<p>An adjustment member (26) is mountable on the housing nose (24), being relatively rotatable w.r.t. the nose and the locator (28). This sets the distance between the nose and the locator. A link permits axial movement of the locator relative to the nose when the depth adjuster is mounted on the tool but prevents relative rotation between them. - A seal (84) associated with the adjuster and the locator prevents the entry of foreign particles into the housing. The exterior of the locator and the interior of the adjuster are pref. threaded together.</p> |
