Product Detailed Description
The LNGX120508ER-F is a high-performance double-sided milling insert engineered for precision 90° square shoulder milling, face milling, and interrupted cutting across carbon steel, alloy steel, and stainless steel. Featuring a 12mm cutting edge length, 0.8mm corner radius, enhanced chip-breaker design, and industrial-grade M8330F PVD coating, this insert delivers exceptional wear resistance, stable chip evacuation, and consistent surface finish (Ra ≤1.6μm) - making it ideal for CNC machining centers in automotive manufacturing, mechanical engineering, and mold production. Designed to fit standard SLN12 series square shoulder mill holders, it offers reliable compatibility and cost-effective solutions for medium to heavy-duty applications.

2. Core Design & Material Advantages
- Double-Sided Helical Edge Geometry: Features 4 usable cutting edges (2 per side) to maximize tool life and reduce per-part machining costs by 30% vs. single-sided inserts. The helical edge design distributes cutting force evenly, reducing vibration by 20% and minimizing workpiece deformation.
- M8330F Enhanced PVD Coating: Industrial-grade physical vapor deposition (PVD) coating with a multi-layer TiAlN-TiC structure delivers exceptional wear resistance, oxidation resistance up to 880ºC, and low friction coefficient. This coating prevents built-up edge (BUE) and extends tool life by 2-3 times in stainless steel (304/316) machining.
- Micrograin Carbide Base: Constructed from fine-grained WC-Co carbide (ISO grade P30-P50) with 10% Co content, balancing hardness (HRA 92.5) and toughness to withstand interrupted cuts in cast iron (HT200/QT450) and shock loads in alloy steel.
- Enhanced Chip-Breaker (E-Series): Integral U-groove chip-breaker with enlarged flute volume accelerates chip evacuation, even at high feed rates (0.10-0.20 mm/tooth). The design prevents chip clogging and re-cutting, reducing heat buildup in deep cuts (max depth of cut: 10mm).
- Precision Honed Edge: 0.01-0.02mm honed edge radius enhances edge strength, preventing micro-chipping in high-speed machining and improving surface finish consistency.

- 3. Application & Cutting Parameters
-
- Carbon steel (S235, 45#), alloy steel (40Cr, 20CrMnTi)
- Austenitic stainless steel (304, 316, 316L), martensitic stainless steel (410)
- Cast iron (HT200, QT450), ductile iron (GJS400)
- Typical Machining Scenarios:
- Square shoulder milling of 40Cr steel automotive transmission cases
- Face milling of 304 stainless steel chemical equipment brackets
- Interrupted cutting of QT450 cast iron engine blocks
- Precision contour milling of P20 mold steel components
