Kyocera DC 55° Diamond Positive Inserts — DCMT, DCGT, DCET Carbide Turning
Kyocera 55° diamond positive inserts manufactured to ISO 1832 standards using Kyocera's full grade system (PR930, PR1125, PR1225, TN60, CA5515, CA5525, CA6525, PV720). The DC 55° positive-rake geometry provides lower cutting forces than negative inserts, making it the preferred geometry for finishing, profiling, and small-diameter work on steel, stainless, cast iron, and aluminum.
This catalog covers 68 Kyocera SKUs across DCGT (38, ground sharp), DCMT (29, molded chipbreaker), and DCET (1, edge-prep specialty) geometries. Ten grade families are available — drop-in compatible with Kyocera's PR series (CVD steel), TN series (cermet), PV series (PVD), and CA series (CVD stainless/cast iron).

Each insert is sourced through Kyocera's authorized distribution channels and ships in original Kyocera factory packaging with full Kyocera grade and lot traceability. Kyocera's premium carbide substrates, CVD/PVD coatings, and edge-preparation processes are specified across the full PR / TN / PV / CA grade families — providing the consistent performance and reliability that has made Kyocera the leading Japanese cutting-tool brand.
About Kyocera DC 55° Diamond Positive Inserts
The DC 55° diamond (rhombic) positive geometry with 7° positive rake provides lowest cutting forces among standard positive turning geometries. With 4 usable cutting edges per insert, a narrow 55° point angle, and a positive rake that reduces radial forces, DC inserts are ideal for:
- Profile and contour finishing — narrow 55° point provides better clearance than 80° CN inserts
- Thin-walled components — minimum deflection on flexible workpieces
- Small-diameter turning — Swiss-type lathes, medical components
- Long slender shafts — L/D ratios above 10:1 where chatter is a concern
- Aluminum and non-ferrous — positive rake prevents BUE on soft materials
The DC family includes three sub-designations:
- DCGT — ground sharp edge with 55° point and 7° positive rake. Tighter tolerances for finishing and aluminum work. (38 SKUs in our catalog)
- DCMT — molded chipbreaker with 55° point and 7° positive rake. The most versatile DC style for general-purpose work. (29 SKUs in our catalog)
- DCET — DC-style with USF edge prep for specialty stainless work. (1 SKU in our catalog)
Kyocera Corporation (Kyoto, Japan) is one of the world's leading manufacturers of CNC cutting tools, with over 60 years of tooling expertise. The Kyocera PR series (CVD-coated steel), TN series (cermet), PV series (PVD-coated stainless), and CA series (CVD stainless / cast iron) represent decades of grade development — each grade optimized for specific ISO application ranges and cutting conditions.

How to Choose the Right Kyocera DC Insert
Selecting the correct Kyocera DC 55° diamond positive insert involves four decisions:
- Material → Grade: Steel → PR930 / PR1125 / PR1535 / PR1225. Stainless → CA5525 / CA6525 / PV720. Cast iron → CA5515. Aluminum → TN60 (uncoated cermet). Steel finishing → TN60 cermet.
- Operation → Chipbreaker / edge prep: General turning → GK (DCMT). Heavy / high-feed → HQ (DCMT). Sharp aluminum finishing → F edge prep (DCGT). Slight-hone steel finishing → U edge prep (DCGT). Precision stainless → CK / USF edge prep.
- IC size → Tool holder: IC 6.35 mm (0702) → SDJCR/L 07 holders. IC 9.525 mm (11T3) → SDJCR/L 11 holders.
- Hand → Lathe configuration: R-hand inserts are standard for most lathes. L-hand inserts needed for Swiss-type or dual-direction turning. DCGT inserts come in EL/ER/FL/FR variants for full flexibility.
Tip: For general steel work, start with DCMT11T308GK CA5525. For aluminum, use DCGT11T304ER-U TN60 cermet. For stainless, start with DCMT11T304HQ CA6525.
Frequently Asked Questions
Are these genuine Kyocera original inserts?
Yes — all 68 products in this catalog are 100% genuine Kyocera originals manufactured by Kyocera Corporation in Kyoto, Japan. Each insert ships in original Kyocera factory packaging with full traceability. Kyocera's grade designations (PR930, TN60, CA5525, etc.) are industry-standard references backed by decades of carbide substrate and coating development.
What is the difference between DCMT and DCGT?
DCMT and DCGT are both 55° diamond positive inserts with 7° positive rake, but differ in manufacturing precision:
- DCMT — molded chipbreaker on top. Cost-effective for general turning operations where the molded chipbreaker geometry controls chip flow.
- DCGT — ground precision edge without chipbreaker. Tighter tolerances (±0.025 mm vs ±0.13 mm for DCMT) for finishing and aluminum work where sharp edges matter.
Use DCMT for general steel/stainless work; use DCGT for aluminum, cermet finishing, and precision applications.
What is the difference between PR930, PR1125, and PR1225?
All three are Kyocera's CVD-coated P-grades for steel turning, but with different operating ranges:
- PR930 — most versatile, P10-P30. The standard choice for general steel turning.
- PR1125 — P10-P25. Optimized for high-speed steel turning with sharper cutting edge.
- PR1225 — P15-P30. Premium-grade with thicker coating for tougher steel work.
Choose PR930 for general work, PR1125 for high-speed finishing, PR1225 for premium OEM applications.
Why use a positive insert instead of a negative insert?
Positive inserts (DC, CC, TC, VB, etc.) provide several advantages over negative inserts:
- Lower cutting forces — the 7° positive rake reduces radial forces by 30-50%
- Better for thin sections — minimizes workpiece deflection and chatter
- Sharper cutting edges — ground variants (DCGT, CCGT) have minimal edge prep
- Better profile clearance — 55° point is narrower than 80° CN, providing better profiling capability
Drawbacks: positive inserts have weaker cutting-edge strength than negative inserts and are not recommended for heavy roughing or interrupted cuts. Choose positive for finishing, thin sections, profiling, and Swiss-type work; choose negative (CNMG, DNMG, etc.) for heavy roughing.
What tool holder do I need for DC inserts?
DC 55° diamond positive inserts (with 7° positive rake) require positive-rake tool holders. Common holders include:
- SDJCR/L — screw-clamp external holders, the most common
- SDNCN — neutral external holders
- SDQCR/L — 107.5° lead angle holders for profiling
- SDUCR/L — boring bars for internal turning
Browse our turning tool holder catalog for compatible options.
What is TN60 cermet and when should I use it?
TN60 is Kyocera's TiC/TiN cermet grade — a ceramic-metal composite used uncoated for finishing operations on:
- Steel — achieves Ra 0.4-0.8 µm surface finish at low-to-medium speeds (100-200 m/min)
- Aluminum and non-ferrous — uncoated cermet prevents BUE (built-up edge) on soft metals
- Cast iron — finishing at low speeds with high wear resistance
Avoid TN60 on interrupted cuts, stainless steel, or heavy roughing — these applications need tougher coated carbide (CA5525, PR1535) instead.
