Steel Demon 4-1/2 In. D X 5/8 In. Zirconia Speed Hub Thread Arbor Flap Disc 40 Grit 1 Pk

Introducing the Diablo Steel Demon flap disc, engineered for demanding metalwork on angle grinders. The 4-1/2 in. diameter with a 5/8 in.-11 hub uses a zirconium-infused abrasive blend to accelerate material removal, delivering faster stock removal than traditional grinding wheels. The Type 29 grinding profile works with flat and contoured surfaces, while the flexible flap design provides a cushioned, forgiving cut and a smoother finish.

How It Helps You: This flap disc speeds up jobs by combining grinding and finishing in a single step, reducing downtime and tool changes. The durable abrasive composition stays cool under heavy use, helping maintain workpiece integrity and prolonging disc life.

• Zirconium flap disc delivers high-speed metal removal with extended life, ideal for demanding steel fabrication
• Type 29 profile provides aggressive stock removal on flat and curved surfaces while maintaining control
• 4-1/2 in diameter with 5/8 in-11 hub fits most angle grinders for quick, secure mounting
• Flexible flap construction cushions grinding, reduces heat buildup, and minimizes gouging for a smoother finish
• 40 grit rating balances rapid material removal with a quality finish for metalworking projects

Why this Flap Disc Stands Out: It combines speed, control, and durability in a single metalworking tool, making it a go-to choice for professional grinders. With its secure hub and rugged zirconium blend, you’ll minimize downtime, reduce heat, and achieve a smooth, uniform finish on stainless and carbon steels. Built to last through demanding jobs, this flap disc delivers consistent performance from start to finish.
