Abstract

A holder according to one embodiment is provided with a body section extending along a rotation axis from a first end section toward a second end section. The body section is provided with: a first portion located on the side of the body section which faces the first end section and having a pocket in which a cutting insert is mounted; a second portion located closer to the second end section thanthe first portion and having a cavity therein; and a third portion located closer to the second end section than the second portion.

Description

Technical field [0001] The present invention relates to a tool holder, a cutting tool, and a method of manufacturing a cutting product using the tool holder, cutting tool, and cutting tool used in cutting. Background technique [0002] As a cutting tool used for cutting a workpiece such as a metal, a cutting tool described in International Publication No. 2010 / 092807 (Patent Document 1) is known. The cutting tool described in Patent Document 1 is a tool used in a rotary cutting process such as a milling process, and is called an end mill. The cutting tool used in the rotary cutting process includes a tool body (tool holder) that rotates around a rotation axis, and a cutting insert attached to an insert mount (groove) of the tool holder. The cutting tool described in Patent Document 1 further includes an upper wall portion that protrudes with respect to the groove. The upper wall portion prevents the tool holder from being flexed, thereby improving rigidity. [0003] In the case w...
