This polisher is manufactured in Japan and is regarded as one of the finest available in the market. 
The polisher is equipped with a spindle lock that removes the necessity of using a wrench to detach backer pads or diamond tools. When pads are secured with a wrench, they can occasionally become misaligned, leading to premature wear of the machine. Therefore, the spindle lock not only operates more efficiently but also ensures that the backer is attached flawlessly every time.
Additionally, it is crucial to invest in a high-quality backer, which significantly reduces the stress on the machine. Lastly, it is essential to expel water from the machine each night and apply lubrication.
