150 MM X 22.23 MM 3M™ CUBITRON™ 3 VARIOUS GRITS (CF 20 PCS) 1169F T29 CONICAL FLAP DISC

3M™ Cubitron™ Flap Disc 3 1169F – Ø 150 mm, Conical (T29)

The 3M™ Cubitron™ 3 Disc 1169F in the 150 mm format is a professional, ultra-high-performance abrasive, specifically developed for medium- and high-pressure industrial applications. Its advanced design combines the versatility of a flap disc with the removal power of next-generation Cubitron™ technology.

Technological Innovation and Performance

• Re-engineered Precision-Shaped Grain: The patented ceramic grain features curved edges that continuously fracture into sharp points. This allows for clean cuts into metal rather than plowing through it, reducing friction and heat buildup.
• Class-leading stock removal: Tests show this disc removes up to 49% more material than the Cubitron™ II 969F and up to 66% more than the 769F series (based on grit 40+).
• Consistent Cutting and Extended Life: The blades gradually wear down, always exposing new sharp mineral, ensuring a high cutting speed for the entire life of the disc, which can be up to 10 years from the date of manufacture.
• Conical Design (Type 29): Optimized to maximize surface contact in angled machining, facilitating chamfering and grinding of complex weld seams on large plates.

Grana Variants and Identification Data

The 1169F 150 mm model is available in the following grits to cover every production need:

• Grit 40+: For heavy grinding and fast stock removal (3M ID: 7100379505 | EAN: 00068060117472).
• Grit 60+: For deburring and surface preparation (3M ID: 7100379770 | UPC: 00068060117687).
• Grit 80+: For finishing, masking and removing imperfections (3M ID: 7100401211 | EAN: 04064035201661).

Recommended Applications

Designed for industries such as shipbuilding, railways, aerospace and heavy metal fabrication:

• Grinding of large welds and grinding of plates;
• Edge chamfering and heavy deburring;
• Removal of scale and preparation for painting;
• Machining of stainless steel, carbon steel and heat-sensitive alloys.

Technical Tip: The 1169F disc produces a finer finish than a fibre disc of the same grit, often eliminating intermediate steps and completing the grinding and finishing in one operation.
