ZCC.CT SCMT120408-HR YBC152 Turning Insert

Next-Gen CVD Grade for Maximum Removal Rates in Steel Roughing

Product Overview

"Which carbide insert grade provides the best tool life for heavy-duty roughing of carbon and alloy steels under high-speed conditions?"

The ZCC.CT SCMT120408-HR in the advanced YBC152 grade is a powerhouse for ISO P (Steel) machining. Featuring a specialized thick Al2O3 CVD coating, the YBC152 grade is engineered for high-speed stability and exceptional wear resistance. The HR Chipbreaker (Heavy Roughing) is characterized by its reinforced cutting edge and wide chip pocket, specifically designed to handle large Depths of Cut (DOC) and high feed rates without sacrificing tool integrity.

Key Performance Advantages

● YBC152 Grade Technology: Enhanced thermal stability ensures consistent performance during high-speed dry or wet machining.
● HR Heavy Roughing Geometry: The robust edge design prevents chipping even when encountering forging scales or casting skins.
● Square Stability: 90° S-shape provides high seating stability in the tool holder under heavy radial forces.

Trusted by Machinists Worldwide

★★★★★

"The HR chipbreaker is unmatched for roughing out large parts. YBC152 lasts 20% longer than the previous 151 grade in our alloy steel tests."

— Robert D., USA 🇺🇸
★★★★★

"YBC152 ist hervorragend für die Hochgeschwindigkeitsbearbeitung. Sehr stabil und zuverlässig."

— Dieter S., Germany 🇩🇪
★★★★★

"Unbeatable value. Using it for heavy roughing on forgings, it handles the intermittent crust very well."

— Marco V., Italy 🇮🇹
★★★★☆

"Very stable under load. Fast shipping and high quality from ZCC.CT."

— Tanaka H., Japan 🇯🇵

Machinist Support (FAQ)

Q: What is the difference between YBC151 and YBC152?

A: YBC152 is the upgraded generation featuring a thicker Al2O3 layer and improved substrate, offering significantly higher wear resistance at elevated temperatures.

Q: Is the HR chipbreaker suitable for finishing?

A: No, HR is designed for roughing (large DOC). For finishing, please look for the HF or HM chipbreakers which offer finer chip control at lower feed rates.

Q: Can these be used for stainless steel?

A: While they can machine stainless in a pinch, YBC grades are optimized for Steel (P). For Stainless Steel (M), we recommend ZCC.CT YBM grades.

Equivalent Models: Sandvik SCMT 432-PR/QR, Kyocera SCMT 432-HR, Mitsubishi SCMT 432-RP.

Troubleshooting: If chipping occurs, reduce feed rate (fn). If the cutting edge wears prematurely, ensure sufficient coolant or reduce cutting speed (Vc).

Workpiece Matrix: Carbon Steel (P10-P25), Alloy Steel (P10-P25), Cast Steel.

 

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. Delivery generally takes 5–20 business days, depending on your destination and shipping method. Customs clearance or unforeseen delays may affect delivery times. A tracking number is sent by email after shipment.
