A record handling tool employs a retractable spindle for engaging and gripping the spindle hole of a recording disc. The retractable spindle is positioned coincident with the spindle hold by contact of two spaced-apart grooves on guide arms on a record handling tool with the circular rim of the recording disc. The retractable spindle is left in its retracted position while a support arm of the tool is inserted into a dust jacket between the dust jacket and the recording disc. When contact is made between the guide arms and the edge of the recording disc, thus positioning the retractable spindle coincident with the spindle hole of the recording disc, the retractable spindle is extended from the support arm thus passing through and gripping the recording disc by its spindle hole. The recording disc remains clamped in a three point grip including two spaced-apart points of contact on the circular edge of the recording disc as well as the single point of contact at the spindle hole.
