Dimensions in mm. For each diameter the usable lengths shown are available in 1 – 5 mm steps. Other combinations, special radii and intermediate diameters custom made.

When to choose the cylindrical neck

Narrow ribs and slots with vertical walls: the neck, slightly smaller than the cutting diameter, goes all the way down.
Rest machining in corners and deep details after a larger cutter.
For drafted walls or depths beyond 10 – 12 times the diameter choose the reinforced tapered neck.
