ABSTRACT:
A spirit leveling attachment for a power tool which is universally adjustable relative to the tool so as to enable the tool to be located in anyone of a number of selected positions of angularity and maintained in such position by visual reference to the spirit level. A magnetized support member having a partly spherical recess is mounted on the tool. The spirit level is formed with a partly spherical body member which is accommodated in the recess of the magnetized support member, enabling the body member to be magnetically retained in the recess in selected positions of adjustment relative to the support member.
