Pottery Trimming Spinners (Sold Individually)


Our handy Pottery Trimming Spinner helps stabilize your piece and disperses downward pressure to keep thin-walled pieces from collapsing.

The colored lines on the spinner also make convenient division hash marks. It works perfectly in conjunction with our sticky bats and sticky pads too!   


  • No moving parts
  • Foam rubber backing grips the spinner to a piece being trimmed on a wheel
  • Use one hand for trimming, then place a finger of your other hand in the spinner’s concave center, helping to stabilize the piece
  • String or fishing line looped through the center hole can extend to mark lines on a piece instead of using a laser
  • Trimming Spinner is 48 mm (~2”) in diameter with a 6 mm (1/4") hole in the center. Hashmarks provide five options for equidistant divisions. 
  • Trimming Spinner XS is 31 mm (~1.25”) in diameter with a 6 mm (1/4") hole in the center. Hashmarks provide seven options for equidistant division.
  • Trimming Spinner XL is 75 mm (~3”) in diameter with a 6 mm (1/4") hole in the center. Hashmarks provide guides every 10 degrees around, with 10 options for equidistant dividers.


  • Makes trimming quicker and easier
  • Colored division lines provide quick reference marking
  • Use in conjunction with our sticky bats and sticky pads


  • Provides a wider area to disperse downward pressure
  • Helps keep thin-walled pieces from collapsing
  • Allows trimming hand to be stabilized on the other hand
  • A rubber grip works better than a bottle cap or credit card 
  • Made in the USA


    • Keep gentle downward pressure while the piece is turning
    • Use all safety precautions
    • Keep out of the reach of children

    Must Have Mini Helper

    Quick, quality, and versitle. Measurements can be made easily, and accurately. Really helps keep down pressure during trimming.

    Neat little tool

    Works really well with the sticky bats! If you're already getting a sticky bat, definitely pick one of these up too. This trimming spinner makes "side" trimming easier, and I have fewer pots fly off the wheel when trimming.

    Helpful studio buddy

    Awesome to avoid your fingers catching on clay while trimming, i actually find it helps me center the clay faster, and super convenient measurement markers for lining up handle placements, decoration, etc!
