For machining depth over 13 mm, a single-ended insert is required (GIM, GIMF, GIMY). Tmax for grooving depth depends on part diameter D. For grooving a part with a diameter larger than Dmax, click on "More Info".
For using TIP inserts, toolholder seat needs to be modified according to insert profileto ensure clearance.
