ABSTRACT:
The present invention relates to rotary tool bits driven by electric tools where torque forces are transmitted to the rotary tool bits by way of adapting means through the shank portions of other tool bits already in the electric tools. These adapting means comprise elongated members closely, axially aligned disposed about these rotary tool bits and have inside surfaces adapted to fit said shank portions. The elongated members are pressed against said shank portions by compressing means which might be sliding sleeves. The adapting means might comprise two, three or six such elongated members. Low friction sliding sleeves with interior rolling members for such rotary bits are also provided.
