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. Designed for use with the Walter B3220, the tool brings the capabilities of ARS to a range of applications. The cartridge can be used with the Walter B3221 and B3224 boring tools as well.

By doubling the tool’s cutting widths, the cartridge increases metal removal rates and reduces the need for additional processing steps and tools, saving time and therefore money. In addition, the tool provides good chip control, stable machining conditions and heightened process reliability, the company says.

All common ISO materials can be machined with the B3220 boring cartridge, which can use a range of indexable inserts. The tool is well-suited for through-hole, line-hole and step cuts. Applications include chassis, large engine and gearbox roughing in the automotive industry; roughing on chassis for the railway industry; and general engineering applications such as roughing bearing holes, machine housings and compressor housings.
