Tool 931i1248C
Small dovetail features require precision without sacrificing tool rigidity. The 931i1248C delivers a 0.1875" cutting diameter with a 120° included angle for workholding slots and undercut profiles where corner radius geometry is specified.
- The R0.005" corner radius at the dovetail root reduces stress concentration in the finished part while creating a stronger cutting edge that resists chipping during interrupted cuts.
- TiB₂ coating extends tool life in aluminum by reducing adhesion and heat buildup at the cutting edge.
- The 0.0787" neck diameter provides clearance for deep slot work while maintaining sufficient rigidity for the two-flute geometry.
- Works effectively in aluminum and most other non-ferrous metals where dovetail profiles with radiused roots are required for fatigue resistance.
