Hoffman Estates, Illinois – This micro deep-hole drill from BIG Kaiser’s Sphinx line provides an option for creating wire EDM starter holes, averaging 5X faster per-hole, according to testing. The addition of this drill to a shop’s toolbox replaces the process of plunge EDM to establish a starter hole. This is especially true when a plate requires many starter holes, where they can be prepared on a standard machining center to shorten process times with no need to exchange tools.
With this drill, holes with a length/diameter ratio of up to 80x are possible in the range of 0.25mm to 1.50mm diameter, in steps of 0.1mm for hole depths up to 20x, 40x, 60x, or 80x length to diameter. A centering/pilot hole of 2x is recommended to begin the process, with the deep-hole drill following with a peck-cycle until the hole is completed.
The Sphinx micro deep-hole drill has a flute- and cutting-edge geometry adapted to this difficult application. Taking in to consideration wear and tear, the drill is constructed of high-quality carbide and abrasion-resistant coating for drilling starting holes in high-strength alloyed tool steels.
BIG Kaiser’s Swiss partner, Sphinx, tested and developed this drill in cooperation with clients specializing in mold making.
