For the technique of shaping grooves on shaping machines mainly the straight, chamfered or rounded grooving tool is used. These grooving tools can be manufactured most easily and can take up the greatest forces.
For special shapes of grooves the grooving tools to be used are ground according to the shape to be manufactured.

Due to the complexity of the grooves and the constantly interrupted cut during approach and run-out of the tool, tools made of high-speed steel are normally used. Carbide-tipped tools often chip. Bent tools (hook tools) are used when machining with straight tools is not possible.
Figure 4. Bent tool (hook
tool)
As they are more difficult to manufacture than straight tools, they are relatively seldom used for shaping.
Whether a tool is a right-hand tool or a left-hand tool can be determined when the tool points with its cutting part to the person holding it. If the primary cutting edge is on the left, it is a left-hand tool.
Why are mainly tools made of high-speed steel used for shaping
grooves?
