How to Choose the Right ZCC.CT SN-90 Insert
Selecting the correct ZCC.CT SN-90 insert involves three decisions:
- Material → Grade: Steel → TT7015 / TT8115. Stainless → TT8020 / TT9225. Cast iron → KT-series. Aluminum → US-series.
- Sub-designation → Operation: General turning → SNMG. Finishing → SNMG. Heavy roughing → thicker section.
- IC size → Tool holder: Smaller IC fits compact holders. Larger IC for heavy-duty work.
Tip: For stainless steel work, ZCC.CT TT9225 (CVD M-grade) provides superior wear resistance. For aluminum, use uncoated US-series with sharp-edge geometry.
Frequently Asked Questions
Are these genuine ZCC.CT original inserts?
Yes — all 149 products in this catalog are 100% genuine ZCC.CT originals. Each insert ships in original factory packaging with full traceability.
What is the difference between the SN-90 sub-designations?
The SN-90 family includes sub-designations like SNMG, SNMM, SNMA. Each sub-designation has a specific tolerance class, edge preparation, and intended use. M-class (middle) is the workhorse for general turning; G-class (ground) is precision-sharp for finishing; the heavier variants are for roughing.
What grade should I choose for stainless steel?
For stainless steel work, ZCC.CT recommends TT9225 (CVD M-grade) for general work and TT8020 (PVD grade) for finishing. Choose TT9225 for heavier roughing on tough stainless.
What tool holder do I need for SN-90 inserts?
ZCC.CT SN-90 negative-rake inserts fit standard tool holders. Browse our turning tool holder catalog for compatible options.
How does ZCC.CT compare to Sandvik / Kyocera / Sumitomo?
ZCC.CT's TT-series PVD/CVD-coated inserts are direct competitors to Sandvik GC4325 and Kyocera PR1535 in steel. The CT-series cermet and CVD grades match Kyocera TN60 and Sandvik GC1525. ZCC.CT is also known for cast iron (KT-series) and aluminum (US-series).
