The HS310-5B attaches to standard drills to shave and finish the heads on the RV6607-5 series Bulb-tites (5/32" diameter series of Shaveable Aluminum Bulb-tite rivets. Installed rivets are first trimmed of the excess mandrel protruding above the rivet head using side cuts. Next, the HS310 is mounted in a standard 3/8" drill and positioned over the rivet head. Actuating the shaver finishes the rivet head to provide the appearance of a brazier head solid rivet. This tool is for aluminum shaveable rivets. If you use if for anything else you will likely damage it. Make sure the shaving bit is spinning at high speed before touches the rivet. If out of stock it could take 3-4 weeks to get one in.
