HiKOKI Carbon for Grinder

- The logo will be changed to [HiKOKI] depending on the manufacturer's distribution inventory. Thank you for your understanding when purchasing. - Excessive wear on the carbon brush may cause motor failure, so when the length reaches the wear limit, replace it with a new one. Carbon brushes come in a set of two. When replacing, please replace both at the same time. Also, make sure to clean the carbon brush by removing any dirt so that it can slide freely within the brush holder.
