Seems to be really hard to find a good countersink to fit my 1/4" Hex Craftsman quick connector. I found a cheap one locally but it just went through the stuff instead of a countersink to cut. This countersink is well made - I can see the grooves on the countersink are actually set for cutting stuff as opposed to the crappy one. I had before. The packaging says it's for countersinking wood, plastic and metal is designed.
