1. Product Overview
Searching for the sharpest milling insert for aluminum, copper, or other non-ferrous alloys under normal machining conditions? The ZCC.CT APKT11T304-LH YD101 is purpose-built for exactly this application. Featuring an ultra-fine grain uncoated carbide substrate (YD101) — one grade finer than YD201 — this insert delivers an exceptionally sharp cutting edge with near-zero built-up edge tendency. Combined with the left-hand (LH) positive chipbreaker geometry and a R0.4 corner radius, it produces mirror-quality surface finishes on non-ferrous workpieces at high cutting speeds. Ideal for face milling, shoulder milling, and finishing passes on aluminum alloys, copper, brass, and bronze components.

2. Key Features
🔬 Ultra-Fine Grain YD101
Finer grain structure than YD201 — delivers a sharper, more durable cutting edge with superior resistance to micro-chipping on non-ferrous materials.
📐 Zero Built-Up Edge
Uncoated substrate has no chemical affinity with aluminum or copper. Eliminates material adhesion and ensures consistent surface quality throughout the tool life.
⚙️ R0.4 Corner Radius
Fine nose radius optimized for finishing passes. Achieves Ra <0.8µm surface finish on aluminum alloys under correct cutting parameters.
📐 LH Positive Chipbreaker
Left-hand geometry reduces cutting forces and directs chips away from the machined surface — critical for long-chipping non-ferrous materials.
📦 10 pcs/Pack
Factory-sealed, individually inspected. Dimensional consistency across the full batch ensures balanced cutting in multi-insert cutter setups.
🌎 ISO APKT Standard
Drop-in compatible with all APKT11T3 cutter bodies. Interchangeable with Sandvik, Iscar, Kennametal, and Mitsubishi equivalents.

| Grade | Coating | ISO Group | Best For | vs YD101 |
|---|---|---|---|---|
| YD101 | Uncoated | N | Non-ferrous, normal conditions | — (this product) |
| YD201 | Uncoated | K, N | Cast iron & non-ferrous, unfavorable | Coarser grain; better for cast iron |
| YBG102 | CVD TiCN+Al₂O₃ | P, M | Steel, stainless steel | Not suitable for non-ferrous |
| YBG202 | PVD TiAlN | M, S | Stainless, superalloys | Not suitable for non-ferrous |
| YBD152 | CVD Diamond | N | Aluminum, CFRP (high volume) | Longer life; higher cost |
YD101 vs YD201: YD101 has a finer grain size, producing a sharper edge and better surface finish on non-ferrous materials under normal conditions. YD201 is tougher and better suited for interrupted cuts and cast iron.

💡 Grade & Material Selection Tip
YD101 (Ultra-Fine Grain Uncoated) is the go-to choice for non-ferrous materials (aluminum, copper, brass, bronze) under normal machining conditions. Its ultra-fine grain structure produces a razor-sharp edge that stays clean and sharp throughout the cut. Key rule: never use coated inserts on aluminum — the coating chemically bonds with the workpiece, causing built-up edge and poor surface finish. For cast iron, switch to YD201. For steel, use YBC302 or YBG102. For stainless and superalloys, choose YBG202. Always match the ISO material group (P/M/K/N/S/H) to the grade’s primary application range for optimal tool life and surface quality.
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.
