Dimension T shows the distance from the toolholder to the cutting edge. The grooving depth is the mentioned in ( ). 2.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. 3. 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. 4. GFVS and GFVT are composed of a base-holder and a blade. If the blade should be damaged, replace it with a new blade as listed in the left table. (e.g.) GFVSR2020K-HB + SFR-351B = GFVSR2020K-351B (e.g.) GFVTR2020K-HB + SFR-351B = GFVTR2020K-351B : Std. Item G93
