115 MM 3M™ CUBITRON™ II VARIOUS GRITS (CF 10 PCS) 969F FLAT FLAP DISC
Superior Cutting Power and Smooth Finish: Cubitron™ II Excellence in 115mm Format
The 3M™ Cubitron™ II Flap Disc 969F 115 mm is designed to exceed productivity standards in the most demanding grinding applications. Featuring patented Precision Shaped Grain (PSG) technology, this disc cuts cleanly into metal rather than plowing it, delivering exceptional cutting speed and significantly longer life than conventional ceramic abrasives. Its flat (Type 27) configuration, combined with a robust YF-weight polyester backing, makes it ideal for weld removal, heavy deburring, and edge bevelling on stainless steel and carbon steel. It includes a built-in cooling additive that prevents overheating of the workpiece, ensuring consistent results and a smooth finish from first to last flap.

3M™ Cubitron™ II Flap Disc 969F – Ø 115 mm x 22 mm, Type 27
The 3M™ Cubitron™ II Disc 969F (969F Series) is the ideal solution for high-pressure industrial applications where maximum removal and mechanical resistance are required. The ultra-resistant polyester backing provides the stability needed for the most demanding jobs.
3M™ Precision Shaped Grain Technology
The heart of this disc is a micro-replicated ceramic grain that continuously fractures into extremely sharp points. This self-sharpening process allows for:
- Maintain a constant cutting speed throughout the life of the disc.
- Drastically reduce the effort required by the operator.
- Outperform and outlast all traditional ceramic abrasives.
Benefits and Exclusive Features
- Cool Cutting: The integrated grinding additive minimizes heat development, protecting sensitive metals from discoloration and burning.
- YF Weight Support: Durable polyester layer allows for high pressure applications without structural failure.
- Ease of Use: Compared to hard or fiber disks, the lamellar structure reduces the risk of accidental scratching of the substrate.
- Professional Finish: Ideal for projects where the final aesthetic quality is fundamental.

Recommended Applications
Optimized for the metal fabrication and heavy carpentry industries:
- Grinding and heavy weld removal.
- Edge deburring and chamfering.
- Chamfering and finishing of flat surfaces.
- Machining of stainless steel, carbon steel, and heat-sensitive metals.
Technical Advice: To maximize performance, use the disc on angle grinders with enough power to maintain constant rpm even under heavy load.
3M™ Cubitron™ II is the generation that introduced the microreplicated PSG ceramic grain, revolutionising the way metals are cut and ground.
It is ideal for metal steelwork, industrial maintenance, welding and work on carbon steel, stainless and structural steels.
The range includes cut-off discs, fibre discs, flap discs, grinding discs and dedicated 3M ribbed backing pads.
Compared to traditional ceramic abrasives, Cubitron™ II ensures cooler cutting, less friction and a significantly longer service life.
Professionals choose it for consistent machining speed and an extremely competitive cost per piece.
Mistake to avoid: applying too much pressure, because the grain should not “plough” the workpiece but cut it cleanly.
Technical tip: always pair the correct 3M backing pad to keep the cutting geometry, reduce overheating and improve the finish.
