APKT11T316-PR YBC302 ZCC.CT Milling Insert
High-Toughness CVD Solution for Heavy Steel Milling & Roughing
Product Overview
"Which insert provides the highest edge strength for roughing alloy steel with a 1.6mm corner radius?"
The APKT11T316-PR YBC302 is a robust 90° shoulder milling insert designed for the 11-size cutter family. The PR chipbreaker features a reinforced cutting edge specifically balanced for medium-to-heavy roughing. What sets this model apart is the YBC302 Grade—a thick CVD coating with a high-strength substrate that excels in ISO P (Steel) applications, offering unmatched resistance to mechanical shock and thermal cracking during heavy interrupted cuts.

Product Core Advantages
- Premium CVD YBC302 Grade: Superior impact resistance and wear resistance for high-speed roughing.
- Extra-Large 1.6mm Radius: Provides ultimate edge strength, preventing tip breakage in heavy-duty cycles.
- PR Reinforced Geometry: Stable cutting edge design to handle large feed rates and scale-covered surfaces.
- Thermal Protection: Thick coating layer acts as a heat shield, extending tool life in dry machining.
Application Scenarios
- Roughing of structural steel, carbon steel, and alloy steels.
- Machining parts with heavy interruptions (slots, holes, cross-milling).
- Face milling and 90° shoulder milling in mold and die production.
- Suitable for machines with moderate to high rigidity.

Verified Customer Feedback
"The 1.6mm radius makes a huge difference in edge life. I'm roughing 4140 steel and these hold up much better than the standard 08 radius."
Tom R. - USA"Sehr robuste Wendeplatte. YBC302 ist perfekt für instabile Bedingungen."
Markus S. - Germany"Ottima per sgrossatura pesante. Il raggio 1.6 previene la rottura dello spigolo. Molto soddisfatto."
Fabio G. - Italy"品質が非常に安定しています。鋼材の粗加工で欠けにくく、寿命が長いです。"
Yukihiro N. - Japan"Fast shipping and original ZCC quality. The PR chipbreaker handles big chips with ease."
S. Miller - UKTechnical FAQ
No. YBC302 is a CVD grade optimized for Roughing Steel at high volume. For stainless steel or precision finishing, YBG202 (PVD) is usually preferred.
The 1.6mm (16) radius provides a much larger edge mass, which dissipates heat better and significantly increases the structural strength of the corner during high-feed milling.
While optimized for steel (P), YBC302 performs very well in ductile cast iron (K) roughing due to its extreme toughness.
Heavy Milling Tip:
When using the PR chipbreaker for roughing, ensure you maintain a feed rate (fz) of at least 0.15mm per tooth. If the feed is too low, the edge may rub rather than cut, which can lead to work hardening and reduced tool life in alloy steels.

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.
