What can you do with it? It is designed for cutting and separating metal, including hardened steel. Ideal for cutting, notching, and trimming all types of metal. Cutting discs make it easier to separate bolts and screws or to notch rusty or damaged bolts and screws for removal with a screwdriver. Fiberglass reinforced for a longer lifespan. The SC409 series cutting discs are only 0.75 mm thick, allowing for even thinner cuts.

How does it work? For use with the SC402 mandrel. Dremel's exclusive Easy SpeedClic (SC) mechanism ensures quick, easy, and tool-free disc changes: Pull – Twist – Click. Six times faster accessory changes than with a standard mandrel (EZ SpeedClic mandrel SC402 sold separately). Cutting discs can only be used on the edge. For this accessory, we recommend a (two-handed) golf grip and using the angle attachment when cutting in hard-to-reach places. To optimize the lifespan of the disc, apply only light pressure and adhere to the speed limitations.

For use on the following materials: This cutting disc can be used on various types of metals such as aluminum, copper, cast iron, or even hardened steel. Recommended speed: Aluminum 35,000, Brass 35,000, Copper 35,000, Steel 35,000.
