Embodiment Construction

[0029] exist figure 1 shows a screw-in tool 1 with a tool head 2 and a tool shank 3 . A cutting edge (not shown) is arranged on the tool head 2 for cutting a workpiece. The tool shank 3 has an external thread 4 , a first support region 5 arranged between the tool head 2 and the external thread 4 and a second support region arranged between the free end 6 of the tool shank 3 and the external thread 4 7. The free end 6 is formed by the end face of the tool shank 3 .

[0030] The first support region 7 has support elements 8 spaced apart from one another in the circumferential direction and projecting radially outward. refer to figure 2 The configuration of the support member 8 is described in detail.

[0031] exist figure 2 shown in detail in figure 1 The second support area 7 of the screw-in tool 1. As can be seen in the figure, the support elements 8 are designed as webs extending in the axial direction of the screw-in tool 1 and spaced evenly from one another. In t...

Abstract

The invention relates to a screwing tool (1) comprising a tool head (2) and a tool shaft (3); the tool shaft (3) has an external thread (4), a first support section (5) between the tool head (2) and the external thread (4), and a second support section (7) between the external thread (4) and a free end (6) of the tool shaft (3). According to the invention, the second support section (7) includes supporting elements (8) which project radially outward and are located at a distance from one another in the circumferential direction.

Description

technical field [0001] The invention relates to a screw-in tool according to the preamble of claim 1 , a tool holder / tool ​​holder and a tool arrangement. Background technique [0002] A screw-in tool with tool holder is known from document DE 10 2012 100 976 A1. The screw-in tool includes a tool head and a tool shank. A cutting edge is arranged on the tool head for cutting. The tool shank has an external thread for connecting with a tool holder. On the tool shank, a first support region is also formed between the tool head and the external thread, and a second support region is also formed adjacent to the free end of the tool shank. For this purpose, the tool holder each comprises a receiving bore with an internal thread and a first bearing region arranged between the front side of the tool holder and the inner thread and a second bearing region arranged at the inner end of the receiving bore. The first support area of ​​the screw-in tool is in contact with the first supp...
