Background Art

Milling cutters are cutting tools typically used in milling machines or machining centers to perform milling operations (sometimes in other machine tools). They remove material at a fixed feed rate within the machine. Milling cutters come in several shapes and many sizes, with a choice of coatings, as well as helix angles and number of cutting faces.

The existing cross-section groove cutter includes a tool handle, a connecting groove, a mounting handle and a tool head. The tool head is fixed to the mounting handle by bolts. When the tool head is worn, it can be easily replaced. Then the tool handle is used to be installed on a milling machine, and the connecting groove is used to position the tool handle.

There are still defects in the above technical conditions: when the above section groove cutter is installed, its cutter head is fixed by fastening bolts, and its stability is not high enough, which reduces the service life of the section groove cutter.

Based on this, the utility model designs a novel cross-section groove cutter to solve the above problems.
