Crossing a Widia (Hanita) tool to RobbJack
There's no universal part-number standard across cutting-tool brands, so we match on what actually determines performance: cutting diameter, flute count, end type and corner radius, length of cut, work material, and coating.

RobbJack matches your size to its nearest standard (for example RobbJack's .030 corner radius for a .031), and you can require an exact match or allow a near-size upgrade.
