Advanced Features & Professional Benefits

SC/AO 24-Grit Abrasive Blend

• The wheel combines the fast material removal of silicon carbide with the toughness of aluminum oxide, specifically tuned for cutting ductile and cast iron. This blend enables rapid, free-cutting action and lasts longer than wheels made with either abrasive alone.

Universal Arbor Design (20mm/1”)

• Norton’s patented universal arbor ensures perfect fit and stability on both 20mm and 1" spindles—a unique solution that eliminates the need for extra bushings and streamlines inventory management for fleet operators, contractors, and rental businesses.

High-Speed, Durable Construction

• Designed for high-cycle, high-torque saws up to 5,400 RPM. The wheel is reinforced to reduce breakage during tough jobs, withstand side-loading, and maintain a straight cutting path under aggressive use.

Gemini Ductile: Built for Pipe, Iron, and Utility Work

• Delivers clean, efficient cuts in:

  • Ductile and cast iron pipe (cement or concrete-lined)

  • Water mains, sewer lines, heavy-duty PVC and plastic

  • Structural steel, angle iron, and more

• Perfect for city utilities, emergency repairs, and industrial fabrication

• Provides extended life and lower cost per cut compared to competitor wheels and even outperforms many diamond blades in cost-sensitive applications.

Application Scenarios

• Water Main and Sewer Projects: Far exceeds standard blades for both initial and finishing cuts on cement-lined ductile iron and heavy-duty mains.

• Municipal Utility Work: Fast setup and reliable, consistent performance for pipe repairs, road openings, or infrastructure tie-ins.

• General Metal Fabrication: Versatile enough for structural work, angle iron, fencing, and steel sectioning in shops or on-site.

• Rental Fleets and Emergency Kits: Universal arbor and durability make this wheel a staple for public works, rental, and first-response equipment.

Industry Comparison Table

Hands-On Performance & User Testimonials

• “Most of our crew won’t use anything else for ductile mains—fast, fewer wheel swaps, and it cuts even concrete linings cleanly.”

• “Universal arbor is a game-changer for the city team—no more tracking bushings for our mix of saws.”

• “Diamond is nice, but when cost matters, Gemini Ductile gets the work done, lasts longer than generic blades, and never splinters or kicks back when scoring.”.

Best Practices and Safety

• Always check for wheel cracks or damage before mounting.

• Match wheel to correct RPM of your saw—never exceed manufacturer speed specs.

• Wear proper PPE (face shield, gloves, and sleeves); cut in a well-ventilated area.

• Store wheels on edge or flat, away from moisture, sun, and excessive heat.
