3M™ Trizact™ Cloth Belt 237AA uses proprietary microreplication technology where micron-graded aluminIum oxide particles are formed into tiny pyramids of abrasive mineral and then coated on an X weight cloth backing. As these pyramids wear, fresh, sharp mineral is continually exposed to produce a consistent cut and a predictable, fine finish.

For use on: Aluminium, Carbon Steel, High Nickel Alloy, Soft Metals, Stainless Steel, Titanium/Zirconium

  • Good starting point for finishing applications
  • Use dry
  • Ideal for intermediate finishing and fine polishing prior to plating or buffing
