Tool 931i2018C

Small dovetails require precision geometry and edge retention. The 931i2018C delivers a 0.3125" cutting diameter with 45-degree included angle for tight workholding slots and undercut features in steel and aluminum applications.

  • The R0.01" corner radius at the dovetail root reduces stress concentration while strengthening the cutting edge against chipping during interrupted cuts.
  • Three flutes balance surface finish with chip evacuation in the constrained cutting environment typical of dovetail operations.
  • TiB₂ coating extends tool life in steel by reducing crater wear and maintaining sharp cutting edges longer than uncoated carbide.
  • The 0.1772" neck diameter provides clearance for deep slot work while maintaining rigidity for accurate profile generation.
  • Designed for CNC machining centers running conventional dovetail programs in production and toolroom environments.
