Problems solved by technology

[0007] However, in the methods of brazing the cutting edge portion of the tool body as in Patent Documents 2 and 3, when the diameter of the tool body is reduced for small-diameter hole machining, the brazing area of ​​the cutting edge portion decreases and the brazing strength decreases. As a result, the cutting edge may peel off during cutting

Abstract

The invention provides a bore machining cutter head and a bore machining cutting tool, which are cheap to manufacture and high in brazing strength. The bore machining cutting tool (T) is formed by installing a bore machining cutter head (1) onto a cutter rod (100). The bore machining cutter head (1) comprises a rod-shaped tool body (2); and a cutter head (4) of a cutting edge (3) protruded to the side (17) out of the rod-shaped tool body (2) with the lower surface (16) thereof arranged on the tool body (2). The lower surface (16) and the upper surface (18) of the cutter head (4) of the cutting edge (3) are partially clamped by the tool body (2). The upper surface (18) of the cutter head (4) of the cutting edge (3) is partially brazed to the tool body (2).

Description

technical field [0001] The present invention relates to an inner diameter machining bit and a cutting tool for inner diameter machining suitable for inner surface machining of a small-diameter hole provided with the inner diameter machining bit. Background technique [0002] As a cutting tool for machining an inner diameter of a hole, for example, as in Patent Document 1, a shape in which a cutting edge is formed on a side of a tip of a rod-shaped body is widely used. Cutting tools of the above-mentioned shape tend to have a smaller cutting edge in order to cope with small-diameter machining, and the other parts are hardly damaged, and the life of the cutting edge is often reached. Therefore, a more effective method of use is desired. [0003] On the other hand, Patent Documents 2 and 3 disclose a cutting tool for inner diameter machining. A cutting edge portion having a single crystal diamond blade is brazed to the front end of the tool body (tool head, shank). The cutting...
