National’s 165mm blast wheel kit fits on the A95, A96, and A97 shot blasters.  This is a regular wear part for shot blasters and should be kept on hand to quickly replace on large jobs.  

A general rule of thumb is that blast wheels should be replaced or inspected after about 40 hours of work.  Cleaning and prepping a concrete floor with a shot blaster is an easy one-step process, made easier when you have the right wear parts on hand.
