ZCC.CT ZTFD0303-MG YBG302 Carbide Grooving Insert
Precision 3.0mm (0.118") Parting & Grooving Carbide Insert | PVD Nano-Coated YBG302 Grade
1. Product Overview
Which 3mm grooving insert provides optimal chip control and maximum tool life when parting alloy steel and stainless steel on CNC turning centers?
The ZCC.CT ZTFD0303-MG YBG302 is a double-ended carbide insert engineered specifically for high-efficiency external grooving, face grooving, and deep parting operations. Featuring the heavy-duty -MG chipbreaker geometry, this insert actively curls chips into tight spiral rolls to prevent chip packing and side-wall friction. Manufactured with a ultra-fine tungsten carbide substrate bonded to an advanced PVD TiAlN + TiN nano-coating (YBG302), it offers exceptional resistance to edge wear, thermal cracking, and built-up edge (BUE) across general steel (P15–P30) and stainless steel (M15–M30) machining applications.

Troubleshooting Tips
- Nose Radius Chipping: Ensure cutting edge center height is set strictly to machine center (±0.05 mm).
- Chip Packing in Slot: Increase coolant flow rate into groove slot or elevate feed rate slightly to engage chipbreaker.
- Built-Up Edge (BUE): Increase cutting speed (Vc) to elevate cutting zone temperature or check coolant concentration.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
