Both the CoroBore® 825 XL and the CoroBore® 826 XL are ideal devices to use in large diameter fine boring, and both devices can be adjusted radially to allow for the coverage of a specific diameter range with a single tool. The 825 XL and the 826 XL feature reliable systems complete with rigid interfaces between the cartridge and head, resulting in vibration-free boring.
These devices are compatible with a large range of CoroTurn 107 and 111 inserts, and are manufactured from high strength aluminum which helps to reduce the device's weight. The hard coating found on these increases surface protection, and the devices feature dedicated grades and geometries for all materials.
