Abstract

PURPOSE:To eliminate a suspicious trouble of coming-off and breakage of screws, by holding tool blocks to tool supporting bodies and laterally mounting the tool supporting bodies with the screws from a drill head portion into the tool supporting body. CONSTITUTION:In the point end part of a cylindrical drill head 1, a plurality of hollowed places 2 for housing a spporting body are provided, and square pillar shaped tool supporting bodies 3 are fitted into the hollowed places 2. Slotted grooves 4 are provided in end parts of the tool supporting bodies 3. Tool blocks 5 are fitted and fixedly tightened into the slotted grooves 4 by tightening devices 6, 13. The above described screw, being of construction laterally mounted from a portion of the drill head into the tool supporting body, can eliminate a suspicious trouble of coming-off and breakage with easy mounting work.
