Basic Rock Information
Gneiss is often fine grained and has high quartz content, the bit wear is high and material can be hard to drill.
Limestone is normally easy to drill; penetration is high and the bit wear is low. Sandstone is very often also easy to drill, but bits can wear out rapidly because of the high quartz content.
Strongly layered rock can be difficult to drill; small drilling angle against the layers causes the biggest problems. Correct bit is essential for good drilling results.
Limestone is normally easy to drill and causes only a small amount of bit wear. When the rock looks like this, bad fragmentation causes jamming of the rods. Hole deviation can also be a problem. Retrac type of bits are highly recommended.
