LIMITATION OF THE MAXIMUM GROOVE DEPTH Due to interference of this part,
the maximum groove depth is
When using the mono block type limited by the cutting diameter.
The maximum groove depth is not limited by the cutting diameter.
When using the modular blade type
The maximum groove depth is limited by the cutting diameter.
Max. Groove Depth (mm) •Shank Diameter=32mm (GYM20 Blade) Max. Groove Depth (mm) •Shank Diameter=40mm (GYM20 Blade)
