930 Series

Tool 930i1618B

Quarter-inch dovetail work requires precision at scale. The small cutting diameter means less cutting force distribution, so edge geometry becomes critical for maintaining dimensional accuracy in tight workholding features and miniature T-slots.

The 930i1618B uses a 45-degree included angle with sharp corners to produce clean entry into steel and aluminum without edge buildup that would compromise slot dimensions.
AlTiN coating provides the thermal barrier needed when cutting steels at the higher surface speeds this diameter range allows.
The 0.1378" neck diameter clears the undercut while maintaining rigidity for chatter-free operation.
Two flutes balance chip evacuation with structural integrity in the reduced neck section.
This geometry handles workholding fixture prep, small component T-slot work, and precision dovetail joints where tolerances matter.
