Micro drill for faster wire EDM starter holes

Share This Post

BIG Kaiser has introduced a new micro deep hole drill in its Sphinx line that the company says provides a time-saving option for creating wire EDM starter holes, averaging five times faster per hole according to testing the company conducted.

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.New micro drill for wire EDM starter holes

With this drill, holes with a length/diameter ratio of up to 80xØ are possible in the range of Ø.25 mm-1.50 mm, in steps of .1 mm 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 Kaiser’s Swiss partner, Sphinx, was done in cooperation with clients specializing in mould making.
