* The power from the hammer drill is effectively transmitted to the tip of the drill bit by means of the 12 grooves cut into the shank.
* Thanks to the 12 groove arrangement, the load on each groove is less and thus the shank has outstanding service life.
* For bit installation and removal you need only twist the tool retainer 180 degrees. There is no need to handle a hot bit after operation when changing bits.
* Professional quality for fast, efficient hammer drilling in hard materials like concrete, granite, cement, brick and other types of masonry.
* Inch sizes are available. (Supplied Size for 1/2" ~ 1-1/2").
