Rough boring tools

Roughing is primarily focused on metal removal and is performed to open up an existing hole made by methods such as pre-machining, casting or forging. Rough boring prepares the hole for finishing. For optimized boring, general boring, large diameter- and lightweight boring see the selection of tools, presented below in the overview. To eliminate vibration when machining with long overhangs, damped tools are available.
