This 8-piece set of Mini Circular Diamond Pads with hook-and-loop backs makes sanding and polishing a breeze. From coarse to ultra fine grit, each 25 mm pad attaches to your handheld rotary tool with the included 3 mm adapter shaft. It’s the perfect accessory to get the finished look on your small features. Not recommended for large surface areas.

  • 1500 grit (ultra fine) polishing (blue)
  • 3000 grit (ultra fine) polishing (orange)


  • Attaches to any rotary tool with included 3 mm adapter shaft
  • Interchangeable hook-and-loop pads perfect for variety of tasks 
  • Smooths high-fired clay, glaze, bisque, tile, stone or glass
  • Removes small imperfections
  • Smooth a foot or cup rim without damaging the glaze


  • Can be used wet or dry (doesn’t deteriorate in water)
  • Controls dust when used with water
  • Outlasts sandpaper
  • Less fatigue than sandpaper
  • Faster and easier than sanding with other types of abrasives  


  • Use all safety precautions
  • Keep out of the reach of children  

Note: The higher-grit pads have resin-based “dots,” which are designed for additional smoothing only after smoothing with lower-grit pads. The dots will show wear as the pads are used. This is normal and how they are designed to work. Trying to polish a piece without first smoothing with lower-grit diamond pads will cause the dots to wear much more rapidly.

One of the pads (orange, finest grit) came without grit. I emailed the company explaining this and have received no response. It’s been at least a week.


Fantastic! Smooths imperfections in glaze and unglazed stoneware

Updated review!

Wow, this company just blew me away! I submitted an honest review of this product which unfortunately became bent at 90* on my first attempt at using it. I was bummed out, but what can you do? Within minutes the company reached out, graciously acknowledged my misfortune with their product (use only in the forward setting in your Rotoflex!), and are now sending me a replacement shaft.
I am not used to companies standing by their products AND respecting their customers, and truly wanting their products to serve us well. I am now, hands down, a Diamondcore loyalist. 😂
Thank you, DC support team!

Good Quality

I use this to polish crystals. It is very effective on softer material. Hardness 6 or below on the Moh's scale.

Recently had some items come out of the bisque with bad scumming on the black clay. Didnt known what I was going to do, then I found and ordered the mini circular diamond pads for a dremel. I was shocked at how well and fast it removed the scum. Totally worth it! I would have been hand sanding for hours what they removed in minutes! Excellent product! Thank you!!

Thank you for your review, Christi! Glad to hear the Mini Circular Diamond Pad Set could remove that imperfection!
