PRODUCT FAQ
-
What grit is the Cubitron 3 Flap Disc 1169F, and what types of materials can it work on?
The 1169F comes in 80+ grit, which is ideal for medium-to-aggressive grinding and blending applications. It works great on steel, stainless steel, and other metal surfaces, making it perfect for general fabrication and finishing work.
-
What does the T29-Conical shape mean, and why would I choose it?
The T29-Conical shape features a conical backing pad that delivers consistent contact pressure across the disc surface. This design is excellent for curved or contoured surfaces because it provides better conformability and more uniform grinding results compared to flat designs.
-
How many discs come in each case, and what's the disc diameter?
Each case contains 5 flap discs. The disc is 7 inches in diameter with a 7/8 inch arbor hole, making it compatible with standard angle grinders and other power tools in that size range.
The 3M Cubitron 3 Flap Disc 1169F represents an advanced abrasive solution engineered to deliver exceptional longevity and versatility across a wide range of grinding and finishing applications. This sophisticated flap disc combines the inherent advantages of flap disc technology—including superior conformability to workpiece contours and user-friendly operation—with a thoughtfully designed construction that significantly reduces the potential for surface gouging and material damage during use.
At the core of this product's superior performance lies 3M's proprietary Precision-Shaped Grain technology, which has been meticulously re-engineered to incorporate curved grain edges. This innovative design promotes controlled fracturing during use, generating continuously sharp cutting points that efficiently slice through metallic substrates with precision. In contrast, conventional abrasive materials typically utilize a plowing action that generates excessive heat and material waste. The advanced grain fracturing mechanism employed in the Cubitron 3 formulation ensures extended disc lifespan while maintaining an impressively consistent cutting rate throughout the product's operational life.
Constructed with a durable polyester backing, the 3M Cubitron 3 Flap Disc 1169F demonstrates remarkable material removal efficiency. When applied to carbon steel surfaces, this disc removes up to 49% more total material compared to the 3M Cubitron II Flap Disc 969F in 40+ grade, and up to 66% more material than the 3M Flap Disc 769F 40+ grade. These performance metrics make it particularly well-suited for medium to high-pressure grinding operations where productivity and efficiency are paramount.
Recommended Applications- Weld grinding operations
- Light grinding tasks
- Beveling and edge preparation
- Deburring and edge smoothing
- Blending and surface finishing
- Finishing work
- Surface preparation and conditioning
- Scale and oxidation removal
- Weld spatter removal
- Work on contoured edges and irregular surfaces
A significant operational benefit of the 3M Cubitron 3 Flap Disc 1169F lies in its ability to perform both grinding and finishing tasks sequentially without requiring abrasive disc changes. Under normal operating conditions, this flap disc produces a surface finish comparable to that achieved by a fiber disc of one grade finer rating. While fiber discs may offer marginally faster cutting speeds, the Cubitron 3's dual-function capability effectively consolidates multiple steps into a single operation, thereby reducing production time and minimizing costly disc changeover procedures.
