Toolmaker Walter USA LLC, Waukesha, Wis., has expanded its Walter Xpress line to include specials with the addition of indexable insert tools for drilling, boring and counterboring.

Using customer-specific parameters for drilling and boring applications, including diameter, number of steps (up to three), step lengths, chamfer angles, relevant cutting tool material options, insert shapes, machine features and cooling, the Walter configuration system designs the required tool and generates comprehensive documentation, including a 3D model. The customer receives a quote within 24 hours, while the bill of materials, work schedule and NC manufacturing programs are created to begin manufacturing the tool to begin production once the order is placed, according to Walter.

The resulting delivery time once an order is placed is 3 weeks, in contrast to the industry standard of 1 to 2 weeks for quotations alone, with tool production taking between 6 and 8 weeks. In addition to the shorter turnaround, the documentation generated by Walter Xpress allows customers to begin using the tool immediately upon receiving it.

Walter Xpress specials for drilling applications are based on Xtra-tec point drills for the diameter range of 0.047" to 1.26" (12 to 32 mm), and Xtra-tec insert drills in the range of 0.65" to 2.32" (16.5 to 59 mm). Solutions for boring and counterboring can be supplied with fixed insert seats or cartridges and have a diameter range of 0.64" to 7.87" (16.5 to 200 mm). There are different cartridge options and all tools can be designed up to drilling depths of five times diameter. The available ISO insert shapes are C, S, M and T and all popular spindles are offered: Parallel shank, HSK, SK, NCT, Capto, Catshank and ScrewFit.
