<p>A chuck and an article are configured such that the article is releasably secured in the chuck. One of the chuck and article is provided with a crest and the other with a trough. When the article is secured to the chuck, the crest enters the trough so as help prevent slippage of one with respect to the other. The chuck may include a receiver having a tapered bore, a collet having a complementarily tapered outer surface, and a nut configured to be threadingly secured to a forward end of the receiver; the article may be a shank, such as a tool shank. An inner surface of the collet may be provided with a crest which is configured to fit into a trough formed on the shank. In a secured position, the shank is accommodated in the bore of the collect with the crest of the collet at least partially occupying the trough of the shank, thereby preventing movement of the shank relative to the collet, which itself is accommodated in the bore of the receiver.</p> |
