The product we would like to introduce from our main product line of mold grinding wheels is the 'YTM'. The 'YTM' is a resin-based grinding wheel developed for the final finishing and mirror polishing of molds.

It is ideal for corners and grooves that are difficult to polish with paper, and it achieves more than five times the gloss compared to ceramic grinding wheels. The grinding wheels are color-coded by grain size, making them easy to manage, and they can be safely used for polishing non-ferrous metals. There are two types of hardness for the grinding wheels: hard and soft. *Due to being a combustible solid, please ensure that the grinding wheels are dried naturally. This can cause a fire hazard. Currently, we are offering free samples, so please feel free to contact us for more details!! ↓↓↓
