Abstract
Collector for manual drills, characterized essentially by the fact that it consists of a tubular body in which the chuck of the drill is housed rotatably, the body of which has a base provided with a nozzle through which the bit is through, at the base of which it engages an elastic tubular body in the manner of a bellows at one end, while at the opposite end receives a closure bushing having a hole through which passes the drill, whose penetration into the wall is allowed by said elastic body as a bellows when supporting the same in the former, in whose elastic body the drilling dust is collected, which does not reach the chuck because the nozzle at the base of the tubular body surrounding it prevents it.
