  • Toycen CM03D Ball End and Corner Radius Grinding Fixture – all Cuttermaster Models

Not so good,  too sloppy not carefully built        Very good Easy center Tool away indexing

Time for a Tune-up  The Basic CM03D  (Mk2) is a simple radius attachment like the old CM03 only much more precise with Clearance Indexing.

The Toycen Helical Radius Attachment CM03 Helical. will interpolate the flute helix at the tip ( July 2021)


The Toycen CM03 MK2  is an improved version of the old CM03 Rad attachment. The CM03 has been around for
quite a while and there are a lot of fans so I didn’t want to mess too much with a good thing but we can do better in several areas, Its time now, and its pretty.

  • Longer Gibs
  • Wider dovetail
  • 360 Degree Swing capable
  • Long Tool Option up to an 8-inch length

  • Center locating step (no need to find spindle center for Ball-end work)
  • Coming soon CM03 MK3  ( helical compensation for steeper flute helix tools)
  • Tool Away from the wheel Y-Axis clearance  Indexing
  • Magnetic Y axis DRO (not optical)

In this video, we feature the Y axis Magnetic DRO With  movable magnetic display
For a demo we change the Corner rad to .080 to .085

1. Move the Y table axis back .005 (increasing the radius to .085)
2. Move the CM023 Y axis in .005 to meet the wheel
3, Move the upper X in so the grind picks up the wheel move on the end


ok this is kinda cool

Helical interpolation at the end of the swing (after a thousand requests in the last 40 years.

Ill let you all know how it goes 🙂
