Review on Topec Diamond Drilling Granite Concrete by Chad Mills

Screws on hand grinder. Make sure you have a helper to pour water on the racket while using it, or you will burn it. A small garden watering can with a 1/4 inch spout works great. Keep a constant flow of water on it. You must use one size larger than the anchor. Inward, inward, pulling the anchor with pliers every few minutes. Chisel and anchor get hot - wear gloves. I pulled nine dowels out of the basement wall. Fill the hole with quick-set concrete using a popsicle stick or similar tool. A small bucket at a hardware store. Don't make an air pocket.
