Review on Mgtgbao 5/16”Blue Diamond Finger Bit, 8Mm Diamond Finger Milling Bits For Enlarging And Shaping Or Round Bevel Existing Holes In Porcelain Hard Ceramic Stone Granite Marble Tile by Robert Pierce

You will need an adapter. When I ordered it on revain the only picture in the ad showed the drill with a1/2” shank. What I received had a 5/8-11 female. I don't know if this has happened to other people or if I'm a only a one off. The tool itself is average, nothing special. The only tools I have that take a 5/8-11 are angle grinders so these must be for cleaning up edges and stuff. So my experience from this company was a bad one so I have to take stars from it. Original ad said a drill with a 1/2” shank which would have fit my milling machine. Now I have to adapted it .
