PRODUCT FAQ

What grit level is this flap disc, and what type of work is it best for?

This disc comes in 40+ grit, which makes it ideal for aggressive grinding and material removal on metal surfaces. It's perfect for tasks like weld grinding, paint removal, and general deburring where you need fast stock removal.
Will this flap disc work with my standard angle grinder?

Yes! The T27 flat design with 5/8"-11 threading is the standard quick change connection, so it will fit most 4-1/2 inch angle grinders that have that same spindle size. Just double-check your grinder's specifications to be sure.
How many discs come in one case?

Each case contains 10 flap discs, giving you plenty of inventory for your projects without needing to reorder frequently.
What makes 3M Cubitron 3 better than other flap discs?

Cubitron 3 features advanced ceramic grain technology that stays sharper longer, cuts faster, and runs cooler than conventional abrasives. This means you'll spend less time grinding and more time being productive, plus you'll get longer life from each disc.
Is the quick change system easy to use?

Absolutely. The quick change system makes swapping discs fast and tool-free, so you can change out worn discs in seconds without any hassle or downtime on the job.

Premium Performance 3M Cubitron 3 Flap Disc 1169F

The 3M Cubitron 3 Flap Disc 1169F represents an advanced abrasive solution engineered to deliver exceptional durability and versatility across a wide range of grinding and finishing applications. This premium flap disc incorporates all the essential benefits traditionally associated with flap disc technology, including superior conformability to workpiece contours and user-friendly operation, while simultaneously reducing the likelihood of surface gouging that can compromise finished parts.

Built upon 3M's proprietary Precision-Shaped Grain technology—now featuring an innovative curved-side design—and reinforced with a robust polyester backing material, the 1169F achieves remarkable material removal efficiency. Performance testing demonstrates that this disc removes up to 49% more total material compared to the 3M Cubitron II Flap Disc 969F in the 40+ grit grade, and impressively outperforms the 3M Flap Disc 769F 40+ grade by approximately 66%. This enhanced performance makes it particularly well-suited for demanding medium to high-pressure grinding operations while also producing a refined surface finish suitable for secondary operations.

Key Technology Features

The re-engineered Precision-Shaped Grain design with curved edges represents a significant advancement in abrasive technology. Unlike conventional abrasive materials that tend to create plowing action through the workpiece material, these precision-engineered grains continuously fracture into progressively sharper micro-points. This self-sharpening action enables clean, efficient cutting through metal substrates while substantially extending disc life and maintaining consistent cutting performance throughout the product's operational lifespan.

Recommended Applications

Weld grinding operations
Light grinding tasks
Beveling and edge preparation
Deburring and edge finishing
Blending operations
General finishing work
Surface preparation and conditioning
Scale removal
Weld spatter removal
Work on edges and contoured surfaces

Operational Advantage

A notable benefit of the 1169F is its capability to perform combined grinding and finishing operations in a single step under normal working conditions. The disc produces a surface finish that typically matches or exceeds the quality of a conventional fiber disc one grit grade finer, effectively eliminating the need for intermediate abrasive changes. This integrated approach streamlines workflow efficiency, reduces tool changeover time, and ultimately contributes to improved productivity in professional grinding environments.
