How to Choose the Right Korloy GROOVING Insert
Selecting the correct Korloy GROOVING insert involves three decisions:
- Material → Grade: Steel → TT7015 / TT8115. Stainless → TT8020 / TT9225. Cast iron → KT-series. Aluminum → US-series.
- Sub-designation → Operation: General turning → MGMN. Finishing → MGMN. Heavy roughing → thicker section.
- IC size → Tool holder: Smaller IC fits compact holders. Larger IC for heavy-duty work.
Tip: For stainless steel work, Korloy TT9225 (CVD M-grade) provides superior wear resistance. For aluminum, use uncoated US-series with sharp-edge geometry.
Frequently Asked Questions
Are these genuine Korloy original inserts?
Yes — all 30 products in this catalog are 100% genuine Korloy originals. Each insert ships in original factory packaging with full traceability.
What is the difference between the GROOVING sub-designations?
The GROOVING family includes sub-designations like MGMN, FGD, FMM, FGM. 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, Korloy 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 GROOVING inserts?
Korloy GROOVING positive-rake (7° positive rake) inserts fit standard tool holders. Browse our turning tool holder catalog for compatible options.
How does Korloy compare to Sandvik / Kyocera / Sumitomo?
Korloy'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. Korloy is also known for cast iron (KT-series) and aluminum (US-series).
