microbrocas

Coated carbide micro deep hole drills manufactured by Sphinx Tools can reliably create wire EDM starter holes up to 5x faster than traditional wire erosion techniques.

BIG Kaiser’s partner, Sphinx Tools Ltd. (Derendingen, Switzerland), is a leader in the innovation, production and distribution of precision tools for the metalworking and medical industry; manufacturing high precision solid carbide and high speed steel (H.S.S.) drills, micro drills and micro end mills.

Precisely ground micro drills, especially those that are made of tough, nano-grade carbide and are small enough to drill accurately through a single hair follicle, aren’t exactly a dime a dozen.
