Technical information for Threading Technical information for Threading GRADE & THEIR APPLICATIONS Anvil Change Recommendation Grade Use TTIP30 TTIM45 TTIG30 TTIN30 Pitch A Some Pitch to Diameter combinations require an Anvil change. If an Anvil change TPI mm is required , use STM- R Anvils for EX-RH toolholders and for IN-LH boring bars. Use STM-L Anvils for IN- RH toolholders and for EX-LH boring bars. 2.5 109 Special 5Holderv I I iACMESTUB ACME 3 83.57 Required v/ AC Co AC o£ ^V//o- rC *< V, 7 / TRAPEZ (DIN 103)ROUND (DIN 405) TiN coated , yellow color, the universal TiALN coated, black color; Multi-Layer The grade designation is according to Ceramic grade, good toughness, thegrade for general steel, recommendedPVD coated for stainless steel & steelfor rigid cutting conditional.medium machiningpressing thread inserts with new chip-breaker, compatible with all series ofstainless steel & steel < HRC 50medium machiningcollapse edge resistance and wearresistance.
