Publication number: 20230366283Abstract: A cutting tool can be used to cut through a tubing string in a wellbore. Metal cuttings are formed during the cutting process. The cutting tool can include a cutting insert with a blade that is rotated around a longitudinal axis of the tool. A nose can include a spiral cutout adjacent to the blade. The spiral cutout can force the metal cuttings down past the outside of the nose and down into the tubing string. The nose can also include a guide on the outside underneath the blade. The guide can also provide a pathway for the metal cuttings to fall past the outside of the nose and down into the tubing string. The spiral cutout and the optional guide can be used to prevent metal cuttings from lodging within the cutting tool and preventing the tool from rotating and cutting.Type: ApplicationFiled: May 12, 2022Publication date: November 16, 2023Applicant: Halliburton Energy Services, Inc.Inventor: Simon Whye Kwong WAI
