Review on Melin Tool Rounding Uncoated Non Center Cutting Tools by John Ghattamaraju

Good quality carbide burr that is EXACTLY as described (assuming you can read). Shank Size if that is the size of the part of the cutter that is held in your spindle. The cut diameter is twice the radius (the amount of cut created at the edge). So a 1/8" diameter cut with a 1/4" shank would have a 0.25" diameter drill bit with a 0.0625" (1/16") shank. ) radius corner cut profile.
