Dremel 2615S407JA band-and-drum starter set
SC407 is a Dremel SpeedClic sanding-band and mandrel set.

How to choose
Choose it if you need the carrier with the bands for that working diameter. If you already have the holder, compare a refill band listed for the same drum.
Compatibility and limits
SpeedClic carrier with 13-mm bands · compare the fitted band and spare separately
Care
Choose the grit for the surface and the amount of material you need to remove. Dremel’s sanding guide separates shaping, smoothing and finishing stages.
Questions before buying
Can I buy loose half-inch bands if I already have the holder?
Check the carrier’s documented band sizes. The SC407 offer includes the carrier. The 408 listing is a separate coarse refill for a documented half-inch drum.
