PreciseBIT 2-flute, Micro-engraving, PCB Traces Isolation Bits (EM2E8) - (0.125" shank ) NEW! ZrN coating
extends bit life

Specifications

  • Geometry - 2-flute, "V" point
  • Tip diameter - 0.0050 in. 0.0002 in.
  • Length - indicated 0.010 in. (30 1.50 in. 0.010 in.)
  • Tip angle - nominal  0.5
  • Max. depth of cut - DOC (penetration) varies by tip angle
    • 30° - 0.177 in. (4.5mm)
    • 45° - 0.075 in. (1.9mm)
    • 60° - 0.054 in. (1.4mm)
    • 90° - 0.031 in. (0.8mm)
  • Max runout (TIR) - < 0.0005 in.
  • Shank dia. - 0.1250 in. (3.18 mm) +0.00, -0.0002 in.
  • Max. depth of cut - EFL varies by tip angle
  • Anticipated Life - 3,000 linear inches (fiberglass, CNC milling)
  • Material - solid submicrograin carbide
  • Ring Set - 0.800 in. 0.002 in. (optional)
  • Operating RPM - CNC certified operation 20k RPM to 100k 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.
  • Proprietary ZrN coating extends bit life and improves cut quality

Applications

  • Print circuit trace isolation
  • Engraving plaques, awards, medallions, and labels
  • Custom jewelry fabrication and marking

Notes

  • What is a "Depth Ring"?
  • 30 V-tip designed for scrimshaw engraving in ivory, horn, phenolics, and all hardwoods. Not optimized  for metal engraving, or PCB trace isolation
  • LPKF and T-Tech users must specify the make and model number of their CNC routers to insure that the rings are properly positioned!

Application Data (tool description for CAM software)

  • Tool Type: Engraving Bit
  • Diameter (D) = 0.1250 in. (30), 0.0625 in. (45°, 60°, 90°)
    • 30° D = 0.125 in.
    • 45° D = 0.0625 in.
    • 60° D = 0.0625 in.
    • 90° D = 0.0625 in.
  • Side Angle (A, half angle)
    • 30°: A = 15
    • 45°: A = 22.5
    • 60°: A = 30
    • 90°: A = 45
  • Flat Diamete (F)
    • 30°: F = 0.005 in.
    • 45°: F = 0.005 in.
    • 60°: F = 0.005 in.
    • 90°: F = 0.005 in.
  • Stepdown = Depth per Pass, Pass Depth:
    • Plastic - 0.015 in. (0.38mm)
    • G-10 / FR-4 - 0.010 in. (0.25mm)
    • Aluminum - 0.005 in. (0.13mm)
    • Hardwood - 0.020 in. (0.51mm)
    • Softwood - 0.030 in. (0.76mm)
    • MDF - 0.020 in. (0.51mm)
  • Depth of Cut (DOC):
    • 30° - 0.177 in. (4.48mm)
    • 45° - 0.075 in. (1.92mm)
    • 60° - 0.054 in. (1.38mm)
    • 90° - 0.031 in. (0.8mm)
  • Stepover (for final cleanup pass) = 0.002 in. (0.13mm)
  • Stepover (for roughing, clearance pass) = 0.005 in. (0.25mm)
  • Spindle RPM (SPEED) = 5 KRPM to 60 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 = 5 IPM to 25 IPM (again depending on material being cut)
