 4.5 inch conical flap discs are the benchmark for the pipeline industry, providing rigid support for maximum aggression when grinding steel and stainless steel. These wheels are ideal for removing heavy pitting and resists rolling the pipe bevel ends prior to welding. The aluminum backing also prevents the disc from catching on the bevel when grinding.
The type 29 conical disc shape maximizes surface contact when grinding between 15° – 35° for aggressive stock removal on flat surfaces while the 60 grit abrasive grain is ideal for edge beveling, chamfering, weld grinding, blending, deburring, deflashing, and rust removal with a right angle grinder. Aluminum backing provides rigid support for maximum aggression and is recyclable. Self-sharpening zirconia alumina (ZA) grains hold up under high temperatures and extreme pressure. Contaminant-free (contains less than 0.1% Fe, S, Cl). 7/8″ open or plain arbor offers a cost-effective mounting option when using adapting nuts. Best on carbon steel, structural steel, stainless steel, and cast iron.
