3M Cubitron II Abrasive Belts 767F
Cubitron II is an advanced belt technology that outlasts simple ceramic belts.
Cubitron is the engineered next-generation abrasive mineral, manufactured grains of ceramic/aluminum oxide blend are precisely-shaped, uniformly-sized and vertically oriented.
As opposed to a standard ceramic belt where at any point there will be some sharp, some dulled - and after a while - some abrasive grains missing or worn down, Cubitron mineral abrasive belts wear down on collections of tiny particles for a longer lasting, more even grinding pattern.
This is the 767F - the model we recommend for knife making = hand grinding - due to less abrasive concentration than the more expensive 984F that requires much more pressure to get full belt life.
The lower abrasive consentration means hand grinding (as opposed to a machine applying higher pressure grinding) is enough force to get max value from the belts.
The reason these 3M belts are taking over for ceramic belts are:
- longer lasting by using "pyramics" of small mineral particles rather than larger, single ceramic particles
- more even finish by slowly wearing down pyramics of even grain size as opposed to uneven ceramic particles being resharpened or dulled, eventually ripped off the belt as the belt wears down

This is what 3M has to say about the Cubitron II technoloy:
3M™ Cubitron™ II Abrasives. These premium abrasives belts, discs and wheels are powered by 3M Precision-Shaped Grain — the result of decades of technological advances in ceramic abrasive and microreplication technologies. As the triangular shaped grain wears, it continuously fractures to form sharp points and edges that slice through metal, wear evenly and provide super-long life and consistency at any grinding pressure.
The bottom line: 3M™ Cubitron™ II Abrasives cut faster, last longer, and help lower your production costs.
