Grinder Cookie Puck for Glass Grinding – Full Size & Mini - Designed by Coon Glass Studio

The Grinder Cookie Puck is a handheld, 3D-printed tool that helps you guide glass while grinding. Set the puck beside your glass on the grinder surface. Hold the raised grip and use the edge of the puck to gently push and steer the glass toward the grinder bit. This gives you a larger grip to work with and helps keep your fingertips farther from the bit.

Choose your size

• Full Size – 2¼″ disc width. Use the rounded edge or the notched area to hold and guide your glass, depending on the shape of the piece.

• Mini – 2″ disc width. Designed for smaller hands and for grinding small glass pieces.
