Lee Valley 3M Trizact Sharpening Belts

These are not your typical aluminum oxide belts. The grit particles are stacked in multiple layers forming uniform rows of tiny pyramidal structures that are designed to shed grit evenly, constantly exposing fresh layers of sharp particles as wear occurs.

Not only does this let the belts cut quickly and produce a consistent finish, but they significantly outlast standard belts, remaining effective longer, since the particles do not become rounded in use. Resin-bonded to a heavy X-weight cloth backing, the abrasive has a low-friction coating to minimize heat build-up.

The 1″ wide belts are available in 30″ and 42″ sizes in five grits, from 240x (80µ) for aggressive material removal, through successively finer grits for polishing, up to an ultra-fine 2000x (6µ).
