Handheld quantitative grinder

Product use: The height of the sample being ground and polished in the grinder can be manually adjusted to achieve quantitative grinding and polishing. The sample end is made of special wear-resistant material.

Usage: Hot melt adhesive can be used to stick the sample inside the grinder, adjust the height to be ground off, and then lock the middle nut. After adjusting the height, fix the sample with three screws around the grinder (customized). Then, the hand is used for grinding and polishing until it reaches the black wear-resistant material, completing the quantitative grinding and polishing.

Attention: Please be sure to wear protective gloves when using this product.
