Drill King - DTH Air Button Concave Bit
The CONCAVE bit is suited for most drilling conditions, as this design holds a very straight hole due to the tapered recess in the face of the bit. This recess or so-called “dish” causes a slight coring action, which helps keep the hole straight, while providing for excellent penetration and good air flushing of the hole.
