Description of Sungold Abrasives 91 205 400 Trinet Abrasive
Premium aluminum oxide refractors for extended life grain with zinc stearate for reduced loading. Unique mesh construction keeps dust from affecting final finish. Dust free sanding with most vacuum assist tools. Can be used with hook & loop machines or hand sanding. 2-3/4" width will work on hook & loop longboard automotive sanders'.
This product may appear decent for light sanding but is not fit for serious industrial and scientific usage.As my tests showed it lacks the cutting power needed to remove residue from the surface. The price is low, which is the only redeeming factor, but the quality is disappointing..
Pros
High-quality Trinet abrasive for efficient sanding
Cons
Some users have reported the abrasive wearing out quickly
