Drilling bit selection knowledge Solid rock 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. Gneiss is often fine grained and has high quartz content, o the bit wear is high and material can be hard to drill.

How does a drilling tool work?

When drilling in rock, the sharp end of the drilling tool, or bit, is driven into the rock by means of a dynamic (percussion, in which the bit rotates slightly in response to each stroke) or static force (rotation). The material excavated by the bit is stripped out of the hole by shearing as the bit advances.
