PRODUCT FAQ

What grit is this flap disc and what is it best used for?

This is an 80+ grit disc, which makes it ideal for aggressive grinding, blending, and stock removal on steel, stainless steel, and other metals. It's perfect when you need fast material removal with a good finish.
What does the T29 conical design mean?

The T29 conical design features flaps arranged in a cone shape around the disc. This design provides excellent contact with the workpiece, better heat distribution, and a longer life compared to flat designs—plus it delivers a more consistent finish.
Is this a quick change system, and why does that matter?

Yes! The quick change feature means you can swap discs in seconds without tools. This saves you valuable time on the job and reduces downtime, so you stay productive and efficient throughout your workday.
What do the measurements 5 in x 5/8 in-11 refer to?

The 5 in is the diameter of the flap disc, and the 5/8 in-11 is the arbor hole size and thread specification. This sizing ensures proper fit and secure attachment to your angle grinder.
How many discs come in each case?

Each case contains 10 flap discs, giving you plenty of inventory to keep your work moving without frequent reorders.

Premium Performance 3M Cubitron 3 Flap Disc 1169F

The 3M Cubitron 3 Flap Disc 1169F represents an advanced abrasive solution engineered for demanding grinding and finishing applications. This durable disc combines the practical benefits characteristic of quality flap discs—including excellent surface conformability and user-friendly operation—while significantly reducing the potential for surface gouging. The innovative design makes it an ideal choice for professionals seeking reliable, consistent results across a variety of metal working tasks.

At the core of this product's superior performance lies 3M's proprietary Precision-Shaped Grain technology, which has been specially re-engineered to feature curved sides that enhance cutting efficiency. Unlike conventional abrasive materials that primarily compress and plow through workpieces, the geometrically optimized grains in the 1169F continuously fracture and expose fresh, razor-sharp cutting edges. This self-sharpening characteristic extends the disc's operational lifespan while maintaining impressive cutting rates from initial use through the end of the disc's service life. The polyester backing provides structural durability necessary for sustained high-pressure applications.

The performance advantages of the 1169F are quantifiable and significant. Testing demonstrates that this disc removes up to 49% more total material compared to the 3M Cubitron II Flap Disc 969F in the 40+ grade specification, and exceeds the 3M standard Flap Disc 769F 40+ grade by up to 66% in material removal rate.

Primary Applications

Weld grinding and weld spatter removal
Light to medium grinding operations
Beveling tasks
Deburring and edge refinement
Surface blending and finishing
General surface preparation
Scale removal
Work on edges and contours

Operational Efficiency Advantage

A notable benefit of the 1169F lies in its finishing capability. Under typical operating conditions, this flap disc produces a surface finish approximately one grade finer than a conventional fiber disc of equivalent grit rating. This characteristic allows operators to consolidate grinding and finishing into a single operation, effectively eliminating the need for multiple disc changes and reducing overall processing time on many projects.
