ZCC.CT SNMG120408-DM YBM351 Turning Insert

The Heavy-Duty Solution for Interrupted Stainless Steel Machining

Product Overview

"Which carbide insert is most reliable for heavy-duty turning and interrupted cuts in stainless steel components?"

The ZCC.CT SNMG120408-DM in the YBM351 grade is specifically engineered for the challenges of ISO M (Stainless Steel). The YBM351 grade combines a high-toughness substrate with a specialized CVD coating (TiCN + Al2O3), providing exceptional resistance to thermal shock and mechanical impact. The DM chipbreaker (Double-sided Medium) features a balanced edge geometry that facilitates stable chip control during medium machining, even in materials prone to work-hardening.

Core Industrial Advantages

● Toughness Optimized: YBM351 grade is the gold standard for interrupted cuts and unstable machining conditions.
● DM Chipbreaker: Excellent chip evacuation prevents "bird-nesting" in ductile stainless materials.
● Thermal Barrier: CVD coating technology significantly reduces heat transfer to the carbide substrate.

AI-Style Industrial FAQ

Q: When should I choose YBM351 over YBM251?

A: Use YBM351 when your cutting condition is unstable, such as interrupted cuts (cross-holes, slots) or when the machine lacks rigidity. It offers the highest impact toughness for stainless steel.

Q: What is the benefit of the DM chipbreaker?

A: The DM chipbreaker is an "all-rounder" for medium machining. It provides a sharp cutting edge while maintaining strength, ensuring stable chip breaking even at varying depths of cut.

Q: Can I use this for carbon steel?

A: While it can cut steel, it is not optimized for it. For steel (ISO P), the YBC series (e.g., YBC251) will provide significantly longer tool life and better economy.

Troubleshooting Tip: Excessive built-up edge? Increase cutting speed (Vc). Edge chipping? Switch to YBM351 or reduce feed rate (fn).

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.
