They are perfect for achieving mirror-like finishes on surfaces and eliminating even the smallest imperfections. Typical applications involve the final polishing of metals, glass, ceramics, and stone.

  5. Selecting the appropriate grit size depends on the specific task and the desired outcome. Here are some general guidelines:                   

  • Coarse Grits: Use coarse grits for rapid material removal, such as removing excess material, rough shaping, and grinding down welds or imperfections. The resulting surface will be relatively rough.                

  • Medium Grits: Medium grits strike a balance between material removal and surface finish. They are suitable for refining the shape and preparing the workpiece for finer finishing.

  • Fine Grits: Fine grits are used for achieving smoother surfaces and preparing the workpiece for polishing or final finishing. They are commonly used for achieving a consistent surface finish.

  • Very Fine Grits: Very fine grits are used for polishing and achieving high-quality, mirror-like finishes. They are essential in precision applications like jewelry making and fine metalwork.

It's important to match the grit size to the specific material and the stage of the operation. As a general rule, start with a coarser grit and progressively move to finer grits to achieve the desired surface finish while minimizing unnecessary material removal.
