Black & Decker Steel Cutting Disc, 4-1/2", Thin Cut & Reinforced Safety Layers

This disc is designed for cutting steel rod and sheet with a narrow kerf for cleaner, cooler cuts. It emphasizes reliability and consistent performance in everyday metalworking tasks.

Thin Cut refers to a slim wheel profile that reduces burr formation and sparks, allowing for smoother, faster cuts with less material waste.

Reinforced safety layers are fiberglass laminates that add structural safety at grinder speeds, helping to prevent wheel shattering and improve overall safety during use.

This disc fits 115 mm angle grinders with standard bores, making it compatible with common 4-1/2 inch grinders used in home and professional workshops.

Ensure the grinder is powered off and unplugged, remove the old disc, align the disc with the spindle and guard as instructed by your grinder’s manual, securely fasten with the appropriate nut, and spin test before cutting.

Use steady, moderate feed pressure and a straight cutting motion. Let the disc do the work, avoid forcing the tool, and allow cooling periods to prevent overheating.

Wear safety glasses or a face shield, hearing protection, gloves, and sturdy clothing. A dust mask or respirator is recommended for dusty environments.

Yes, it’s suitable for cutting steel rod and sheet. For thicker or highly reinforced materials, use multiple passes with controlled feed and allow cooling between cuts.

Disc life depends on material type, cut depth, feed rate, and operating conditions. Cooler, steady cuts with proper guard and cooling typically yield longer life.

Store in a dry, clean place away from moisture and oils. Keep the disc in its original packaging or a protected container to prevent damage, and handle with care to avoid chipping the edge.
