3M Cubitron II 984F PSG Grinding Belts – Professional Grade [1x30, 2x42, 2x48, 2x72]

The Coolest, Fastest Cut in the Industry

Stop fighting heat and start shaping steel with the belt that changed the industry. The 3M Cubitron II 984F isn't just a ceramic belt—it features 3M’s patented Precision-Shaped Grain (PSG) technology. These triangular ceramic grains are engineered to fracture as they wear, continuously exposing fresh, sharp cutting edges.

While conventional ceramic belts "plow" through metal (generating friction and heat), Cubitron II slices through it. This means you spend less time at the grinder and more time delivering a perfect edge.

Why Precision Sharpeners Choose Cubitron II:

• Cooler Grinding: PSG technology diverts heat into the swarf (metal dust) rather than your blade, protecting the temper and heat-treat of your steel.

• 4x Longer Life: Designed to outlast standard ceramic belts by up to 400%, saving you money and reducing belt changes mid-project.

• Consistent Scratch Pattern: Because the grains fracture uniformly, you get a predictable finish that makes your grit progression significantly easier.

• Reduced User Fatigue: The belt does the work. You don’t need to lean into the grinder to get the belt to "bite," allowing for more control and precision.

Technical Specifications:

• Mineral: 100% 3M Precision-Shaped Grain (Ceramic).

• Backing: Heavyweight YF-weight polyester (Waterproof for wet/dry use).

• Bonding: Resin bonded for high-heat resistance.

• Joint Type: High-strength film join (Bi-directional).

• Application: Ideal for heavy profiling, bevel grinding, and high-pressure metal removal on stainless, carbon steel, and cobalt alloys.

Pro-Sharpener’s Tip:

To get the most out of your Cubitron II, don't be afraid to apply pressure. These grains are designed to fracture under load. If the belt feels like it's "glazing," grab a hardened straight edge apply pressure slightly to "refresh" the cutting surface and reveal the next layer of PSG points.
