How to Choose the Right Sumitomo TB-TP-TC-60-TRIANGLE Insert
Selecting the correct Sumitomo TB-TP-TC-60-TRIANGLE insert involves three decisions:
- Material → Grade: Steel → AC6020M / AC6030M. Stainless → NC5330 / NC5340. Cast iron → NC40 series. Aluminum → GC3040 / KW10.
- Sub-designation → Operation: General turning → TPGT. Finishing → TPGT. Heavy roughing → thicker section.
- IC size → Tool holder: Smaller IC fits compact holders. Larger IC for heavy-duty work.
Tip: For stainless steel work, Sumitomo NC5330 / NC5340 (CVD M-grade) provide superior wear resistance. For aluminum, use uncoated GC3040 or KW10 with sharp-edge geometry.
Frequently Asked Questions
Are these genuine Sumitomo original inserts?
Yes — all 39 products in this catalog are 100% genuine Sumitomo originals manufactured by Sumitomo Electric Industries in Itami, Japan. Each insert ships in original Sumitomo factory packaging with full traceability.
What is the difference between the TB-TP-TC-60-TRIANGLE sub-designations?
The TB-TP-TC-60-TRIANGLE family includes sub-designations like TPGT, TCMT, TPMT, TBGT. 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, Sumitomo recommends NC5330 (CVD M-grade) for general work and NC2020 (cermet) for finishing. NC5340 is the premium choice for heavy roughing on tough stainless.
What tool holder do I need for TB-TP-TC-60-TRIANGLE inserts?
Sumitomo TB-TP-TC-60-TRIANGLE positive-rake (7° positive rake) inserts fit standard tool holders. Browse our turning tool holder catalog for compatible options.
How does Sumitomo compare to Sandvik / Kyocera?
Sumitomo's AC-series PVD/CVD-coated inserts are direct competitors to Sandvik GC4325 and Kyocera PR1535 in steel. The NC-series cermet and CVD grades match Kyocera TN60 and Sandvik GC1525. Sumitomo's GC-series aluminum grades are highly regarded for non-ferrous work.
