Especially when dealing with items such as polished beads that require extremely high integrity, how to obtain material samples without damaging their appearance becomes a highly challenging task. Traditional methods often choose to minimally invasive sampling inside the bead hole, however, this process lacks efficient special tools and usually relies on manual operation - one hand holds the bead, and the other hand holds a miniature drill to sample. This approach has many limitations:
