SHINTE Machinery is a professional and reliable manufacturer and supplier of high-performance TiAlN Coating Steel Shear Blades with Smooth Surface and Hole Diameter in China. We specialize in precision PVD-coated shearing solutions for the metallurgical, steel service centers, sheet metal fabrication, stainless steel processing, and high-speed cutting industries worldwide. Established in 1999, Shinite Machinery Co., Ltd. has over 25 years of expertise in industrial blades and cutting tools.
We supply a complete range of industrial shear blades with advanced TiAlN coating, optimized for clean, high-speed cutting of steel sheets, coils, and plates. Explore our full range at Shear Blades & Knives and Mechanical Knife, including:
Our shear blades are made from high-grade alloy tool steels (D2, SKD11, Cr12MoV, H13, H13K, Hermanite alloy steel, and proprietary HMB/HMK developed by Shinite) and then coated with high-performance TiAlN (Titanium Aluminum Nitride) via PVD technology. This coating delivers exceptional results when cutting:
The TiAlN coating significantly increases surface hardness (up to 35 GPa), provides excellent oxidation resistance up to 800–900°C, reduces friction, and forms a protective aluminum oxide layer during cutting for superior wear resistance and longer blade life. For more technical details, visit our Production Process page.
We combine precise vacuum heat treatment with multi-layer TiAlN PVD coating processes under strict temperature and thickness control. This results in optimal substrate hardness (HRC 58–62), superior toughness, outstanding thermal stability, low coefficient of friction, and exceptional edge retention — ideal for high-speed shearing operations while maintaining a smooth surface finish. Shinite’s independent R&D ensures continuous innovation in coating and heat treatment.
Every TiAlN Coating Steel Shear Blade is precision-ground using advanced CNC equipment, high-precision surface grinders, and polishing machines to achieve an ultra-smooth surface (Ra 0.1–0.4μm). We strictly control hole diameter tolerance, mounting hole positions, and edge geometry. Full customization includes:

We implement a comprehensive quality system from raw material through heat treatment, precision grinding, TiAlN coating deposition, to final inspection. Each blade undergoes hardness testing, coating thickness measurement, adhesion testing, surface smoothness verification, hole diameter inspection, and trial cutting. This guarantees zero defects, perfect edge sharpness, smooth surface, precise hole diameters, and reliable high-performance in your shearing machines. View our quality commitments at Certificates.
Our TiAlN Coating Steel Shear Blades with Smooth Surface and Hole Diameter are available in various structures, including straight strip-type blades with accurately machined mounting holes, laminated multi-piece designs, and heavy-duty one-piece guillotine knives. They are specifically engineered for high-speed, high-volume steel sheet and coil processing lines. Browse all shear blade solutions at Shearing Machine Blades.
High-performance options include:
Whether you need standard replacement blades or fully custom TiAlN coated shear blades with exact hole diameters and mirror-smooth surfaces, we deliver solutions that reduce burrs, minimize built-up edge, extend service life up to several times longer than uncoated blades, and lower your overall tooling costs.
