930 Series

Tool 931i0812C

Miniature dovetail features require precision geometry that standard end mills can't deliver. The 931i0812C is a 0.125" diameter solid carbide dovetail mill designed for small workholding slots and undercut profiles where a 30-degree included angle is specified.

The R0.005" corner radius at the dovetail root reduces stress concentration compared to sharp-cornered profiles.
This geometry extends tool life by distributing cutting forces more evenly along the corner transition.
The 0.0787" neck diameter provides clearance while maintaining rigidity at this small scale.
TiB₂ coating adds wear resistance when machining steel and aluminum.
The coating performs well in the interrupted cuts typical of slotting operations.
Two flutes balance chip evacuation with cutting edge strength in these confined geometries.
Applications include precision fixturing, small T-slot preparation, and miniature dovetail keys in tooling components.
