Hayden Bits
Drill bits

HAYDEN uses a number reference guide (Hayden 1–16), corresponding to the matrix hardness for ease of selection. (HAYDEN 1 being the hardest matrix and HAYDEN 16 being
the softest.) The higher the number, the harder, finer grained, more competent and nonabrasive the rock type the bit is capable of drilling. Conversely, the lower the number
selected the more broken, fractured coarser grained and abrasive a formation the bit is capable of drilling.

HAYDEN manufactures slight variances of the standard matrices to fine-tune the bits’ performance considering the drill rig capabilities and formations being encountered.
