PURUI 12 Spindle Adapter Right and Left Hand for 6 Bench Grinder

This set of spindle adapters allows you to attach buffing and grinding wheels on a motor shaft without requiring washers and nuts. They have a tapered threading LH and RH and work for wheels with starter holes of different sizes. Moreover, the spindles feature a spinning force to keep the wheel securely in place, and they also deliver more working space compared to others in the same category. The spindles are 4 3/4 inches long, come in 1/2 inch and 5/8 inch diameters, and fit on threaded and unthreaded shafts. They are also suitable for treated buff and grinding wheels, including the Beall buffing wheels. Customers have mostly given positive feedback for this product. They appreciated the convenience of not having to use washers and nuts and the added space to work with, and many have reported that they fit well on their grinder motor shafts. The spindles are also said to save time and work as expected. However, some customers have reported the spindle's hole being larger than expected and having some play on the shaft, which required careful positioning to make it usable. Additionally, one customer has reported low-quality steel and returning the product, while another reported that it did not fit their shaft because of rust.
