14″ Airway Buffing wheel with a 5″ center. 1-1/4″ arbor hole to fit on the most common wheel polishing machines. Will also fit securely to an arbor of 1-1/4″ for an industrial lathe.
We always recommend when polishing to use two yellow 14″ airways in the middle and two orange airways on the side. The orange airways are slightly stiffer and produce a (slightly) stronger cut. The orange are also 20 ply while the yellow are 16 ply giving a larger surface face width for cutting wheels.
