Review on 🔪 Enhance Precision with Fuller C8M Number Complete Countersink by Kyle Mason

Required conical and countersunk holes in wood to be joined for storm blinds. Matching the pan heads to the stainless steel pan head screws I used was easy. I've never had a countersink that didn't need cleaning every few holes. (Wood dust is clogging the sink area and causing an incorrect depth.) I guess someone will eventually invent a device that cleans itself, but so far it's the best I've used.
