🔥 Product Highlights
- Aggressive Stock Removal: P36 coarse grit silicon carbide grains cut fast through heavy rust, old paint, weld slag, and oxidation, outperforming standard grinding wheels
- Universal Fit: Standard Ø115×22mm bore, compatible with most 4.5-inch angle grinders for quick, easy installation
- Safety First: Rated for a maximum linear speed of 80m/s, reinforced fiber backing prevents shattering and wobble at high RPM
- Longer Service Life: Spiral abrasive pattern enhances heat dissipation and reduces clogging, delivering up to 30% longer life than conventional discs
- Multi-Use Performance: Ideal for metal rust removal, weld cleaning, stone/concrete shaping, and paint stripping for both industrial and DIY applications
Product Specifications
Parameter Details Product Name Silicon Carbide Heavy-Duty Abrasive Disc Grit P36 (Coarse Grinding) Outer Diameter 115mm (4.5 inch) Bore Size 22mm Abrasive Material Black Silicon Carbide (SiC) Backing Material High-Strength Resin Fiber Board Max Linear Speed 80m/s Compatible Tools 4.5-inch Angle Grinders (10,000-13,000 RPM) Applications Metal Rust/Paint Removal, Weld Grinding, Stone/Concrete Edging, Casting Deburring ✨ Core Advantages
1. Fast & Efficient Coarse Grinding
Made with high-hardness silicon carbide grains, the P36 grit disc delivers sharp, aggressive cutting power. It removes stubborn rust, thick paint, and weld spatter in a single pass, eliminating the need for repeated work and boosting productivity.2. Spiral Abrasive Design for Cooler, Smoother Operation
The unique spiral pattern improves airflow during grinding, lowering operating temperatures to prevent grain softening and premature wear. It also reduces debris buildup, preventing slipping or "polishing" and ensuring consistent performance.3. Reinforced Fiber Backing for Safety & Durability
The high-strength resin fiber backing undergoes strict dynamic balance testing, ensuring stable operation without vibration or shattering at high speeds. Strong bonding between the backing and abrasive layer prevents grain loss for extended use.4. Versatile for All Scenarios
- Industrial: Steel structure rust removal, weld cleaning, casting deburring, metal surface preparation
- Construction: Stone/concrete edging, wall paint stripping, metal door/window restoration
- DIY Projects: Wrought iron furniture refinishing, tool sharpening, custom metalwork shaping
