Rated 4 out of 5 by Different but needed! How do you review something as simple as a countersink? But this is not any countersink, with a diameter of some 20mm (3/4 inch of us oldies) it's not your everyday countersink! But it arrived as stated, the next day as always and proved a nice clean cut for the large diameter set screws being used! Before this using this size of screw meant that either the screw stood proud or a rough countersink sort of hole was drilled that looked poor - now the works look professional - Screwfix to the rescue again, beats "International Rescue" any day!! 2 Aug 2014
