CoroBore® 825 XL and CoroBore® 826 XL are the first choices for large diameter fine boring. The tools can be adjusted radially in order to cover a certain diameter range with one tool. The tools allow precision adjustment in microns in order to achieve close hole tolerances.
Benefits
Reliable system with rigid interfaces between head and cartridge for stable and vibration-free boring
Dedicated grades and geometries for all materials
Excellent surface finish with wiper inserts
Dedicated tool holders optimized for large diameter boring
Close hole tolerances
Available as damped tool (silent tools) for vibration-free boring in diameter 148-315 mm (5.827-12.402 inch) for fine boring even at long overhangs
Also available as lightweight tools: CoroBore lightweight boring tools reduce tool weight and tool change moment, making handling easier and larger diameters possible
