I've used Aluminum Oxide (from HF) on heavy stuff. Be careful though, it can be pretty rough on certain items. Also a 50/50 mix of Glass Bead & Aluminum Oxide to calm down the cutting power of the Aluminum Oxide. Have also tried Red Garnet for some of the smaller items. Right now I've got regular playground sand from Home Depot in my cabinet and it works pretty good.
I also have a TP Tools 960 cabinet.
