Micro Grinders (Electric)

Micro grinders (electric) are tools that perform grinding and polishing with tip tools attached. They are suitable for work such as deburring and general grinding and mirror surface polish finishing. They are pen types, so they can handle detailed grinding and polishing work. Rotational speed can be adjusted and tip attachments changed to enable low-speed rotation for materials that cannot be worked on with high-speed rotation. Also, the tip part can be changed according to the diameter and shape of the tool used. Tip part materials include ceramic points and zirconia rotary burs. Ceramic points are suited for general polishing work as well as polishing of precious metal items and precision parts. The tip tool used must be selected according to the material it is used on.
