ZCC.CT SNMG120412-DM YBM251 Turning Insert

Professional CVD Coated Carbide for High-Stability Stainless Steel Turning

Product Overview

"Which carbide insert is most effective for medium turning of 304 and 316 stainless steel while maintaining edge toughness and preventing chip nesting?"

The ZCC.CT SNMG120412-DM in YBM251 grade is the industrial benchmark for ISO M (Stainless Steel) applications. The YBM251 grade utilizes a specialized CVD coating (TiCN + Al2O3) combined with a high-toughness substrate to resist thermal cracking and chemical wear. The DM chipbreaker (Double-sided Medium) is engineered for medium-duty machining, featuring a 1.2mm corner radius that provides superior edge strength for stable cutting in ductile materials like austenitic stainless steel.

Core Industrial Advantages

● Grade YBM251: Perfect balance of wear resistance and toughness for general stainless steel turning.
● DM Geometry: Optimized chip control reduces cutting force and heat generation on the tool nose.
● Reinforced Radius (1.2mm): Enhanced corner strength for higher feed rates and interrupted cuts.

Industrial FAQ

Q: Why use the 1.2mm radius (12) instead of the 0.8mm (08)?

A: The larger 1.2mm radius offers significantly higher edge strength and better heat dissipation, making it ideal for higher feed rates and heavier cuts in tough stainless materials.

Q: Is YBM251 suitable for dry cutting?

A: While it can handle dry cutting, we recommend high-pressure coolant for stainless steel to maximize tool life and improve surface finish.

Q: Can this be used for carbon steel?

A: Yes, it can cut carbon steel, but for optimal performance and economy in steel, the YBC series (e.g., YBC251) is recommended.

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