3M™ Cubitron™ Grinding Disc 3 98291 – Ø 230 mm x 7 mm x 22.23 mm

The 3M™ Cubitron™ 3 Disc (ID 7100303979) is a Type 27 bonded abrasive, developed for professionals who require extreme performance in heavy-duty material removal. Backed by over a century of 3M innovation, this next-generation disc is optimized for fast rotation and sustained effectiveness on hard metals.

Next Generation Benefits and Features

  • Reengineered PSG Technology: Inside is a contoured ceramic grain enhanced by a new patented molecular bonding technology. The even sharper tips fracture in a controlled manner to continuously regenerate, ensuring a cooler cut and optimal mineral consumption.
  • Doubled Efficiency: Tests show that the 98291 removes up to 2 times more material than 3M™ Cubitron™ II discs, reducing total operating costs.
  • Peak Performance: Cutting speed is increased by 14% compared to the previous generation, allowing you to complete demanding operations with less fatigue and in less time.
  • Depressed Center Design (T27): The ergonomic shape allows the disc to be used at different angles to the workpiece, offering versatility at every stage of grinding.
  • Cold Work: PSG granule technology minimizes thermal friction, preventing discoloration and structural damage even on sensitive substrates such as stainless steel.

Technical Specifications

  • Overall Diameter: 230 mm.
  • Thickness: 7 mm.
  • Center Hole Diameter: 22.23 mm.
  • Grit: 36+ (Extra Aggressive).
  • Maximum Speed: 6,650 rpm.
  • Wheel Type: Type 27 (depressed center).
  • Abrasive Material: Precision Shaped Ceramic.

Applications and Sectors

The 98291 model is the gold standard for heavy metalworking, aerospace, and oil and gas applications:

  • Heavy-duty operations: Heavy weld removal, metal removal, and plate grinding.
  • Edge processing: Chamfering, chamfering and right-angle grinding.
  • Compatible substrates: Stainless steel (Inox), mild steel and aerospace alloys.

Technical Tip: To maximize the potential of the Cubitron™ 3, pair the disc with a powerful and robust 3M angle grinder. Always use approved guards and never exceed the specified 6,650 RPM.
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.
