Portable power drill accessory - comprises round rotary dust collector vessel with sealing lip fitting over drill bit

摘要

The portable power drill accessory comprises a round rotary collector vessel with a central opening for the high-speed drill bit, opposite which is another opening for the produced dust, swarf, etc. of smaller dia. than the max. internal dia. of the vessel. At the drill bit opening (3) the vessel (1) has a sealing lip (4), by which it is slid over the bit (16). This lip can be inserted in the opening. The design reduces the escape of dust between the vessel and the wall etc. being drilled and also protects the drill chuck from damage caused by penetration of this dust. PS.
