BACKGROUND / DEVELOPMENT

Standard bits weren't enough.

Early 5-axis wax milling used cutters built for 3-axis work — 10–12 mm cutting lengths, geometries suited to flat reliefs. As jewelry models became more complex and 5-axis strategies demanded rotation through large angles, the limitations of those tools became visible in the output. NS CNC set the target: a tapered ball-end cutter with 26 mm cutting length, 0.1 mm tip, sub-micron runout — manufacturable at production scale. Multiple flute geometry iterations over several years to arrive at the current design. Full-depth wax cutting in a single pass, no roughing, at full feed rate. No other wax milling bit on the market meets this specification.

Standard bits weren't enough.
