Abstract
The utility model relates to tools used in machining work, in particular to a grooving knife. The grooving knife comprises a knife handle and a knife head, wherein the knife head is arranged on the knife handle and in a disc shape, an installation hole used for installation of the knife handle is formed in the middle of the knife head, and a plurality of grooving blades in sawtooth shapes are evenly distributed outer circular surface of the knife head and are provided with groove edges. Each groove edge comprises a first straight surface edge and a second straight surface edge, wherein each first straight surface edge and each second straight surface edge are symmetrical about the central axis of each grooving blade, an included A is formed between each first straight surface edge and the central axis of each grooving blade, and each first straight surface edge is in transition connection with each second straight surface edge through an arc edge. When a groove of a workpiece is machined, the first straight surface edges and the second straight surface edges machine the groove in shape, the arc edges for transition of the first straight surface edges and the second straight surface edges machine a fillet of the groove, and grooving work can be completed at a time. The grooving knife is simple in structure and good in using effect.
Description
Technical field
The utility model relates to the cutter that machining is used, and is specifically related to a kind of necking tool.
Background technology
