B3220 Boring Cartridge

Walter has broadened its line of boring tools with the introduction of the B3220 boring cartridge for axial-radial offset roughing (ARS), expanding on previous methods that were either symmetrical or asymmetrical. This versatile new tool, designed for use with the Walter B3220 but which can be used with the Walter B3221 and B3224 boring tools as well, brings the capabilities of axial-radial offset roughing (ARS) to an array of new applications.

By doubling the tool’s cutting widths, the new cartridge increases metal-removal rates, saving time and, thus, money. Costs are further decreased since the B3220 boring cartridge saves users the need for additional processing steps and tools. In addition, the tool provides good chip control, stable machining conditions and heightened process reliability.

All common ISO materials can be machined with the B3220 boring cartridge, which can accept an extensive range of indexable inserts. It excels at thru hole, line hole, and step cuts and is ideally suited for chassis, large engine and gearbox roughing in the automotive industry. In general engineering it finds application in the roughing of bearing holes, machine housings and compressor housings. In the railway industry it brings new efficiencies to chassis roughing.

  • boring


    Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.
