Abstract

A modular kerfing rock drilling bit (10) is presented. Drill bit (10) comprises a bit body (12) having a connection (14) for attachment to a drill string member. A base portion (16) below the connection (14) has an outer portion (18) and a bottom (20). Slots (22) are formed in the base portion (16). A cutter assembly (100) comprises a leg (110) insertable into the slot (22) of the bit body (16). A journal (126) extends angularly downward and inward from the leg (110) for bearing support of a cone (180) rotatably mounted on the journal (126). A plurality of cutters (182) extend outward from the surface of the cone (180). A kerfing segment (140) extends downward from the leg (110) beyond the cone (180). A plurality of kerf cutters (142) are attached to the bottom of the kerfing segment (140).
