Tiger Aluminum 6 inch type 27 combo wheels are specifically designed for high performance cutting and grinding and extended wheel life on aluminum. These wheels blend abrasive grains with Weiler’s non-loading formula, resulting in a fast and consistent cut rate on aluminum. Combination wheels offer flexibility and efficiency when switching between cutting and grinding applications with a right angle grinder. The 5/8″ – 11 nutted metal hub allows for quick spin-on, spin-off changeover and eliminates cross-threading or sticking to spindle due to heat build-up. Non-loading formula keeps the wheel from gumming up, allowing operators to get more work done in less time without compromising durability. Silicon carbide and aluminum oxide blend delivers a consistently high cut rate throughout the life of the wheel. Contaminant-free wheels deliver a worry-free solution for aluminum applications.
