About ZCC·CT Positive Turning Inserts
ZCC·CT (ZCC Cutting Tools) positive turning inserts are precision ground carbide tools for external and face turning on CNC lathes. The "positive" geometry means a 7° clearance angle on the insert, which makes them ideal for finishing, semi-finishing, and profiling on small to medium lathes where low cutting forces and a sharp cutting edge are critical. ZCC·CT's positive turning line covers the full spectrum of workpiece materials: steel, stainless, cast iron, aluminum, and high-temperature alloys.
Every ZCC·CT insert on this page is genuine OEM product from ZCC Cutting Tools (a wholly-owned subsidiary of ZCC, founded 2003 in Zhuzhou, China). ZCC·CT's proprietary grade families — YBC (CVD-coated steel), YBD (CVD-coated cast iron), YBG (PVD universal), YBM (PVD stainless), YD (uncoated aluminum), and YNG (cermet precision) — set the standard for Chinese carbide inserts at 30-50% below Japanese or European OEM pricing. CNCHome-Beyond is an authorized ZCC·CT distributor; orders placed before 3 PM China time ship same-day from our Hangzhou warehouse with DHL/UPS/FedEx express delivery in 3-7 business days.

About ZCC·CT grade naming: ZCC·CT uses a 4-character grade code that decodes logically. The first letter identifies the base material family: Y = tungsten carbide base, all ZCC·CT inserts start with Y. The second letter identifies the coating family: B = CVD (thick coating for steel/cast iron), G = PVD (thin coating for universal), M = PVD-optimized for stainless, D = uncoated (for aluminum/non-ferrous), N = cermet. The third digit indicates the application range: 1 = finishing, 2 = general, 3 = roughing. The fourth digit is the version number. So YBC251 = tungsten carbide + CVD + general + version 1 (the workhorse steel grade).
ZCC·CT Chip-Breaker Reference (12+ Variants)
ZCC·CT's chip-breaker system is one of the most comprehensive in the Chinese carbide industry. Each chip-breaker is optimized for a specific feed and depth-of-cut range:
| Chip-Breaker | Application | Feed | Depth of Cut | Best With Grade |
|---|---|---|---|---|

How to Choose a ZCC·CT Positive Insert
Step 1: Match the geometry to the operation. For 80% of steel turning applications, choose CCMT (80° rhombic, with hole, positive 7° clearance). For precision finishing at high speed, choose CCGT (cermet edge). For aluminum turning, choose CCGX (lapped uncoated). For profiling with a tighter approach angle, choose DCMT (55°). For 90° shoulder turning, choose SCMT.
Step 2: Match the grade to the workpiece material. Steel → YBC251 (workhorse) or YBC151 (finishing). Stainless/high-temp → YBM251. Cast iron → YBD102 (gray/ductile iron). Aluminum → YD101 (uncoated). Precision steel finishing → YNG151C cermet.
Step 3: Match the chip-breaker to feed and depth of cut. Finishing (0.05-0.15 mm/rev) → 53 / EF / SF. General (0.10-0.25 mm/rev) → HF / HM / EM. Roughing (0.20-0.50 mm/rev) → HR / AHF. Use the table above to find the right combination.
Step 4: Match the insert to the tool holder. ZCC·CT CCMT fits PCLNR/L, DCLNR/L, MCLNR/L, MWLNR/L tool holders (standard 80° positive rake). CCGX aluminum fits the same holders with sharper top clamp. CCMT internal boring bars use S...PCLNR/L, S...MCLNR/L, etc. CNCHome-Beyond carries compatible aftermarket holders at 30-50% below OEM — see our turning tool holder guide and Insert Holder Selector.
Compatible Tool Holders (Standard Positive 7° Rake)
ZCC·CT positive inserts fit the following CNCHome-Beyond tool holder families (all ISO 5610 standard, drop-in compatible with ZCC·CT OEM holders):
- Double-Clamp External Holders (PCLNR/L) — for heavy CCMT roughing
- Multi-Lock External Holders (MCLNR/L) — for general CCMT medium cutting
- Lever-Lock (P-Type) External Holders — for quick-change high-mix production
- Screw-Clamp Boring Bars (S...PCLNR/L) — for internal turning with positive inserts

Frequently Asked Questions
What is the difference between YBC and YBG grades in ZCC·CT?
YBC is ZCC·CT's CVD-coated (thick coating, TiCN + Al2O3) family optimized for steel and cast iron. The thick coating provides exceptional wear resistance for high-volume production. YBG is ZCC·CT's PVD-coated (thin coating, TiAlN) family optimized for universal applications including stainless steel and high-temperature alloys. The thin PVD coating keeps the cutting edge sharp for low cutting force on tough materials. Use YBC for steel and cast iron; use YBG for stainless, high-temp alloys, and mixed-material work.
What is YD101 grade and what is it used for?
YD101 is ZCC·CT's uncoated carbide grade specifically designed for aluminum and non-ferrous metals. The "D" stands for "Diamond-like" polish — YD101 inserts are precision-lapped on the top surface to a mirror finish, which prevents aluminum from sticking (built-up edge) during turning. The sharp cutting edge (no coating to round it over) allows aggressive feeds at 300-1000 m/min on aluminum. YD101 is the workhorse for automotive and aerospace aluminum parts.
What is the equivalent of ZCC·CT CCMT 120408 HM YBC251 in other brands?
ZCC·CT CCMT 120408 HM YBC251 is the industry-standard positive turning insert (12mm IC, 0.8mm nose, 7° positive clearance, HM chip-breaker, CVD steel workhorse grade). Direct equivalents: Sandvik CCMT 120408-PM GC4325, Kennametal CCMT 120408-HM KC7315, Iscar CCMT 120408-HM IC8150, Mitsubishi CCMT 120408-HM US7020, Kyocera CCMT 120408HQ CA6525. All are dimensionally interchangeable on the same external turning tool holder. For grade cross-reference, see our Insert Grade Cross-Reference Tool.
What is the difference between ZCC and ZCC·CT?
ZCC (Zhuzhou Cemented Carbide) is the parent company, founded in 1954 in Zhuzhou, Hunan Province, China. ZCC is one of the largest tungsten carbide producers in the world and supplies cemented carbide blanks to many insert manufacturers. ZCC·CT (ZCC Cutting Tools) is a wholly-owned subsidiary founded in 2003, focused on indexable carbide inserts for turning, milling, grooving, threading, and drilling. ZCC·CT uses the same high-quality carbide substrate as the parent (ZCC powder metallurgy) but adds its own coating technologies (YBC/YBG/YBM families). Today ZCC·CT is one of the top 5 Chinese carbide insert brands.
What is the difference between CCGT (cermet) and CCMT (carbide) inserts?
CCGT uses a cermet cutting edge (ceramic + metal composite, typically TiCN-based) which is harder and more wear-resistant than carbide at high temperatures. Cermet allows higher cutting speeds (up to 350 m/min on steel) and produces a mirror surface finish, but is more brittle and not suitable for interrupted cuts or hard materials. CCMT uses a tungsten carbide cutting edge with CVD or PVD coating, which is tougher but wears faster at high temperatures. Use CCGT for steel precision finishing in stable conditions; use CCMT for general purpose with interruption.
What is the minimum order quantity for ZCC·CT positive turning inserts?
Sample orders start at 1 piece for grade validation. Standard production orders are 10-50 pieces per item. Bulk pricing tiers: 2-9 pieces 6% off, 10+ pieces 12% off (auto-applied at checkout). For custom grades or chip-breakers not in our standard catalog, MOQ is 200 pieces with 6-8 week lead time from ZCC·CT Zhuzhou. See our warranty and return policy for details on grade validation samples.
