What Does a Flute on a .03mm Drill Even Look Like?!

It’s hard to visualize .03mm; it’s smaller than a hair on your head.  It’s even more difficult to fathom drills that size with smooth flutes and well-planned geometries. But, marvels of micro engineering like these are what our partners at Sphinx do best. Whether you’re looking to micro-drill at depths of 2, 4, 6, 20, 60 or even 80xD, we’ve got a solution.

In some rarely-seen photos from the labs at Sphinx, some magnified up to 3,000x, we get an up close look at what these miniature, but powerful drills look like and the work they do.

Sphinx has accomplished some hard-to-believe things with their drills. Some of the smallest offerings, like the Phoenix series, are built from solid carbide for machining hard-to-cut materials including titanium, steel, stainless steel, and cast iron. Ultra-fine AlCrN coatings help both protect your investment and deliver performance – starting on tools as low as Ø0.2mm! There are even coolant-through options starting at Ø1mm in this tiny tooling.
