PRODUCT FAQ

What grit is the 3M Cubitron 3 Flap Disc 1169F?

The 1169F features a 40+ grit, which makes it ideal for aggressive stock removal and grinding on metal surfaces. It's designed for faster material removal while still maintaining a good finish.
What is the diameter and hole size of this flap disc?

This flap disc measures 4 inches in diameter with a 5/8-inch hole, making it compatible with most standard angle grinders and similar tools.
How many discs come in each case?

Each case contains 10 flap discs, giving you plenty of product for your project or job site needs.
What does the T29 conical design mean?

The T29 conical backing pad means the flaps are arranged in a cone shape that points slightly away from the work surface. This design improves air circulation, reduces heat buildup, and allows for better control during grinding operations.
What are the main advantages of using Cubitron 3 compared to other flap discs?

Cubitron 3 features 3M's advanced ceramic grain technology, which fractures as it dulls to continuously expose sharp edges. This means longer tool life, less downtime for disc changes, and reduced operator fatigue compared to traditional abrasives—saving you time and money on the job.

Premium Performance 3M Cubitron 3 Flap Disc 1169F

The 3M Cubitron 3 Flap Disc 1169F represents a sophisticated advancement in abrasive disc technology, engineered to deliver exceptional durability and versatility across a wide spectrum of grinding applications. This high-performance flap disc incorporates all the inherent benefits characteristic of quality flap disc design, including superior conformability to work surfaces, user-friendly operation, and a notably reduced risk of workpiece gouging or damage during use.

Advanced Grain Technology

At the heart of this product lies 3M's proprietary Precision-Shaped Grain technology, which has been meticulously re-engineered with curved sides to optimize cutting efficiency. This innovative grain design continually fractures during use, generating continuously sharp cutting edges that slice through metal substrates with precision. This represents a substantial improvement over conventional abrasive products, which typically employ a plowing action that generates excess heat and reduces tool longevity. The curved-side grain structure enables the 1169F to maintain superior cutting rates throughout the disc's operational life, making it an economically efficient choice for demanding industrial applications.

Performance Advantages

When compared to previous generation products, the 3M Cubitron 3 Flap Disc 1169F demonstrates remarkable performance gains. It removes up to 49% more total material than the 3M Cubitron II Flap Disc 969F in the 40+ grade designation, and up to 66% more material than the 3M Flap Disc 769F 40+ grade. Backed by a durable polyester construction, this disc excels in medium to high-pressure grinding scenarios while simultaneously producing a refined surface finish.

Recommended Applications

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

Efficiency Tip

A significant advantage of the 3M Cubitron 3 Flap Disc 1169F is its ability to perform both grinding and finishing operations in a single step under normal working conditions. The disc produces a finish quality approximately one grade finer than a comparable fiber disc of identical grit rating. While traditional fiber discs may offer slightly faster initial cutting rates, the 1169F's capability to eliminate the need for disc changes and additional finishing steps can result in substantial time savings and improved operational efficiency across your workflow.
