Abstract
A drilling tool includes a cutting component and a clamping component. The cutting component comprises a cutting part and a connecting part. The clamping component comprises a clamping part matched with the cutting component. In a direction away from the cutting part along a rotation center axis, the connecting part has first and second outer circumferential surfaces, and the clamping part has first and second inner circumferential surfaces. The first inner circumferential surface is matched with the first outer circumferential surface to form a first radial clamping structure, and the second inner circumferential surface is matched with the second outer circumferential surface to form a second radial clamping structure. The first and second radial 10 clamping structures can independently achieving radial clamping of the cutting component by the clamping component, and an interference amount of the first radial clamping structure is greater than that of the second radial clamping structure.
