Rough-boring tool reduces vibration

Sandvik Coromant has introduced the CoroBore® rough-boring tools.

Single-, twin-, or triple-edged rough-boring tools are offered. The twin-edge CoroBore BR20 uses a differential pitch to reduce vibration and enable use at longer overhangs and larger depths of cut. The tool also features built-in step-boring functionality without any need for an extra shim.

High-precision coolant nozzles are deployed to handle coolant pressure up to 1,015 PSI.

The same tool is also available with Silent Tools™ technology. This damped version is necessary when additional stability is required.

For machinists performing back-boring, the company has released the single-edge CoroBore BR10.

Also offered is the CoroBore BR30, a three-edge tool. Because of its short, rigid design and differential pitch, a low-vibration boring process is attainable, the company states.

These tools are suitable for use with ISO P, M, K, N, S, and H materials.

To support these tools, the company also has introduced the dedicated CoroBore 111 four-edge, rough-boring insert family.
