PRODUCT FAQ

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

This is a 40+ grit disc, which makes it ideal for aggressive grinding and material removal on metal surfaces. It's designed specifically for metal applications and delivers excellent performance on steel, stainless steel, and other ferrous metals.
Will this flap disc work with my existing quick change system?

Yes! This disc features the T29-Conical Quick Change design, which is compatible with standard quick change systems. The 3/8 in-24 connection ensures a secure fit with compatible angle grinders and other power tools.
How many discs come in each package?

Each case contains 10 flap discs, giving you plenty of supply for your grinding operations. This bulk packaging helps reduce downtime and keeps you well-stocked.
What makes Cubitron 3 different from other flap discs?

Cubitron 3 features advanced ceramic grain technology that stays sharper longer and cuts faster than conventional abrasives. You'll experience less heat generation, longer disc life, and improved productivity on the job.
What is the diameter and is it suitable for my 4-inch grinder?

This flap disc is 4 inches in diameter, making it a perfect fit for standard 4-inch angle grinders. The conical shape also provides excellent contact and consistent grinding results across the work surface.

Premium Performance 3M Cubitron 3 Flap Disc 1169F

The 3M Cubitron 3 Flap Disc 1169F represents an advanced abrasive solution engineered to deliver exceptional performance across a wide range of grinding and finishing applications. This versatile flap disc combines the inherent benefits of traditional flap disc technology—such as superior conformability and user-friendly operation—with innovative enhancements that significantly reduce the risk of surface gouging. The integration of durable polyester backing material ensures extended service life and reliable performance even under demanding working conditions.

Enhanced Cutting Technology and Performance Advantages

At the core of the 1169F's superior performance lies 3M's proprietary Precision-Shaped Grain technology, which has been re-engineered with a curved-edge design. This sophisticated abrasive grain structure is engineered to continuously fracture and reshape during use, consistently exposing sharp cutting points that efficiently slice through metal substrates with minimal plowing action. This distinctive fracturing mechanism fundamentally differentiates the product from conventional abrasive solutions, which typically operate through a plowing rather than slicing action. This technological advantage translates to exceptional longevity and sustained cutting efficiency throughout the entire service life of the disc.

When compared to predecessor products, the performance gains are substantial. The 1169F delivers up to 49% greater total material removal relative to the 3M Cubitron II Flap Disc 969F in the 40+ grit range, and demonstrates up to 66% improved material removal performance compared to the 3M Flap Disc 769F 40+ grade. These metrics underscore the significant advancement in abrasive technology incorporated into this product.

Versatile Application Range

The 3M Cubitron 3 Flap Disc 1169F is engineered to perform exceptionally well across medium to high-pressure grinding operations. Its robust construction and advanced abrasive formulation make it suitable for an extensive variety of metalworking tasks.

Weld grinding and weld spatter removal
Light grinding operations
Beveling and edge work
Deburring processes
Blending and finishing applications
Surface preparation and finishing
Scale removal
Work on complex edges and contoured surfaces

Efficiency and Finishing Quality

A notable advantage of the 1169F is its ability to combine grinding and finishing operations into a single step in many practical scenarios. Under standard operating conditions, the disc produces a finished surface quality equivalent to a fiber disc one grit grade finer than the 1169F itself. While traditional fiber discs may offer slightly faster cutting speeds, the 1169F eliminates the need for multiple abrasive changes during a typical job cycle, resulting in meaningful time savings and improved operational efficiency for users seeking to optimize their workflow.
