New Micro Deep-Hole Drill Series from Sphinx Speeds Starter Hole Creation in Wire EDM Operations

Hoffman Estates, IL – This new micro deep-hole drill from BIG DAISHOWA’s Sphinx line provides a time-saving 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 demanding and time consuming 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 80xØ are possible in the range of Ø.25mm-1.50mm, in steps of .1mm for hole depths up to 20/40/60/80xØ. A centering/pilot hole of 2xØ 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 the appropriate high-quality carbide and optimum abrasion-resistant coating for drilling starting holes in high-strength alloyed tool steels.

Testing and development of this drill by BIG DAISHOWA’s Swiss partner, Sphinx, was done in cooperation with clients specializing in mold making.
