Equipped with a thin-walled crown segment with a height of 12 mm, which is attached to the drill pipe by a Zig-Zag laser weld.
The deep vertical slots in the segment ensure optimal cooling and continuous discharge of the slurry.
Laser welded: 100% guarantee against weld breakage.
The EVO/SPEED bond has been carefully composed of a mix of metal powders and diamond grains that guarantee a high production speed in all types of concrete, both when drilling "by hand" and in combination with a drill stand.
The drilling efficiency of the EVO/SPEED is average.
