SALI 100 Pack Cut Off Wheel - 4-1/2-inch x .047-inch x 7/8-inch Cutting Discs for Metal & Stainless Steel

High-performance cutting discs for metalwork

When you’re cutting metal, consistency and control matter. SALI's 100-pack of cut-off wheels is designed to deliver reliable, burr-free cuts across a range of metals, from mild steel to stainless steel. The 4-1/2-inch diameter and 7/8-inch arbor fit most common grinders, so you can go from setup to finished cut with minimal fuss. The thin wheel profile minimizes material loss and leaves a smoother edge as you progress along your project, helping you stay productive without sacrificing accuracy.

What makes these discs stand out

Each disc balances speed with durability. The wheel thickness sits around 0.045–0.047 inches, a design choice that reduces the amount of material that must be removed per pass while maintaining rigidity during aggressive cutting. A proprietary aluminum oxide grain is optimized for fast cutting action, enabling you to cut through metal more efficiently than thicker, less focused discs. The grain is paired with a double fiberglass mesh reinforcement, which adds strength and helps resist cracking under heat and vibration—an important factor on longer cuts.

• Size: 4-1/2-inch diameter, 7/8-inch arbor, ultra-thin profile (approximately 0.045–0.047 inches)
• Performance: fast, burr-free cutting suitable for metal and stainless steel projects

Real-world use cases and outcomes

In a busy workshop, these wheels glide through steel tubing, brackets, and sheet metal with a confident bite. The thin design helps you maneuver tight corners and finish a line with fewer passes, while the sturdy construction stands up to repeated use. Expect noticeable edge quality improvements and a clean cut with reduced post-processing needs in many fabrication tasks.

• Use cases: metal fabrication, automotive work, DIY metal projects, maintenance tasks
• Possible outcomes: quicker cuts, cleaner edges, longer wheel life, reduced burr formation
