1169F T27 FLAT FLAP DISC 125 MM X 22.23 MM 3M™ CUBITRON™ 3 VARIOUS GRITS CF 100 PCS

3M™ Cubitron™ Flap Disc 3 1169F – Ø 125 mm x 22.23 mm

The 3M™ Cubitron™ 3 Disc 1169F (ID 125 mm) is a professional, ultra-high-performance abrasive designed for medium- and high-pressure applications on angle grinders. Thanks to its heavy-duty Y-type polyester backing, it offers the robustness needed for the most demanding industrial applications while maintaining excellent ease of use.

Innovation and Superior Performance

• Reengineered PSG Technology: The patented curved-sided ceramic grain cuts cleanly into the metal instead of plowing it. This process reduces heat buildup and prevents discoloration on sensitive alloys.
• Record Removal: Comparative tests show that this disc removes up to 49% more material than the Cubitron™ II 969F and up to 66% more than the 3M™ 769F series (based on grit 40+).
• Consistent Cutting: The blades gradually fragment, always exposing new sharp mineral, ensuring that the cutting speed remains high throughout the life of the blade.
• Versatility of use: Excellent on carbon steel, stainless steel and other metal alloys.

Available Variants

The 1169F 125mm model is available in the following grits to cover the entire working cycle:

• Grit 40+: Ideal for heavy grinding and quick weld removal (3M ID 7100379332).
• Grit 60+: Optimal for deburring and surface preparation (3M ID 7100379508).
• Grit 80+: Perfect for finishing, masking and removing imperfections (3M ID 7100379211).

Recommended Applications

It is the standard of excellence for sectors such as aerospace, shipbuilding, railway industry and tank manufacturing:

• Grinding and grinding of welds;
• Edge chamfering and deburring;
• Calamine removal;
• Preparation for painting and surface finishing.

Technical Tip: Thanks to its conformability, the 1169F flap disc produces a finer finish than a fiber disc of the same grit. This often eliminates intermediate sanding steps, saving valuable time.
