摘要： A pick tool comprising a strike tip and a pick tool body, the pick tool body including a non-rotating strike tip at a first end of the pick tool body. A shaft is provided at a second end of the pick tool body, the shaft being configured to pass through an opening in a surface of a pick tool holder, the shaft being configured in use to be non-rotationally attached to the pick tool holder. The shaft projects from a pick tool abutment surface such that, when the pick tool is attached to the pick tool holder, the abutment surface abuts the pick tool holder surface. The abutment surface has an aspect ratio between its length and width of between 1.5:1 and 3:1. The pick tool body comprises a leading edge and a trailing edge, the leading edge being, in use, the edge that first contacts a formation, the trailing edge having an angle of less than 18° between a main axis of the pick tool and an axis from the strike tip to the abutment surface at the trailing edge.
