Maximum Removal Power on Large Structures: Cubitron™ 3 1169F Type 29

The 3M™ Cubitron™ 3 Flap Disc 1169F, 180 mm , conical configuration (Type 29) is the pinnacle of abrasive technology for heavy-duty removal over large surfaces. Featuring newly re-engineered Precision Shaped Grain (PSG) technology with curved sides, this disc cuts through metal 66% faster than previous models, providing exceptional durability and a consistent cut. The conical shape is designed to provide maximum surface contact during angled use, making it ideal for grinding large welds, chamfering, and heavy-duty deburring on carbon steel and stainless steel. Designed to withstand high pressure on high-powered grinders, the 1169F reduces processing time and operating costs, often delivering a finish ready for the next step in a single operation.

3M™ Cubitron™ Flap Disc 3 1169F – Ø 180 mm, Conical (T29)

The 3M™ Cubitron™ 3 1169F disc in the 180 mm format represents the most advanced solution for heavy-duty industries. Featuring an ultra-rigid Y-type polyester backing, this disc is built to maintain extreme cutting performance even under heavy loads and high pressures.

Technological Innovation and Operational Advantages

  • Re-engineered Precision-Shaped Grain: The patented ceramic grain with curved edges continuously fractures to create consistently sharp tips. This prevents overheating of the workpiece and ensures a clean cut of metal.
  • Class-leading material removal: Removes up to 49% more material than the Cubitron™ II 969F and up to 66% more than the 769F series.
  • Conical Design (Type 29): The inclined shape maximizes contact surface area in angled machining, making it easier to grind complex weld seams and machine edges on large sheets.
  • Long Service Life: Controlled fragmentation of the blades constantly exposes new mineral, maintaining a constant cutting speed throughout the entire life cycle (up to 10 years from production).

Technical Specifications

  • Overall Diameter: 180 mm.
  • Center Hole Diameter: 22.23 mm.
  • Disc Profile: Type 29 (Conical).
  • Abrasive Material: Precision Shaped Ceramic (PSG).
  • Backing: Y-Weight Polyester (High Strength).
  • Technical Expiration: 3650 days (10 years).

Grana Variants and Identification Codes

The 1169F 180mm conical model is available in the following variants (5-pack):

  • Grit 40+: For heavy grinding and fast removal (3M ID: 7100379344 | EAN: 00068060117458).
  • Grit 60+: For deburring and surface preparation (3M ID: 7100402380 | EAN: 04064035201678).
  • Grit 80+: For finishing and masking imperfections (3M ID: 7100400852 | EAN: 04064035201654).

Recommended Applications

Ideal for shipbuilding, railway, aerospace and heavy metalwork:

  • Grinding of large welds and chamfering of edges.
  • Removal of scale and welding burrs.
  • Preparation for painting and finishing of large flat areas.
  • Machining of stainless steel, carbon steel and heat-sensitive alloys.

Technical Tip: The 1169F disc produces a finer finish than a fiber disc of the same grit. This eliminates intermediate sanding steps, saving time and reducing the number of discs used.
Superior performance with 3M™ Cubitron™ 3: +56% material removed and faster cutting on stainless and steel. The new era of PSG abrasives.

3M™ Cubitron™ 3 is the direct evolution of Precision Shaped Grain (PSG) technology, redesigned to ensure an even more controlled fracture of the abrasive grain.

It is designed for high-intensity sectors such as heavy steelwork, stainless steel, shipbuilding, metalworking and robotic grinding.

The range includes fibre discs, grinding discs, cut-off discs and solutions for aggressive stock removal on alloy and high-strength steels.

Compared to Cubitron™ II, the Cubitron™ 3 line offers faster cutting, less heat build-up and up to 56% more material removed.

Choose it for consistent productivity, reduced vibration and significantly longer abrasive life.

Avoid excessive pressure: the grain works best with steady feed, exploiting the self-sharpening PSG geometry.

Technical tip: always use original 3M backing pads to keep the optimal working angle and maximise disc life.
