| description | The efficient composite drill is applied to the field of tool machining and comprises a tool handle, a tool body is arranged at one end of the tool handle, a drill tip is arranged at the end, away from the tool handle, of the tool body, two main cutting edges are arranged on the drill tip, two chip grooves are formed in the tool body along the peripheral wall, and the two chip grooves spirally extend to the tool handle from the tool body along the central axis of the tool body. The two chip grooves are respectively communicated with the main cutting edge, and a circumferential edge is formed between the two chip grooves. The machining method has the technical effects that cuttings generated in the machining process can be discharged along the chip grooves, accumulation of the cuttings is effectively reduced, the possibility that the cuttings interfere with machining of the hole wall of a workpiece is reduced, the shapes of the chip grooves are optimized through the circumferential blade gaps and the main cutt |
