Machine stops caused by chip tangling around the tool or spindle are a common problem in fine boring. With the high-precision nozzle, CoroBore 826 HP directs the high-precision coolant jet to the cutting edge in order to efficiently control and break the chip. Chips are then easily evacuated from the hole. Combined with the user-friendly stepwise scale setting of the tool diameter provides the perfect tool for accurate fine boring.

CoroBore 826 HP is the ideal first choice fine boring tool for requirements in the range of 36–1260 mm (1.417–49.606 inch). It is optimised for process repeatability, hence ensuring excellent surface finish and close hole tolerances.
