PICK TOOL AND METHOD OF USING SAME
A pick tool for pavement degradation or mining, comprising an insert and a holder, the insert comprising a super-hard strike tip joined to a proximate end of an insertion shaft. The insertion shaft is secured by an interference fit within a bore provided in the holder, the insertion shaft having a longitudinal axis and a distal end of the insertion shaft positioned at an insertion depth within the bore. A wear limit marker is provided on an external surface of the holder and positioned to correspond to an axial distance along the insertion shaft from the distal end, the distance being at least 20 percent and at most 35 percent of the insertion depth.
