* Machining with coolant is recommended for Ni-base heat-resistant alloys and titanium alloys. The bold-faced number indicates a center value of recommended cutting condition. Standard Fine pitch ★: 1st Recommendation ✩: 2nd Recommendation Adjust the cutting speed and the feed rate within the above conditions according to the actual machining situation.

For machining center equivalent to BT30, reduce feed rate to 25% or less of the recommended condition. For slotting, internal coolant or center through coolant is recommended. Slotting and pocketing are not recommended for face mill type.
