Roller Cone Bit Classification Overview by 叶芊 is a document available to read on EtoBox.
This document discusses roller cone drill bits used in rotary drilling. It describes two main types of roller cone bits: milled-tooth bits and insert bits. Milled-tooth bits have steel teeth fabricated directly into the bit cones that cut formations by gouging or scraping as the bit rotates. Insert bits use tungsten carbide cutting inserts attached to the cones that shear or crush formations. The document discusses various design aspects that impact the cutting action of roller cone bits like geometry, cone
