Diamond Pottery Files

Diamond files for clay

If you’re looking for a diamond file for pottery, you’re in the right place. You can use them to file and fix localized imperfections, or to polish and shape specific surface areas. Thanks to their sintered diamond grit, they can handle hard glazes and all kinds of materials such as stoneware, porcelain, and earthenware.

Model files

Available in various shapes and sizes to suit every detail of your work. From fine edges for precision finishing to wider profiles for larger surfaces, find the perfect file for your pottery, ceramics, or jewelry projects.

Jewelry files

Also suitable as jewelry files—ideal for removing burrs, cleaning up glaze drips, fine-tuning settings, and finishing edges on small pieces (earrings, pendants, beads…). They’re not just for ceramic jewelry: their micro-grit diamond abrasive works on all kinds of metals, too. So although we designed them for professional ceramicists, these are true do-it-all files you can use not only on clay, but on virtually any material you need.

Needle files 

Miniature files: The smallest files have a cutting edge width of 2 mm and an edge thickness of 1 mm. If you need something even smaller, we can make it custom for you.


Diamond Files for Ceramics – FAQ

1) What are diamond files used for in ceramics?
They are used to correct localized defects, remove burrs, glaze drips, refine edges, and adjust specific areas of a piece. They are precision tools designed for working on very specific points.

2) What is the difference between a diamond file and diamond sandpaper?
A diamond file allows for more precise and localized work, making it ideal for details, grooves, handles, or edges. Diamond sandpaper, on the other hand, is designed to smooth larger surfaces evenly. For this reason, both tools complement each other rather than replacing one another.

3) Can diamond files be used on hard glazes?
Yes. Thanks to their sintered diamond grit, these files can be used without difficulty on hard glazes, vitrified burrs, or residues from kiln shelf protectors.

4) Are they only suitable for ceramics, or also for other materials?
Although they are designed for ceramics, stoneware, and porcelain, diamond files also work very well on metals. This is why they are commonly used in ceramic jewelry and other precision work on different materials.

5) At what stage of the process are they used: before or after firing?
They are mainly used after firing, both on bisque ware and after glaze firing.

6) Is it better to use them dry or with water?
They can be used in both ways. Working wet reduces dust and improves the feeling of control, while dry use allows for quick and direct corrections in very specific areas.

7) Do diamond files require maintenance or sharpening?
They do not require sharpening. It is enough to clean them after use to prevent the buildup of dust or glaze and to store them dry. Sintered diamond maintains its cutting ability for a long time.
