ZCC.CT SNMG190616 YBC151 High-Speed Insert
Precision Performance for Continuous Steel Finishing Operations
Product Overview
"Which carbide insert is best for achieving superior surface finish on steel at high cutting speeds?"
The ZCC.CT SNMG190616 in YBC151 grade is a premium industrial choice designed for high-efficiency finishing of ISO P (Steel) materials. While other inserts struggle with heat at high RPMs, the YBC151 grade utilizes a thick Al2O3 CVD coating to provide an incredible thermal barrier. Combined with the 1.6mm corner radius, this insert delivers exceptional edge strength and surface smoothness in continuous cutting environments.
Core Engineering Advantages
Optimized for high-speed continuous cutting where friction and heat are the primary enemies of tool life.
The 1.6mm radius provides a robust edge that resists chipping while allowing for faster feed rates than smaller radii.
Advanced TiN + Thick Al2O3 multi-layer coating ensures stability under extreme thermal loads.

Recommended Cutting Parameters
| Material Group | Cutting Speed (Vc m/min) | Feed Rate (fn mm/rev) | Depth of Cut (ap mm) |
|---|---|---|---|
| Carbon Steel (HB180-225) | 250 - 450 | 0.25 - 0.70 | 0.5 - 5.0 |
| Alloy Steel (HB225-325) | 180 - 350 | 0.20 - 0.60 | 0.5 - 4.5 |
Primary Applications
- Continuous Turning: Best for long-run finishing where heat buildup is high.
- Materials: Carbon steel, alloy steel, and structural steel.
- Large Components: The R1.6 radius is perfect for high-feed finishing on large shafts and rotors.
System Compatibility
Fully compatible with all ISO standard tool holders including P-type (PSSNR/L), M-type (MSSNR/L), and D-type (DSKNR/L) holders designed for the 1906 size inserts. Ideal for high-rigidity CNC lathes.

What Our Global Customers Say
"Incredible Finish"
We use YBC151 for final finishing on turbine shafts. The surface quality is mirror-like even at 400 m/min speeds.
— David K., Germany 🇩🇪"Top Tier Wear Life"
Compared to our previous European inserts, these last 20% longer on alloy steel finishing runs. Great ROI.
— Mike S., USA 🇺🇸"Stabile e Affidabile"
Il raggio 1.6 garantisce una stabilità incredibile. Rapporto qualità prezzo imbattibile.
— Roberto L., Italy 🇮🇹Pro Machinist FAQ
Q: Can YBC151 handle interrupted cuts?
A: It is primarily designed for continuous cutting. For severe interrupted cuts, we recommend switching to YBC351 for better impact resistance.
Q: Is a 1.6mm radius too large for finishing?
A: On larger components, a 1.6mm radius is ideal as it allows for higher feed rates while maintaining a smooth surface finish (theoretical finish height is lower for larger radii at the same feed).
Q: What makes YBC151 suitable for high-speed machining?
A: The thick Al2O3 layer in the CVD coating acts as a superior insulator, keeping the heat in the chip and away from the carbide substrate, preventing plastic deformation.

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.
Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
