I have a set of Cleveland piloted countersinks and a set of counterbores. I use these for SHCS and socket head, flat head screws.
I can find new counterbores but cannot find piloted 82 degree countersinks anywhere. These have a fixed pilot in the diameter of the appropriate clearance hole and a body diameter that matches the OD of the flat socket head fastener.
I'm guessing they quit making these things. Here is an example of what I have. Anyone seen a source for these things..they aren't run-of-the-mill counterbores, they're specific to socket head fasteners dimensions.
