Abstract
A surface-coated cutting tool includes a coating layer () formed on a substrate (), wherein assuming that the average thickness of the coating layer () on a first surface () and a second surface () of the substrate () is A, a difference between the maximum and minimum thicknesses of the coating layer () is 0.04×A or less. Also, a surface-coated cutting tool includes a coating layer () formed on a substrate (), wherein assuming that the average thickness of the coating layer () on a first surface () of the substrate () is B, and the average thickness of the coating layer () on a second surface () of the substrate () is B, a value obtained by dividing an absolute difference value between Band Bby a larger value of Band Bis 0.04 or less.
