enefits

  • Cuts 5/16 in. Baltic birch plywood at 100 - 120 in./min. @ 40,000 RPM
  • 9mm and 12mm tools are available with  CloseKerf© flute geometry for unprecedented closeness in rule placement. (click for more information)
  • 5 flute geometry insures long life, and low deflection at high feed rates
  • Fish tail point eliminates  backside breakout and splintering
  • Variable helix design provides more efficient chip extraction and minimizes top surface fuzz and splintering
  • Cutting edge geometry eliminates tearing and pulling, yielding smooth, precise edges and sidewalls

Applications

  • Cutting kerf slots in steel-rule die-boards
  • Clean-up cutter for fine inlay pocket finishing.


5 flute SRD kerf cutter


New Flute Geometries for 2 point by 9mm Kerf Cutters 

Our 2 point kerf cutters with a 9mm depth of cut have been redesigned to meet the varying needs of diemakers working in different areas of the packaging industry. Our new "Low-deflection" bit is optimized to cut at 120 - 140 IPM(40 KRPM) with less than 0.004" tip deflection. The "Close-kerf" tool has been designed to allow rule placement on 0.100" centers (5/16", 8mm Baltic birch plywood) with a tip deflection of less than 0.004" while cutting at 95 to 110 IPM (40 KRPM). Both tools retain the long life and superior debris removal that are the hallmarks of this family of tools.
