Machine stops caused by chip tangling around the tool or spindle are a common problem in fine boring, according to Sandvik Coromant. With the high precision nozzle, CoroBore 826 high precision coolant tool directs the high-precision coolant jet to the cutting edge in order to 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, the company says.

CoroBore 826 HP is especially useful for requirements in the range of 36 to 1,260 mm (1.417” to 49.606”). It is optimized for process repeatability, hence ensuring excellent surface finish and close-hole tolerances.

To make it easier for users to find the optimum CoroBore 826 HP fine boring solution for their particular requirement, Sandvik Coromant offers assembly kits for a range of hole diameters. The integrated Coromant Capto is especially useful for small-diameter boring of 35.45 to 91.65 mm (1.396” to 3.608”), while the optimal choice for diameters in the range of 91.35 to 154.65 mm (3.596” to 6.089”) is a modular solution with internal counterweight. For large-diameter boring, 154 to 1,260 mm (6.063” to 49.606”), a separate fine boring head can be combined with the flexible CoroBore XL system based on specific machining needs.
