[0002] A drill is a mechanical device used to drill holes in materials. The drill uses a motor to drive the drill bit to rotate at high speed, and uses the cutting edge of the drill bit to cut the material to form a hole. A grinder is a mechanical device used to grind, cut or polish materials. The grinder uses a motor to drive the grinding head to rotate at high speed, and uses the abrasive of the grinding head to cut, grind or polish the surface of the material.

[0003] When processing a workpiece, it is usually necessary to use a drill to drill a hole and then grind it, which requires the use of two power devices or frequent replacement of the drill bit and the grinder.

During this process, the elastically supported retaining ring (24) limits the latch (34) to prevent the latch (34) from falling off. The latch (34) is fixed, so that the drill bit (4) and the grinding wheel (5) can be easily replaced, and the drill bit (4) and the grinding wheel (5) are adjusted according to the processing specifications of the workpiece; S2: During use, the dual-axis motor (12) operates to drive the output shaft 1 (2) and the output shaft 2 (3) to rotate, and the output shaft 1 (2) and the output shaft 2 (3) respectively drive the drill bit (4) and the grinding wheel (5) to rotate. The housing (1) can be moved by the ball bearing (9), or the workpiece can be moved to correspond to the processing tool drill bit (4) and the grinding wheel (5), so as to achieve the drilling and grinding of the workpiece. During the processing, the same motor is used as the driving source, and there is no need to replace the equipment. Only the fixed position of the workpiece needs to be adjusted; S3: When the output shaft 1 (2) and the output shaft 2 (3) rotate, the driving wheel (17) and the driven wheel (21) are linked by the belt (19). When the output shaft 1 (2) and the output shaft 2 (3) rotate, the driving wheel (17) drives the pump shaft (20) to rotate, thereby causing the impeller (22) to generate a suction force inside the pump casing (13). The suction force is guided by the connecting pipe (14), the collecting box (15), the suction pipe (7) and the suction cover (10) to suck the processing parts of the drill bit (4) and the grinding wheel (5), so that the generated metal debris is effectively collected, thereby achieving a dust removal effect.
