2-flute Carbide Tapered Ball-Nose Carving tools - 1/4" (0.250 in.) Shank

  • Geometry - 2-flute tapered high-shear edge grind, ball-nose tip, 1/4 in. (6.35 mm) shank
  • Length - 3.25in. (82.6mm) 0.100 in.
  • Tip diameter - nominal 0.0010 in.
  • Taper angle - nominal 0.10°
  • Runout TIR) - max 0.0005 in.
  • Max. depth of cut - nominal 0.100 in.
  • Anticipated Life - depends on material being cut
  • Material - solid submicrograin carbide
  • Operating RPM - CNC certified operation 1k RPM to 40k RPM


  • 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).


  • Dimensional signage
  • Precision 3D carving
  • 3D contouring and profiling
  • Cabinetry and furniture making
  • 3D millwork
Application Data (tool description for CAM software)
  • Tool Type: Tapered Ball Nose
  • Shank Diameter = 0.250"
  • Half angle (side angle)
    • 0.1250in. (1/8in.) dia. tip - 2.4°
  • Tip radius = nominal 0.001"
  • Stepdown (pass depth, depth per pass)- 2 X tip diameter max
  • Stepover:
    • roughing pass (stepover) = 0.25 X tip diameter
    • finishing pass (clearance, cleanup pass) = 0.10 X tip diameter
  • Depth of Cut (DOC) = 1.60"
  • Spindle RPM (SPEED) = 5 KRPM to 40 KRPM (optimum speed)
  • Feedrate (IPM) = Depends on the material being cut. Do the Sweetspot Test before setting this parameter
    (go to:
  • Plunge rate = 10 IPM to 25 IPM (again depending on material being cut)



  • High Density Urethane (HDU)
  • Softwood - pine, fir, WRC, poplar, red wood ...
  • Hardwood - walnut, redwood, maple, rosewoods ...
  • Plastic - ABS, PVC, HDP, MDP, LDP, celluloid, acrylic ...
