  • Operating RPM - CNC certified operation 4k RPM to 40k RPM

Benefits

  • spiral geometry insures efficient debris removal
  • Cutting edge geometry virtually eliminates chatter at high feed rates
  • 60° & 90° tips optimized for engraving non-ferrous metals, hardwoods, phenolics, stabilized woods and composite minerals.

Applications

  • Carving / engraving wood, HDU, and acrylic signs
  • Engraving plaques, awards, medallions, name tags and labels
  • Custom edging and chamfering


Application Data (tool description for CAM software)

  • Tool Type: V-Bit
  • Diameter (D) = 0.2500 in.
  • Included Angle (A, total angle)
    • 30°: A = 30
    • 45°: A = 45
    • 60°: A = 60
    • 90°: A = 90
  • Stepdown = Depth per Pass, Pass Depth:
    • Plastic - 0.118 in. (3.0mm)
    • G-10 / FR-4 - 0.040 in. (1.0mm)
    • Hardwood - 0.118 in. (3.0mm)
    • Softwood - 0.250 in. (6.4mm)
    • MDF - 0.188 in. (3.0mm)
  • Depth of Cut (DOC):
    • 30° - 0.467 in. (11.9mm)
    • 60° - 0.217 in. (5.5mm)
    • 90° - 0.125 in. (3.2mm)
  • Stepover (for final cleanup pass) = 0.010 in. (0.13mm)
  • Stepover (for roughing, clearance pass) = 0.015 in. (0.25mm)
  • Spindle RPM (SPEED) = 5 KRPM to 40 KRPM
  • Feedrate (IPM) = Depends on the material being cut. Do the Sweetspot Test before setting this parameter
    (go to: http://www.precisebits.com/tutorials/calibrating_feeds_n_speeds.htm).
  • Plunge rate = 40 IPM to 25 IPM (again depending on material being cut)
