Straight Groove Thread Milling Cutter And Screw Thread Milling Cutter, The Application Is What Is The Difference

The main difference between a straight groove thread milling cutter and a screw thread milling cutter is the type of thread they create.

A straight groove thread milling cutter creates threads with a straight groove pattern that runs parallel to the axis of the cutter. These types of cutters are typically used for producing internal or external threads on cylindrical workpieces.

On the other hand, a screw thread milling cutter creates threads with a helical pattern that spirals around the axis of the cutter. These types of cutters are commonly used for producing screw threads on screws, bolts, and other threaded fasteners.

So, the application of these two types of milling cutters is different depending on the type of thread being produced. Straight groove thread milling cutters are used for cylindrical workpieces, while screw thread milling cutters are used for creating screw threads on fasteners.
