The present invention'relates toles, rasps or like tools.
The files known up to now are made of` now usually cut and to harden it by a spe- 'cial hardening process whereupon the sov formed file may bev mounted on any suitable body,.for instance on to the rim of a rotary j disk, to a bar of wood or of metal and so on. The iron piece of which the file is made may invention ina section,
be fiat, or'eurved lengthwise or crosswise, it. maybe a tube of cireularor any other crosssection.
The invention further consists of details of construction, which together with the fea-Mv tures iirst mentioned, will be better understood by reference to the drawing.
In the drawing v Fig. l shows a rotary tool according to the vFig. 2 isla face view thereof, y
Fig. 3 shows as another tool acco'rdingrto this invention altubular ile in longitudinal section. l
The tool vaccording .to Figs. l and 2 come prises two circular disks 2, inounted 0.11 a shaft l and firmly held thereon by means of a nut 4f screw-'ed on to a screw threaded per` tion 8 ofthe shaft 1 which nut 4 presses the disks on to a collar of shaft l.. The rims of the two disks 2,v 3 are bevelled in opposite directions.
