Overview

A high quality 3 or 4-flute solid micro-grain carbide tapered cutting tool designed for 3D machine carving. The high-shear ball nose tip cuts smooth 3D contours with reduced stepping and minimal 'fuzz'. This bit also features a high flute volume for high feed rates and the high aspect ratio allows for single pass deep-reach cutting. A great choice for such applications as dimensional signage, precision 3D carving, 3D contouring, cabinetry and furniture making, 3D mill-work, etc. The 1/32" and 1/16" bit are also a drop in replacements for the CarveWright and CompuCarve carving bits.

These bits work well in a surprising range of materials such as:

  • High Density Urethane (HDU)
  • Hardwood - walnut, redwood, maple, rosewood, ebony, epe
  • Plastic - PVC, HDP, MDP, acrylic, polycarbonate
  • Metal - zinc, aluminum, copper, brass, bronze, silver, gold

The applications are nearly endless and include:

  • 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 Type: Tapered Ball Nose
  • Shank Diameter = 0.250"
  • Half angle (side angle)
    • 0.0313" (1/32in.) dia. tip: 6.2°
    • 0.0625" (1/16in.) dia. tip: 5.4°
    • 0.1250" (1/8in.) dia. tip: 3.6°
    • 0.2498" (1/4in.) dia. tip: 0.1°
  • Tip radius = nominal ±0.001"
  • Stepdown (pass depth, depth per pass)- 2 X tip diameter max
  • Stepover:
    • roughing pass (stepover) = 0.25 X to 0.40 X tip diameter
    • finishing pass (clearance, cleanup pass) = 0.10 X tip diameter
  • Depth of Cut (DOC) = 1.074"
  • Spindle RPM (SPEED) = 5 KRPM to 60 KRPM (optimum speed)
  • 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)
