摘要:
Earth-boring tools include a body and one or more replaceable cutting structures attached to the body at a face region of the body. Each replaceable cutting structure includes an attachment member and a cutting portion located to engage an earth formation. Methods of forming an earth-boring tool involve attaching one or more cutting elements to a replaceable cutting structure; positioning the replaceable cutting structure proximate a region of a body of an earth-boring tool that is susceptible to at least one of localized wear and localized impact damage; and attaching the replaceable cutting structure to the body. Methods of repairing an earth-boring tool involve bringing a replaceable cutting structure proximate at least one portion of a body of an earth-boring tool exhibiting at least one of localized wear and localized impact damage; and attaching the replaceable cutting structure to the earth-boring tool at the at least one portion.
