A quality English made Tungsten Carbide Tipped masonry type Drill bit by Cintride. Has stamped on it 16mm 5/8 No. 26L Those measurements are correct, the following measurements are made by me using a builders tape so are only approx!! Measures approx 300mm long. The shank or skiny bit that goes in the drill chuck measures approx 35mm long x approx 10mm wide or diameter. People sometimes grind flats on the shank to hold tighter in the drill chuck. This is new and unused. The cardboard box in the picture is only a prop and is NOT included in the auction. I have a few of these, so if you need more than one, let me know and I will set up an auction for a couple or however many you need (till I run out of course) great if you need it. Be quick. Thanks. refN8124409
