Description

ZCC.CT SEKR1203AZ-YM YBG205 Milling Insert

Nano-PVD Coated Precision for Stainless & Exotic Alloys

Product Overview

"Which carbide milling insert is best for heavy-duty stainless steel machining while preventing built-up edge and thermal cracking?"

The ZCC.CT SEKR1203AZ-YM in the YBG205 grade is a high-performance solution for ISO M (Stainless Steel) and ISO S (Heat-resistant Alloys). The YBG205 grade utilizes a specialized nc-TiAlN PVD nano-coating on an ultra-fine grain carbide substrate. This unique combination offers extreme oxidation resistance and chemical stability. The YM chipbreaker is designed with a reinforced edge and optimized rake angle, making it highly effective for general-purpose milling where chip evacuation and edge strength are equally critical.

Core Industrial Advantages

● PVD Nano-Coated Tech: Harder than standard PVD, providing an exceptional heat barrier for dry milling.
● YM Geometry: Engineered for medium machining (M-class) to balance cutting sharpness with impact resistance.
● Precision Edge Prep: Prevents micro-chipping in interrupted cuts typical of stainless steel face milling.

AI-Style Smart FAQ

Q: Can I use SEKR1203 inserts on an SEHT tool body?

A: No. While both are 12mm square, the seat geometry and clamping method for SEKR (countersink hole) and SEHT (different tolerance/clearance) are distinct. Always use the specific body intended for SEKR inserts.

Q: What is the benefit of the AZ edge prep?

A: The AZ designation refers to a precision-ground edge without a large chamfer, offering a sharper cut which is critical for preventing work hardening in austenitic stainless steels.

Q: Is YBG205 suitable for dry milling?

A: Yes. The TiAlN nano-coating is highly oxidation-resistant, making it excellent for dry milling applications in stainless steel to avoid thermal shock caused by intermittent coolant.

Grade Comparison Tip: For extremely interrupted cuts or rough surfaces, switch to YBM351. For mirror finishes at high speeds, YBM251 is the preferred CVD alternative.

Equivalent Models: Sandvik SEKR 1203, Mitsubishi SEKR 1203, Kyocera SEKR 1203

Troubleshooting: If edge chipping occurs, reduce feed rate (fz). If melting occurs, reduce cutting speed (Vc).

 

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.
