This adapter holds powder funnels for Dillon presses so they can be spun up in an electric drill or drill press while cleaning brass residue off the tip. Spinning the powder funnel greatly speeds up the cleaning process. Just hold some steel wool against the tip.

All powder funnels will eventually need cleaning. But when loading new, ultrasonically cleaned or stainless steel pin cleaned brass, the need for frequent cleaning is critical due to powder funnel sticking and the resulting brass smearing. The following quote is from Dillon Precision Technical Support.

"It is common for new, once-fired and sonicly-cleaned brass to stick to the funnel. Until the brass has been internally smoothed from firing, plus the carbon-coating lubricates, preventing the sticking. If loading new brass in particular, use a Scotch-Brite pad or steel wool to wipe off the funnel every 25-35 cases."
