PRODUCT FAQ
-
What materials can I use the 3M™ Cubitron™ 3 Flap Disc 1169F on?
You can use this flap disc on a wide range of metals, including mild steel and stainless steel. It’s great for grinding, blending, and finishing tasks!
-
What does “40+” mean in the product name?
“40+” refers to the abrasive grit size. It works like a traditional 40 grit disc but with extra-long life thanks to our advanced Precision-Shaped Grain technology.
-
Can I use this flap disc with any angle grinder?
Yes! As long as your angle grinder accepts a flat (Type 27) disc sized at 4-1/2 inches with a 7/8 inch center hole, it will fit perfectly.
-
How long does one disk typically last compared to other brands?
Great question! The Cubitron™ 3 Flap Disc lasts significantly longer than conventional ceramic or alumina zirconia discs because of its sharp and durable ceramic grains. That means fewer changeouts and more work done per disc!
-
What are some safety tips when using this flap disc?
Always wear proper PPE—eye protection, gloves, hearing protection—and make sure you’re using the correct speed setting recommended for both your tool and the disc. Stay safe out there!
The 3M™ Cubitron™ 3 Flap Disc 1169F is engineered to deliver exceptional performance and longevity, making it an ideal choice for demanding metalworking applications. This versatile abrasive disc combines the flexibility and user-friendly design you expect from a flap disc, while minimizing the risk of gouging your workpiece. Enhanced with 3M’s latest Precision-Shaped Grain technology—now featuring a re-engineered design with curved sides—this disc offers superior cutting efficiency and durability. The robust polyester backing ensures reliable performance, especially when working with carbon steel.
When compared to previous generations, the 3M™ Cubitron™ 3 Flap Disc 1169F stands out for its remarkable material removal rates. It removes up to 49% more material than the 3M™ Cubitron™ II Flap Disc 969F 40+ grade, and up to 66% more than the 3M™ Flap Disc 769F 40+ grade. This makes it particularly well-suited for medium to high-pressure tasks such as beveling, weld grinding, deburring, and working on edges and contours. Additionally, the disc leaves a refined finish, making it an excellent choice for blending and surface preparation tasks.
The secret behind the disc’s outstanding performance lies in its proprietary 3M Precision-Shaped Grain, which is now re-engineered with a unique curved sides design. Unlike conventional abrasives that tend to plow through metal, these grains continually fracture into sharp, fresh points that slice cleanly through the substrate. This self-sharpening action not only extends the life of the disc but also maintains a consistently high cut-rate throughout its use.
Key Applications- Weld grinding
- Light grinding
- Beveling
- Deburring
- Blending
- Finishing
- Surface preparation
- Scale removal
- Weld spatter removal
- Working on edges and contours
In many situations, the 3M™ Cubitron™ 3 Flap Disc 1169F allows you to both grind and finish in a single step, eliminating the need to switch abrasives. Under typical conditions, this flap disc produces a finish that is one grade finer than a fiber disc of the same grade. While fiber discs may offer a faster initial cut, the 1169F can streamline your workflow by reducing the number of steps and disc changes required, ultimately saving you valuable time and effort.
