An auxiliary device for a drill includes a base having a first side provided with a gathering portion, a fixing post mounted on a second side of the base and provided with a limit hole connected to the gathering portion, a water inlet port mounted on the second side of the base and provided with a water inlet hole connected to the gathering portion, and a water outlet port mounted on the second side of the base and provided with a water outlet hole connected to the gathering portion. Thus, the cooling water flows through the water inlet hole of the water inlet port into the gathering portion of the base to surround the drill bit so as to provide a cooling effect to the drill bit and the workpiece during the drilling process.
