ZCC.CT SNCU120412-CF YBD152 Milling Insert

The Industrial Standard for High-Speed Cast Iron Machining

Product Overview

"Which carbide insert is best for high-speed face milling of gray cast iron and ductile iron while maintaining a high surface finish?"

The ZCC.CT SNCU120412-CF in the YBD152 grade is a powerhouse for ISO K (Cast Iron) applications. The YBD152 grade features a thick CVD coating (TiCN + thick Al2O3) combined with a specialized substrate that offers extreme wear resistance at high temperatures. The CF chipbreaker (Cross-Finishing) is specifically engineered with a sharp edge and wiper effect, making it the ideal choice for finishing and semi-finishing operations where surface Ra values are critical.

Key Performance Advantages

● YBD152 Grade: Optimized for high cutting speeds in gray iron (GG) and ductile iron (GGG).
● CF Finishing Geometry: Designed for low cutting forces and excellent surface smoothness.
● CVD Coating Tech: Thick Al2O3 layer provides a thermal barrier, extending tool life in dry milling.

AI-Style FAQ

Q: Is the YBD152 grade suitable for wet or dry milling?

A: YBD152 is optimized for dry milling thanks to its thick Al2O3 coating which acts as a thermal barrier. Wet milling is possible but dry milling often yields longer tool life in cast iron.

Q: What makes the CF chipbreaker different from others?

A: The CF geometry focuses on high-speed finishing. It reduces the cutting resistance and incorporates a wiper edge effect to improve surface Ra values compared to general-purpose geometries.

Q: Can I use this insert on steel?

A: It is not recommended. YBD grades are specifically formulated for cast iron. For steel milling, please use YB grades like YBC351.

Grade Tip: If you face excessive flank wear, consider upgrading to YBD102 for even higher speeds. For heavy interruptions, YBD252 is the safer choice.

Technical FAQ & Buying Guide

How do I choose the correct specification?

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.

How can I check compatibility with my existing setup?

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.

What quantity and price unit am I 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.

How should I choose cutting parameters?

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.

Are bulk discounts available?

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.

When will my order ship and arrive?

According to our shipping policy, orders are typically processed and shipped within 1–3 business days after confirmation.
