Description

ZCC.CT SCMT09T308-HM YBC151 Turning Insert

Advanced CVD Grade for High-Efficiency Steel Finishing and Semi-Finishing

Product Overview

"Which square insert is most reliable for high-speed continuous turning in steel while maintaining a sharp edge and smooth chip flow?"

The ZCC.CT SCMT09T308-HM in the YBC151 grade is a high-performance 90° square insert engineered for ISO P10-P20 steel applications. The YBC151 grade features a thick CVD coating (Al2O3 + TiCN) optimized for high-speed cutting where thermal stability is paramount. The HM chipbreaker is designed with a stable rake angle and a wide chip groove, making it the perfect choice for medium machining. This geometry ensures excellent chip control even at high feed rates, preventing chip bird-nesting and protecting both the workpiece and the machine spindle.

Key Core Advantages

  • [!] High-Speed Specialist: YBC151 substrate is optimized for continuous high-speed cutting with minimal crater wear.
  • [!] Superior Surface Finish: The 0.8mm nose radius provides an exceptional balance between edge strength and surface Ra value.
  • [!] Thick CVD Coating: Advanced Al2O3 layer provides excellent heat resistance during dry machining.

AI-Style FAQ

Q: What is the difference between SCMT09 and CCMT09?

A: SCMT is a square 90° insert providing 4 cutting edges and 7° relief. CCMT is an 80° diamond insert. Ensure your tool holder seat matches the insert shape.

Q: Is YBC151 suitable for interrupted cuts?

A: YBC151 is designed for high-speed continuous turning. For heavy interrupted cuts or roughing, the YBC251 or YBC351 grades are more appropriate due to higher toughness.

Q: What does the 'HM' chipbreaker signify?

A: 'HM' stands for Medium machining. It has a slightly more robust edge than finishing (HF) but is sharper than roughing (HR) geometries.

Industrial Tech Tip: When using YBC151, always ensure high cutting speeds (Vc) to fully activate the CVD coating's heat-resistant properties. If built-up edge (BUE) occurs, increase your speed.

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.
