Circle Cutter is a hand tool with a bar the scoring head can slide on which is held in place with a set screw. The bar is connected to a central hub that has a suction device or anti-skid surface so it can spin around but this limits the minimum size to around 0.5in(12.7mm). Circle cutters should not be confused with a Lens Cutter which does the same thing but in a different way.
Circle cutters that use suction based hubs don't work well on irregular surface glass.
Similar Tools
Lens Cutter which allows for smaller circles than a Circle Cutter to be cut.
Uses
Scoring circles or arcs of various sizes.
How to Use
- Measure the Diameter or Radius of the circle you wish.
- Set the Circle Cutter to the Radius or half of the Diameter. Note: If your tool has a ruler on it, verify it is correct before using it!
- Position the hub in the center of the glass you want to score on the smoothest flattest side.
- Hold down the tool or push the suction lever down.
- Grab the cutting head and apply force while rotating to score.
- Add some Relief Cuts to free the part.
- Run the score lines to remove the waste glass.
