Dimension T shows available grooving depth. 2. φD1 shows toolholder head diameter to L3. 3. The value ( ) of Face Grooving Dia. (φD MAX.) is the maximum outer diameter value after the initial groove between MIN.~MAX. (It is possible to widen the groove to infinity ∞). The value ( ) of Face Grooving Dia. (φD MIN.) is the minimum diameter of the boss which remains in the center when widening the groove width to a smaller value after the initial groove between MIN.~MAX. 4. Standard toolholders are designed with the edge position 1.0mm above the center. When using non-standard toolholders, set the edge position 1.0mm above the center.  Selection of Toolholder & Insert Toolholder Right-hand (R) Toolholder Left-hand (L) Insert Right-hand (R) Insert Left-hand (L)  : Std.
