How to Change & Replace Rotary Cutting Blades
It's easy to change the blades on Omnigrid rotary cutters because the molded parts only fit together one way, making it impossible to reassemble incorrectly. Omnigrid rotary cutting blades are made of high quality tungsten-carbon steel; they're available in three sizes: 28mm, 45mm, and 60mm. It's recommended that you use Omnigrid rotary blades with Omnigrid rotary cutters, but they can be used with any standard rotary cutters.
