PRODUCT FAQ

What grit is the Cubitron 3 flap disc, and what is it best used for?

This is a 60+ grit disc, which makes it ideal for aggressive grinding and material removal on steel, stainless steel, and other metals. It's perfect when you need fast stock removal with excellent edge life.
Will this disc fit my angle grinder, and how do I attach it?

Yes! The T27 flat quick change design with 5/8 in-11 thread fits standard angle grinders with quick change systems. You simply screw it onto your grinder's backing pad—no tools needed—making changes fast and easy between jobs.
How many discs come in each case, and what's the disc diameter?

Each case contains 5 flap discs. They're 7 inches in diameter, which is the most common size for 4.5 to 5 inch angle grinders, giving you great versatility for both detailed work and larger surface areas.

Premium Performance 3M Cubitron 3 Flap Disc 1169F

The 3M Cubitron 3 Flap Disc 1169F represents an advanced abrasive solution engineered for demanding industrial applications. This long-lasting, versatile disc combines the inherent advantages of flap disc technology—including exceptional conformability and user-friendly operation—with a notably reduced risk of surface gouging. Built with a resilient polyester backing, this disc is specifically designed to deliver superior performance on carbon steel substrates.

This flap disc demonstrates exceptional material removal efficiency, achieving up to 49% greater total material removal compared to the 3M Cubitron II Flap Disc 969F in the 40+ grade category, and up to 66% more material removal when compared to the 3M Flap Disc 769F 40+ grade. These performance metrics make it an excellent choice for medium to high-pressure grinding operations that demand both speed and durability.

Advanced Grain Technology

The 3M Cubitron 3 Flap Disc 1169F features an innovative proprietary design incorporating 3M Precision-Shaped Grain that has been re-engineered with curved sides. This sophisticated engineering allows the abrasive grain to continually fracture into progressively sharper points, enabling the disc to slice cleanly through metal surfaces. Unlike conventional abrasive materials that tend to plow through substrates, this fracturing action promotes exceptional longevity and maintains a high cutting rate throughout the life of the disc.

Recommended Applications

Weld grinding
Light grinding operations
Beveling work
Deburring
Blending and finishing
Surface preparation
Scale removal
Weld spatter removal
Work on edges and contours

Efficiency Advantage

A notable benefit of the 3M Cubitron 3 Flap Disc 1169F is its ability to consolidate grinding and finishing operations into a single step, potentially eliminating the need for abrasive changes. Under typical working conditions, this disc produces a surface finish comparable to a fiber disc of one grade finer than its own designation. While fiber discs may cut at faster initial rates, the 1169F can significantly streamline workflow by reducing equipment changeovers and associated downtime.
