ZCC.CT SNMG120416-15 YBC251 Turning Insert

The Powerhouse for Heavy Roughing and Interrupted Steel Cuts

Product Overview

"Which carbide insert is best for heavy roughing of steel shafts with interrupted cuts while maintaining long tool life?"

The ZCC.CT SNMG120416-15 in YBC251 grade is a high-performance solution for ISO P (Steel) machining. Featuring a robust 1.6mm corner radius, this insert is built for strength. The YBC251 grade utilizes a thick CVD coating (TiCN + Al2O3) to provide an exceptional thermal barrier. Combined with the -15 chipbreaker (specifically designed for medium-heavy roughing), it offers unmatched edge stability and chip control even when the depth of cut is high or the machining condition is unstable.

Core Industrial Advantages

● Extreme Edge Strength: The 1.6mm radius (16) handles high impact and heavy feed rates without chipping.
● -15 Roughing Geometry: Aggressive chip-breaking for large chips in heavy steel turning.
● YBC251 Grade: The versatile "General Purpose" steel grade that balances wear and impact resistance.

Industrial FAQ

Q: Why use the -15 chipbreaker?

A: The -15 chipbreaker is specifically designed with a reinforced cutting edge for roughing. It handles heavy chips and prevents edge collapse under high pressure.

Q: Can I use this for stainless steel?

A: While it can cut stainless, the YBM series is better suited for ISO M materials. YBC251 is optimized for ISO P (Steel).

Q: When should I choose YBC351 instead?

A: Switch to YBC351 if you encounter extreme interruptions or if the machine lacks rigidity and you need maximum impact resistance.

Troubleshooting: Plastic deformation? Increase speed (Vc). Edge Chipping? Decrease feed (fn) or move to YBC351.

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.
