Walter Extends Line of Precision Boring Tools

Walter has extended its line of precision boring tools with new additions of the Walter Precision Boring XT lineup: the Walter Precision XT B5110, B5115, B5120 and B5125.

The B5110 is said to be ideal for fine boring of small diameters. It uses either a solid carbide boring bar option for diameters of 0.039"-0.323" (1-8.2 mm) or an indexable insert boring bar design for diameters 0.315"-0.787" (8-20 mm). The B5115 is designed for precision boring of medium range diameters of 0.748"-6.575" (19-167 mm). Unlike the B5110, which uses the boring bar design, the B5115 utilizes a cartridge style design, as larger space is available for the tool design to accommodate the cartridges.

The B5120, with diameters of 5.827"-25.00" (148-625 mm) covers large diameters with its bridge and cartridge design. The bridges are made of aluminum to accommodate the weight constraints of machine tool spindles. A separate line of “reduced-weight” boring bars in medium-range diameters is also offered through B5125-LWS. The B5125 uses the same cartridges as the B5115 and B5120, reducing cost through modular use of cartridges across tungsten carbide inserts the systems.

These new vibration-free tools provide finish machining of precise bores (IT6–IT8) up to 6 × D with high surface quality, and are reportedly up to three times more reliable and flexible than comparable models. New Walter boring tools employ modular components such as cartridge holders and extensions, which are matched to the system, utilize an extensive range of indexable inserts suited for precision boring and can be used for all material groups. These XT System boring tools are available in Capto connection as well as Walter proprietary NCT and screw-fit adaptions.

They feature internal coolant supply up to the cutting edge, and cartridges for CC and TC with indexable inserts adapted for precision boring. The tools include an option for reverse machining (reverse boring) and are suitable for general metalworking, production of precision parts and WCMT Insert mold and die making.
