Professional 4.5 Inch Angle Grinder Grinding Discs China Factory Suppliers
Elevate your metalworking precision with our professional-grade OEM 4.5-inch Angle Grinder Grinding Discs. Specifically engineered for aggressive stock removal, these resin-bonded wheels feature a high-performance Brown Aluminum Oxide grain structure and R-grade hardness, ensuring superior durability and a consistent cut rate across all types of ferrous metals and stainless steel.
Designed to meet stringent ANSI and EN standards, our Type 27 depressed center wheels provide maximum versatility, allowing operators to work at constrained angles from 0 to 45 degrees. With reinforced fiberglass mesh and a self-sharpening grain structure, these discs minimize vibration while maximizing efficiency in tank fabrication, power plant maintenance, and industrial welding shops.

Frequently Asked Questions
Type 41 is a flat snagging wheel with a straight profile, ideal for high-speed die grinders to remove excess metal. Type 27 is a depressed center wheel, which allows for a wider range of grinding angles (0-45 degrees) and provides better clearance for the operator.
For the most aggressive stock removal and deburring of heavy welds, 24 grit is recommended. For a smoother finish or lighter grinding, 30 or 46 grit are better options.
Yes, we offer specific Grinding Discs for Inox (Stainless Steel) that use specialized aluminum oxide grains to prevent contamination and provide a clean, efficient cut on stainless materials.
Our premium grinding wheels are manufactured to meet both ANSI and EN standards, and are certified under MPA, EN12413, and ISO9001 to ensure maximum operator safety.
Absolutely. We provide OEM services with a variety of thickness options including 4mm, 6mm, 6.5mm, 7mm, and 8mm to suit different industrial applications.
The maximum operating speed for our grinding discs is 80m/s (approximately 13,300 RPM). Always ensure your angle grinder does not exceed this speed for safety.
