930 Series

Tool 931i1218C

Tight necks on small dovetail mills create clearance problems in confined spaces. The 931i1218C addresses this with a 0.0984" neck diameter on a 0.1875" cutting diameter, allowing access to restricted areas while maintaining the structural integrity needed for 45-degree dovetail cuts.

The TiB₂ coating handles the abrasive nature of aluminum workpieces during undercut operations where heat buildup typically shortens tool life.
The R0.005" corner radius at the dovetail root reduces stress concentration in the finished profile while strengthening the cutting edge against chipping during entry and exit moves.
Two flutes balance chip evacuation with rigidity in this geometry.
Works in aluminum and most other non-ferrous metals for workholding slots, fixture preparation, and undercut profiles where both the included angle and corner radius are specified.
