Abstract
The present invention relates to an improved roller cone core bit comprising a plurality of cone cutters facing inboard and a single cone cutter facing outboard. The single outboard facing cone cutter provides additional cutting elements for cutting a core. The single outboard facing cone cutter also creates an unbalanced loading condition on the core bit causing the bit to drill smoother than conventional reversed cone core bits.
