930 Series

Tool 931i0818C

Fine-featured dovetails require precision at small scales. The 931i0818C delivers a 0.125" cutting diameter with 45-degree included angle geometry for miniature workholding slots and precision undercut features in steel, aluminum, and most machinable metals.

The R0.005" corner radius strengthens the cutting edge while reducing stress concentration at the dovetail root.
Two flutes provide chip evacuation in the confined geometry typical of small dovetail operations.
The 0.0591" neck diameter offers clearance for deeper cuts while maintaining rigidity at this scale.
TiB₂ coating extends tool life in harder steels where abrasive wear accelerates at small cutting diameters.
The coating maintains sharp edge geometry longer than uncoated tools, which matters when tolerances are measured in tenths on small features.
Applications include precision jigs, fixture components, and instrumentation housings where traditional workholding methods fall short.
