ABSTRACT:
The tool assembly is intended for woodworking machines having an integral spindle drive with electric motor and rotary tool holder combined in a one-piece unit; use is made of a tubular sleeve to accommodate the spindle drive, which is mounted coaxially at one end with the tool and holder projecting, and supported by a set of radial webs alternated with a similar number of openings and bridging a gap created between the motor and the sleeve, given that the transverse dimensions of the spindle unit are less than the bore of the sleeve. The sleeve connects at the top end with the duct of an extractor system and is carried slidably in relative supports, capable of controlled traversing movement along its own longitudinal axis.
