The present invention relates to a machining tool (1) for machining extremely hard materials, and to a method for manufacturing same. Such a machining tool comprises a cemented carbide main body which is rotationally symmetrical with respect to a rotational axis (z) and which has a front end (20) and a shank (10) designed to be clamped into a tool holder of a machine tool. The front end is formed as a rotationally symmetrical tool tip (20). This tool tip (20) is thus formed integrally with the shank (20) of the cemented carbide main body. At least one hard material layer (24), such as a diamond layer, is applied over the entire surface of the tool tip (20). A plurality of flutes (25) having cutting edges (30) extend within the hard material layer (24), said flutes being introduced into the hard material layer (24) exclusively by means of laser machining.

This application provides an ultra-hard deep hole honing cutter, including a honing cutter body, which includes a connecting part, a cutter body, and a cutting part. The outer surface of the cutting part has a first spiral chip removal groove and a second spiral chip removal groove. The outer surface of the cutting part has a plurality of first liquid inlet holes and a plurality of second liquid inlet holes. A liquid guiding cavity is formed inside the cutting part. When coolant is sprayed onto the cutting part of the honing cutter body through an external nozzle, the coolant can first contact the outer surface of the cutting part. Through the cooperation of the plurality of first liquid inlet holes and the plurality of second liquid inlet holes, the coolant can enter the liquid guiding cavity and contact the inner wall of the liquid guiding cavity. Through the cooperation of the inside and outside, the cooling rate of the cutting part can be improved, and the cooling effect can be further enhanced. The first spiral chip removal groove and the second spiral chip removal groove form a double-threaded chip removal channel on the cutting part, which can improve the chip removal effect of the cutting part itself.
