  • 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, see next table. For using TIP inserts, toolholder seat needs to be modified according to insert profile to ensure clearance. (1) For Star and multi-spindle machines. (2) Maximum parting diameter For inserts, see pages: GIF (A34) GIF (full radius) (A34) GIF-E (W=4-6 full radius) (A30) GIF-E (W=4-6) (A29) GIG (A32) GIM-C (A77) GIM-J (A77) GIM-J-RA/LA (A78) GIM-UT (A79) GIM-UT-RA/LA (A80) GIM-W (A78) GIM-W-RA/LA (A79) GIMF (A27) GIMN (A28) GIMY (A27) GIMY (full radius) (A28) GIP (A33) GIP (flat top W<M) (A31) GIP (full radius W<M) (A31) GIP (full radius) (A33) GIP-E (A29) GIP-E (full radius) (A30) GIPA (full radius W=3-6) (A37) GIPA (W=3-6) (A36) GIPM-A46 / GIP-1250 (A38) GIPY (A36) GITM (A35) GITM (full radius) (A35) TIP-MT (A114) TIP-P-BSPT (A122) TIP-P-BSW (A121) TIP-P-ISO (A117) TIP-P-NPT (A128) TIP-P-UN (A119) TIP-WT (A112).

  • Use the yellow lines on blade for min. and max. overhang.
  • For using TIP inserts, toolholder seat needs to be modified according to insert profile to ensure

clearance. When using a double-ended insert, grooving depth is limited by the insert.
