A quill clamp is provided for releasably gripping a spindle of machine tools such as milling machines, drilling machines, jig bores, horizontal boring mills and N.C. mills. In addition, the dial test indicator holder may be connected directly without a quill clamp to height gauges, collet holders and magnetic bases. The main body of the dial test indicator holder of the invention is formed of a plurality of main body links each comprised of parallel, separated body link elements. The main body links are connected by intermediate links utilizing a plurality of releasable fastener assemblies. Main body links may be removed and added by manually releasing and disengaging the fastener assemblies to acheive a desired overall length.
