PRODUCT FAQ

What grit is this flap disc and what type of materials can it handle?

This is a 60+ grit flap disc, which makes it ideal for aggressive grinding and stock removal on steel, stainless steel, and other metal surfaces. The higher grit designation provides good material removal rates while still delivering a quality finish.
What does the T29 Quick Change system mean, and is it compatible with standard grinders?

T29 Quick Change refers to the conical backing pad design that allows you to swap discs quickly without tools. It's compatible with most standard angle grinders equipped with a Quick Change adapter or compatible backing pad, making your job much more efficient.
How many discs come in each case, and what size is this flap disc?

Each case contains 10 flap discs. The disc is 4 inches in diameter with a 3/8-inch thickness, making it a versatile size for both detail work and larger surface grinding applications on your angle grinder.

Premium Performance 3M Cubitron 3 Flap Disc 1169F

The 3M Cubitron 3 Flap Disc 1169F represents a significant advancement in abrasive disc technology, offering exceptional durability and versatility for demanding grinding applications. This innovative flap disc combines the inherent advantages of traditional flap disc design—including superior conformability, user-friendly operation, and minimized risk of surface gouging—with cutting-edge material removal capabilities. Through rigorous engineering and performance testing, this disc demonstrates remarkable efficiency, removing up to 49% more total material compared to the 3M Cubitron II Flap Disc 969F in the 40+ grade range, and up to 66% more material than the 3M Flap Disc 769F 40+ grade, making it an excellent choice for businesses seeking to maximize productivity.

Advanced Grain Technology

At the heart of the 3M Cubitron 3 Flap Disc 1169F lies the proprietary 3M Precision-Shaped Grain technology, which has been meticulously re-engineered with curved sides to optimize cutting performance. Unlike conventional abrasive materials that rely on plowing action to remove material, the precision-shaped grains continuously fracture into fresh, razor-sharp cutting points that cleanly slice through metal substrates. This self-sharpening characteristic enables the disc to maintain exceptional cut-rates throughout its operational lifespan while significantly extending overall disc longevity.

Construction and Durability

The 3M Cubitron 3 Flap Disc 1169F features a robust polyester backing designed to withstand the rigors of medium to high-pressure grinding applications. This durable construction ensures consistent performance across prolonged use while maintaining structural integrity during demanding metalworking tasks.

Recommended Applications

Weld grinding and preparation
Light grinding operations
Beveling and edge work
Deburring and finishing
Blending and surface preparation
Scale and oxidation removal
Weld spatter removal
Contour and edge contouring work

Operational Efficiency Benefits

The 3M Cubitron 3 Flap Disc 1169F offers a distinct operational advantage by generating surface finishes that are typically one grade finer than equivalent fiber discs of the same grade specification. This characteristic enables operators to combine grinding and finishing operations into a single step under normal working conditions, effectively eliminating the need for mid-job disc changes. While fiber discs may achieve slightly faster initial cutting speeds, the 1169F's capability to reduce operational steps results in substantial time savings and improved workflow efficiency for professional applications.
