Product Number 305EA

3M™ Trizact™ Cloth Belt 305EA features an aluminum oxide mineral constructed on a very flexible JE-weight backing. It is resin bonded for heat resistance and contains a grinding aid to assist in cutting and keeping the work piece cool. This belt offers outstanding consistency and long belt life in both robotic and offhand applications. It is available in micron grades A5 and A3.

  • Excellent finish consistency from day one for final finish and pre-polish applications
  • Aluminum oxide grain cuts fast, stays sharp
  • Engineered for dry sanding applications, runs cooler
  • Proprietary abrasive mineral runs with less pressure, cleaner, cooler and with fewer belt changes
  • Fewer steps and fewer rejects means lower grinding cost per part

Fast, Fine, Consistent Finishes

For fast, fine, consistent finishes, our 3M™ Trizact™ Cloth Belt 305EA is a go-to belt. Microreplicated Trizact abrasive grain is engineered to start sharp and stay sharp longer, delivering less variability than conventional abrasives throughout its life. 3M developed this enhanced product to address final finish and pre-polish applications where fine, precise finishes are needed.

This belt uses aluminum oxide, a high-purity, tough mineral primarily used for precision grinding of steels and hard alloys, on a very flexible JE-weight rayon cloth backing. A resin bond adds heat resistance and a grinding aid to keep the work piece cool for dry sanding applications. The belt is available in a variety of forms including narrow, file, portable pump sleeve, and wide and flat finishing belts.

Science of Abrasion: Microreplicated Abrasive Mineral

Derived from patented 3M microreplication technology, Trizact abrasives consist of very small, precisely-shaped, three-dimensional structures distributed uniformly over the abrasive backing. Unlike conventional abrasives, which are constructed from randomly spaced and irregularly shaped minerals, the uniform configuration of Trizact abrasives helps deliver more consistent finishes with higher cut rates, and cooler grinding and finishing temperatures.

Recommended Applications

Choose 3M's Trizact Cloth Belt 305EA where fine, precise finishes are needed and for pre-polish and pre-plate finishing applications on stainless steel, cobalt chrome, titanium, and zirconium substrates, such as motorcycle parts, golf clubs, and sporting goods products. The belt works well for final steps in casting and forging, dimensioning, and scratch refinement in the manufacture of surgical and orthopedic devices.

The Trizact Advantage

The finer finishes that 3M Trizact Cloth Belt 305EA achieves and reduced downstream polishing time, due to fewer steps and fewer rejects, equals greater productivity and lower grinding cost per part. 3M product innovation and technical expertise, combined with over a century of practical abrasives application experience, can help you meet today's demanding quality, cost, material, and turnaround challenges. See how more efficiency can save you money and protect your product quality — and how 3M products support a more consistent and predictable process from start to finish.
