"These 0.0313" (0.8mm) bits have been tuned for cutting ivory, horn, and tusk. The flute capacity has been increased to accommodate a wide range of moisture/oil content. The diameter is ground to within +/-0.0005" (0.0127mm) insuring zero-glue-line inlay cutting. The EMB2 1/32" is the best all-around cutter we have found. This bit has become the general-purpose tool of choice for many cuemakers. The .02" end mill bit is an excellent choice for very small radius cuts. The .0625" end mill bit is a sturdy, general purpose cutter, great for larger inlays that do not require a small radius."
