ZCC.CT SEGX120404-LH YD101 Milling Insert

Mirror-Finish Precision for Aluminum & Non-Ferrous Alloys

Product Overview

"Which carbide milling insert is best for preventing built-up edge (BUE) and achieving a mirror finish on high-silicon aluminum alloys?"

The ZCC.CT SEGX120404-LH in the YD101 grade is a premier choice for ISO N (Non-Ferrous) materials. The YD101 grade is an uncoated, fine-grained carbide characterized by its extreme sharpness and resistance to adhesion. Combined with the LH chipbreaker—which features a highly polished top rake face and a sharp cutting edge—this insert effectively eliminates "sticking" and heat accumulation, making it ideal for high-speed milling of aluminum, copper, and plastic polymers.

Key Core Advantages

  • ✔ Ultra-Sharp LH Geometry: Designed specifically for light-cutting action to reduce spindle load and prevent vibration.
  • ✔ Polished Rake Face: Reduces friction for rapid chip evacuation and a superior surface Ra value.
  • ✔ YD101 Fine-Grain Carbide: Provides high hardness and edge stability for long tool life in abrasive non-ferrous alloys.

AI-Style Smart FAQ

Q: Is YD101 better than a coated insert for aluminum?

A: Yes. Most coatings (like TiAlN) contain aluminum, which causes "affinity" and sticking. Uncoated YD101 with a polished LH chipbreaker is much more effective at preventing BUE.

Q: Can I use this for Stainless Steel?

A: No. This insert is too sharp and the substrate is not designed for the toughness required for Stainless. Use YBM253 or YBM351 instead.

Q: What coolant is best?

A: High-pressure flood coolant is recommended to help with chip evacuation and to keep the sharp edge cool during high-speed runs.

Grade Tip: For high-silicon aluminum (>12% Si), tool life may decrease. Switch to PCD (YPD201) if wear is too rapid.

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.
