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
- CoroBore 826 HP fine boring head available with high precision coolant directed at the cutting edge for excellent chip control and with stepwise click function for easy tool setting.
Features
