Black Rock Cutting Disc Turbo 4.5"

Diameter: 4.5 inches (115 mm). Blade thickness: 0.2 inches. Bore sizes available: 9 mm, 22.23 mm, 25.4 mm, and 25.4–30 mm, allowing direct fit to many power tools without adapters.

It’s designed for versatility and can cut ferrous and non-ferrous metals, stainless steel, as well as plastic and wood, thanks to its high-grade fiberglass construction and premium aluminum oxide grain.

The disc is rated for a maximum speed of 13,230 RPM. Do not exceed this limit and always run the tool with the appropriate guard and safety precautions.

The turbo segments reduce resistance and heat buildup, enabling faster cuts, while the curved design helps maintain a smoother cutting action and better control across different materials.

Choose the correct bore size for your tool (9 mm, 22.23 mm, 25.4 mm, or 25.4–30 mm). Mount using standard flanges and keep the disc flat and tight. Ensure the tool is powered off during installation and always use the appropriate guard.

Always wear eye protection, gloves, hearing protection, and a face shield if needed. Inspect the disc for cracks or damage before use, use the guard, avoid side loading or twisting, and operate at or below the maximum RPM. Allow the disc to cool if it heats up excessively.

Cut with steady, even pressure and let the disc do the work. Avoid excessive feed rates that generate heat, use proper cooling if cutting tough materials, and store discs in a dry, clean area to prevent corrosion or damage.

Store in a dry, cool place away from direct sunlight or chemicals. Keep discs flat and avoid dropping them, which can cause micro-cracks that compromise performance.

The Black Rock Turbo 4.5" disc emphasizes extra-thick 0.2" blade for longevity, a turbo segment design for speed, and a curved profile for versatile cutting across metals, plastics, and wood. When evaluating alternatives on Fepy, consider blade thickness, bore compatibility, RPM rating, and turbo vs standard segment designs to match your material and tool requirements.

Use it for fast metal fabrication cuts (ferrous and non-ferrous), stainless steel portions, plastic edging, and woodworking tasks that require aggressive cutting with a durable blade. It’s well-suited for automotive work, metal fabrication, and general DIY metal/tech projects.
