ZCC.CT SPCW1204EDR YBG102 Carbide Milling Insert (Imperial Equivalent: SPCW43EDR)
1. Product Overview
Which indexable milling insert delivers peak metal removal rates and ultra-clean surface finishes when face milling aluminum, non-ferrous metals, and heat-resistant alloys?
The ZCC.CT SPCW1204EDR YBG102 (ANSI: SPCW43EDR) is a high-precision, 90° square positive indexable milling insert engineered for high-speed face milling, shoulder milling, and chamfering operations. Built with ZCC.CT’s advanced YBG102 Grade—a micro-grain carbide substrate coated with an ultra-smooth nano-PVD TiAlN structure—this insert features an exceptionally razor-sharp cutting edge combined with a polished rake face face geometry. The EDR Corner Chamfer Geometry reduces cutting force, prevents edge buildup (BUE), and provides outstanding thermal stability across high-speed aluminum alloy (6061/7075), copper, and finishing steel applications.
2. Key Features
- YBG102 Nano-PVD Coating: Ultra-fine PVD TiAlN coating featuring an extremely smooth surface finish to prevent chip welding, edge build-up, and localized adhesion when machining non-ferrous metals.
- Precision EDR Corner Chamfer Geometry: Rounded corner chamfer edge prep design that distributes cutting loads evenly, strengthening the corner against thermal chipping during high-speed face milling.
- Positive 11° Clearance Angle (P-Style): Significantly reduces flank wear friction and cuts cutting forces, eliminating tool deflection and chatter on thin-walled structural workpieces.
- Precision-Ground Perimeter: Tight tolerance manufacturing ensures accurate radial and axial runout control across multi-insert milling cutter heads.
- Dual ISO / ANSI Standard Specification: Fully standard 12.7mm (1/2") inscribed circle profile compatible with standard SPCW indexable milling cutters worldwide.
