Zusammenfassung:To provide a tool holder and a machine tool capable of changing a cutting byte used for processing without needing indexing.SOLUTION: A tool holder 71 mounted to a tool main spindle unit comprises tool holding parts 75a and 75b that hold a plurality of cutting bytes 73a-73d for cutting a workpiece. Tips 73a1-73d1 of the cutting bytes 73a-73d held by the tool holding parts 75a and 75b are positioned away from each other in a first direction N1 along a center axis I of the tool holder 71 and second and third directions N2 and N3 intersecting the first direction N1, and opposed to the workpiece held by a first main spindle or a second main spindle.SELECTED DRAWING: Figure 5 【課題】割り出し不要で、加工に使用する切削バイトを変更することができる工具ホルダ及び工作機械を提供する。【解決手段】工具主軸ユニットに装着される工具ホルダ７１は、ワークを切削する複数の切削バイト７３ａ～７３ｄを保持する工具保持部７５ａ，７５ｂを備える。工具保持部７５ａ，７５ｂにより保持された複数の切削バイト７３ａ～７３ｄそれぞれの刃先７３ａ１～７３ｄ１は、互いに工具ホルダ７１の中心軸Ｉに沿う第１方向Ｎ１、第１方向Ｎ１に交わる第２方向Ｎ２及び第３方向Ｎ３に離れて位置するとともに、第１主軸又は第２主軸により保持されたワークに対向して位置する。【選択図】図５
