Dremel 408HP carbide sanding drum
408HP is a carbide-coated 1/2-inch 60-grit drum.

How to choose
Compare the integrated working surface when you want a coarse half-inch drum. The loose 408 sanding band is a different purchase for a reusable carrier.
Compatibility and limits
1/2-inch 60-grit carbide-coated drum · mounted 1/8-inch shaft
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 slide a 408 replacement band onto the 408HP?
The 408HP has an integrated abrasive face. The 408 refill belongs on the separate 407 carrier that Dremel lists for replaceable bands.
