ZCC.CT RCKT1204MO-DM YBC351 Milling Insert
The Heavy-Duty Choice for Precision Copy & Face Milling
Product Overview
The ZCC.CT RCKT1204MO-DM in YBC351 grade is a high-performance round milling insert built for durability. The round geometry provides the strongest possible cutting edge, making it perfect for 3D profiling and copy milling. The YBC351 grade utilizes a thick CVD coating combined with a high-toughness substrate, specifically designed for ISO P25-P40 steel applications involving interruptions or unstable conditions. The DM chipbreaker balances sharpness with edge reinforcement to handle varying depths of cut without fracturing.
Core Advantages
- ✔ Strongest Edge Geometry: Round shape (RCKT) distributes cutting forces evenly, minimizing edge chipping.
- ✔ YBC351 Impact Resistance: Optimized for tough roughing where chip thickness varies or shocks are present.
- ✔ DM Chipbreaker: Engineered for medium-duty machining (DM) with excellent heat dissipation.

Global Reviews
⭐⭐⭐⭐⭐
"Best value for mold base roughing. YBC351 takes hits that would break other inserts."
— Robert K., USA 🇺🇸⭐⭐⭐⭐⭐
"Sehr robuste Wendeplatte. Perfekt für das Schruppen von Baustahl."
— Thomas H., Germany 🇩🇪⭐⭐⭐⭐⭐
"Reliable in 42CrMo4. DM chipbreaker handles high feed rates well."
— Paolo L., Italy 🇮🇹⭐⭐⭐⭐☆
"Very consistent quality. Works great on our Fanuc milling centers."
— Akira Y., Japan 🇯🇵FAQ
Q: Why use a round insert for milling?
A: Round inserts have the strongest geometry. As the depth of cut changes, the lead angle changes, which thins the chips and allows for higher feed rates.
Q: Can YBC351 handle stainless steel?
A: It is primarily for P-class steel. For stainless steel, we recommend ZCC.CT's YBM series.
Q: What does "DM" stand for?
A: DM is the chipbreaker designation for Medium-Rough machining. It provides a balanced rake angle for stability and heat resistance.
SEO Tech Tip: When using round inserts for roughing, remember that the effective lead angle decreases as depth of cut decreases. This allows for significantly higher feed per tooth (fz) to maximize productivity.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
