Abstract

New cutting tools for hammer drills, characterized in that behind the head of the cutting part of the hammer, there are teeth that are intended to work in the opposite direction with respect to the drill teeth and that are located around the cutting bar, having provided that these teeth work during the exit of the hammer out of the hole drilled thus preventing the blockage at the bottom of the hole of the percussion apparatus, and can be forged or machined.
