PreciseCarve 1/4" (0.250 in.) Shank Tapered Ball-Nose Carving tools
Specifications
  • Geometry - 1/4 in. (6.35 mm) shank, tapered high-shear flutes, ball-nose tip
  • Length - 2.5in. (63.5mm) 0.010in.
  • Tip diameter - nominal 0.0005 in.
  • Taper angle - nominal 0.03°
  • Runout (TIR) - max 0.0002 in.
  • Max. depth of cut - nominal 0.005 in.
  • Anticipated Life - depends on material being cut (min 50,000 in, western red cedar)
  • Material - solid submicrograin carbide
  • Operating RPM - CNC certified operation 1k RPM to 40k RPM

Benefits

  • High-shear ball-nose tip cuts smooth 3D contours with reduced stepping, and minimal fuzzing
  • High flute volume supports high feed rates / chip loads
  • High aspect ratio for single pass deep-reach cutting
  • Optimized flute geometry and low TIR insures clean cutting, virtually eliminating sanding and fuzz removal
    (when used with low TIR spindles).

Applications

  • Dimensional signage
  • Precision 3D carving
  • 3D contouring and profiling
  • Cabinetry and furniture making
  • 3D millwork
  • Compatible with CarveWright and CompuCarve woodworking systems.
Application Data (tool description for CAM software)
  • Tool Type: Tapered Ball Nose
  • Shank Diameter = 0.250"
  • Half angle
    • 0.0313in. (1/32in.) dia. tip - 6.2°
    • 0.0625in. (1/16in.) dia. tip - 5.4°
    • 0.1250in. (1/8in.) dia. tip - 3.6°
    • 0.2498in. (1/4in.) dia. tip -
  • Tip radius = nominal 0.001"
  • Stepdown = Depth per Pass, use 2 X tip diameter for roughing (clearance) and 0.10 X tip diameter for final cleanup
  • Depth of Cut (DOC) = 1.074"
  • Stepover (for final cleanup pass) = 0.10 X tip diameter
  • Stepover (for roughing, clearance pass) = 0.25 to 0.40 X tip diameter
  • 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 = 10 IPM to 25 IPM (again depending on material being cut)
