BIG KAISER introduces a series of new micro engraving cutters developed and built by its partner Sphinx (Derendingen, Switzerland). Building on Sphinx's microtooling expertise, the solid-carbide engraving cutters' sharp, positive cutting geometry promotes burr-free surface finishes and smooth transitions.

The engravers come standard with a 3mm-dia. shank and are available in a variety of angles (30°/40°/50°/60°/90°) and in two possible point geometries: flat or radius tipped. The radius cutters range from 0.0016" to 0.0039" (0.04mm to 0.10mm), and the flats range from 0.0008" to 0.0059" (0.02mm to 0.15mm).

The microengravers are appropriate for work in most materials ranging from alloyed and unalloyed steels to thermosetting plastics, and even titanium.
