CoroBore BC (Bore Combination) offers an alternative to standard tools that do not meet specific requirements, but the cost and delivery time of a customized solution are prohibitive. Sandvik Coromant personnel use an online program that automatically creates a tool and provides price and delivery information.

Because of the various options offered, a range of multi-step boring applications can be performed. Customers can choose as many as four machining operations in a single tool (as many as two cutting edges per operation). Cutting diameters range from 20 to 200 mm (0.787" to 7.874"), while tool length can be as long as 400 mm (15.75" ), depending on the coupling size. Coupling options include the company’s Capto, HSK Form A and ISO 9766, as well as ISO/Mas-BT/Cat-V tapers. The range of supported coupling models and sizes usually enables direct integration with the machine interface, thus eliminating the need to use a separate basic holder.

The tool’s insert-carrier solutions use cartridges. Compared to fixed insert pockets, this configuration is said to enable efficient cartridge changes. As standard stocked items, both the insert and insert carrier can be replaced on short notice. The cartridges come in three configurations: radially and axially adjustable; axially adjustable only; non-adjustable. All cartridge options feature high-precision coolant nozzles that use coolant pressures of as much as 80 bar (1,160 psi).

In addition to standard ISO inserts, the boring tools can be fitted with 111 inserts, which come with optimized grade options for medium and rough boring. The insert program offers productive geometries and grades for all types of materials and boring operations, according to the company.
