930 Series

Tool 931i1218B

Small dovetails need precision geometry to avoid chipping in the tight corners. The 931i1218B handles 3/16" dovetail profiles in steel and aluminum where both the 45-degree included angle and R0.005" corner radius are specified.

The corner radius eliminates the sharp intersection at the dovetail root, reducing stress concentration in workholding applications where fatigue matters.
AlTiN coating extends tool life in steel by maintaining edge sharpness at higher cutting temperatures.
The 0.0984" neck diameter provides clearance for deeper cuts while maintaining rigidity in this diameter range.
Two flutes balance chip evacuation with cutting edge support.
The geometry works in steels, aluminum, and most machinable metals where dovetail slots, T-slot preparation, or undercut profiles require both the specific included angle and root radius.
