APKT11T312-PM YBG302 ZCC.CT Milling Insert
1.2mm Reinforced Corner | The Ultimate Universal PVD Solution
Product Overview
"Looking for one insert to handle interrupted cuts across steel, stainless, and alloys?"
The APKT11T312-PM YBG302 is ZCC.CT's answer to high-versatility milling. Built on the standard 11mm platform, this insert features a significantly larger 1.2mm radius to protect the cutting edge from thermal and mechanical shocks. The YBG302 Grade is a specialized PVD grade that combines a sub-micron substrate with high-thermal stability coating. It is engineered to perform where other inserts chip, making it the perfect choice for interrupted milling and mixed-material production batches.

General Purpose
Core Advantages
- Universal YBG302 Grade: Superior impact resistance across ISO P, M, K, and S groups.
- 1.2mm Radius Security: Specifically designed to prevent corner breakdown during heavy or interrupted cuts.
- PVD Nano-Coating: Excellent thermal stability reduces thermal cracking in dry or semi-dry milling.
- Sharp but Tough: The PM geometry ensures low cutting resistance while maintaining edge integrity.
Common Applications
- Milling of weldments and parts with irregular surfaces.
- Machining of alloy steels, 304/316 stainless, and cast iron.
- Shoulder milling and face milling in multi-material workshops.
- Suitable for high-load operations where tip security is the top priority.

Global Verified Feedback
"The YBG302 is the only grade that survived our interrupted face milling project on welded steel. Highly recommend for rough shops."
J. Dawson - UK"The 1.2 radius provides so much more security than the 0.8. Excellent tool life on cast iron too."
M. Weber - Germany"Ottimo inserto universale. Lo usiamo sia su acciaio che inox senza problemi."
P. Conti - ItalyFrequently Asked Questions
Yes. 11T3 and 1103 both refer to the 3.97mm thickness. These are compatible with all 11-size holders.
Choose the 1.2mm radius when you need maximum edge strength for roughing or when the component drawing specifies a 1.2mm internal fillet. It is far superior at absorbing impacts.
Universal Machining Pro-Tip:
When utilizing the YBG302 grade for interrupted cutting, using compressed air instead of coolant can often prevent thermal shock cracks, significantly extending the life of the PVD coating in steel machining.

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.
