"Weiler Wolverine 9 inch type 27 combo wheels deliver a fast cut rate and consistent performance at a good value when cutting and grinding steel and other metals. Combination wheels offer flexibility and efficiency when switching between cutting and grinding applications with a right angle grinder. 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. Wolverine is an aggressive, get it done product line for everyday general purpose use. Weiler's Combination Wheels offer flexibility and efficiency when switching between cutting and grinding applications. Our Tiger reinforcement technology provides the strength to hold up when grinding, while maintaining a fast cut. Weiler's value line is manufactured using similar product construction and the same exacting standards as other Weiler power brushes, but engineered to provide cost-effective use in less demanding environments. Wolverine brushes (Formerly Vortec Pro) are an economical choice for the construction trades, low volume production shops and light duty industrial MRO use."
