What Are the Different Types of Milling Tools?

Pipe milling machines utilize several different types of milling tools for particular applications. The most common types of milling tools are end mills and slot drills which perform similar actions. Roughing end mills create irregular cuts and slab mills produce wide cuts. Hollow mills are used to smooth cylinders while ball nose cutters produce three dimensional shapes. A wood ruff cutter creates keyways and an involute gear cutter is shaped like a circular saw blade.
A pipe making machine is designed to shape a surface by feeding the work piece against various types of milling tools. These steel tube mill tools are equipped with cutting teeth and rotate against the work piece. Most of these tools are constructed of a heat resistant, high-speed steel material. Each tool is designed to quickly and efficiently perform a specific application. Several different milling tools may be needed to shape and finish a single work piece.
A steel pipe mill is one of the most commonly used milling tools. It has cutting teeth at one end and along the sides. Its appearance is similar to a drill bit and it is typically utilized with vertical milling machines. A slot drill has two fluted cutters with a single tooth in the center and is typically employed for making slotted openings. This milling tool is able to drill directly into a work piece.
