180 MM 3M™ CUBITRON™ II VARIOUS GRITS (CF 10 PCS) 969F FLAT FLAP DISC

3M™ Cubitron™ II Flap Disc 969F – Ø 180 mm x 22 mm, Type 27

The 3M™ Cubitron™ II Disc 969F (969F Series) is designed to deliver best-in-class performance for demanding applications such as heavy-duty grinding and heavy weld removal. Its design is optimized for versatility and ease of use, reducing the risk of gouging compared to fiber or hard discs.

3M™ Precision Shaped Grain Innovation

This disc uses micro-replicated ceramic granules that cut cleanly into the metal instead of "plowing" it like traditional products. This technology guarantees:

• Constant cutting speed: Individual blades gradually fragment, exposing new sharp mineral throughout the life of the disc.
• Less physical effort: The PSG's rapid removal rate allows the job to be completed with less manual pressure, increasing operator comfort.
• Superior Productivity: Designed to deliver more completed parts per single disc, reducing downtime for abrasive changes.

Operational Benefits

• Cold Cut: Includes a grinding additive that reduces heat development, preventing discoloration and burning of the substrate.
• YF Weight Support: The durable polyester backing ensures mechanical stability and tear resistance even under extreme workloads.
• Smooth Finish: Despite its aggressiveness, the lamellar structure allows for a high-quality finish, ideal for projects where aesthetics are key.
