Abstract
A tool is described comprising a first part (14) adapted to be received by a part of a power tool, in use, and a second part (20) adapted to cooperate, in use, with a core drill bit (12), the first and second parts (14, 20) being releasably couplable to one another by a releasable coupling including a coupling pin (30) that, in use, extends within aligned passages (26, 28) formed in the first and second parts (14, 20), the coupling pin (30) including a resilient retainer clip section (32) that resiliently extends around at least part of, and engages, the first or second part (14, 20) to retain the coupling pin (30) in position. An arrangement in which a support member is carried by the second part is also described.

A tool comprising a first part adapted to be received by a part of a power tool, in use, and a second part adapted to cooperate, in use, with a core drill bit, the first and second parts being releasably couplable to one another by a releasable coupling including a coupling pin that, in use, extends within aligned passages formed in the first and second parts, the coupling pin including a resilient retainer clip section that resiliently extends around at least part of, and engages, the first or second part to retain the coupling pin in position.
The tool adapted to be received by a part of a power drill, in use, and to cooperate, in use, with a core drill bit to be provided, the tool containing an axial though passage extending over the complete length thereof.
An alignment tool comprising a threaded support stub of relatively large axial length and with which a core bit is in threaded engagement, in use, and a support member secured to and in threaded engagement within the support stub, the support member including a section located within the core bit, in use, and a section projecting from the core bit, in use, the support member and the core bit, in use, being coaxial with one another.
