5-Flute Carbide SRD Kerf Cutters (MM5D8) - (0.125" shank )


  • Depth of cut:
       LDF bits (all point sizes) - 0.460 in. (11.7mm)
       Parallel (drag) kerf  depth - 0.100 in.
  • Deflection compensation (typical):
       0.002 - 0.004 in. typ.
  • Diameter (normal kerf):
       1 point - 0.0140 in. (0.356mm)  0.00025 in. 
       2 point - 0.0280 in. (0.711mm)  0.00025 in. 
       3 point - 0.0420 in. (1.067mm)  0.00025 in. 
       4 point - 0.0560 in. (1.422mm)  0.00025 in. 
       6 point - 0.0840 in. (2.134mm)  0.00025 in. 
  • Runout (TIR) - < 0.0003 in. (0.00762mm)
  • Geometry - 5 flute, Low Strain, Distributed Stress Blended Helix, 1/8in. (3.18 mm) shank, fish tail point
  • Length - 1.5 in. 0.010 in.
  • Anticipated Life: (click for more information)
       5/16 in. Baltic birch plywood - 7,000 to 12,000 linear inches (29,000 linear inches max)
       5/16 in. maple plywood - 5,000 to 8,000 linear inches
  • Material - solid submicrograin carbide 
  • Operating RPM - CNC certified operation 8k RPM to 100k RPM


  • Cuts 5/16 in. Baltic birch plywood at 90 - 110 in./min. @ 40,000 RPM
  • T3 Modified Blended Helix design reduces breakage in sub-optimal cutting environments
  • 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


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