The 3M™ Trizact™ Cloth Belt 337DC delivers consistently in intermediate to final finish, medium pressure applications. Designed with aluminum oxide and a grinding aid on a durable X- weight cloth backing, this belt is available in widths from 1/2 to 24 inches and grades from A300 to A30.
- Macroreplicated abrasive "bricks" contain multiple layers of abrasive mineral, "channels" keep remove swarf and keep work surfaces cleaner
- Controlled mineral breakdown delivers more consistent, predictable finishes over the life of the belt
- Durable cloth belt is frequently able to grind and finish in one operation
- Grinding aid reduces friction and keeps workpiece cool for dry grinding applications
- Extra-long belt life reduces abrasive cost and inventory

What is the 3M™ Trizact™ Cloth Belt 337DC?
The 3M™ Trizact™ Cloth Belt 337DC is an abrasive belt made with microreplication technology for consistent cutting action and longer abrasive life. It has a film-lok backing that securely attaches to a back-up pad, which reduces vibration and enhances operator comfort.
What are the dimensions of this belt?
This particular belt comes in a length of 132 inches, a width of three inches, and with five liners per case.
How durable is it?
The A100 X-weight material used provides long-lasting durability over extended periods when heavy machinery or other aggressive equipment use contacts the abrasive.
Q. Is it easy to attach or remove from my tools?
. Yes! Thanks to Film-lok attachment system, changing or attaching these belts on your power tools will be quick and effortless while staying securely attached while you're working on surface finishing jobs without any flexing whatsoever at high speeds.
The 3M™ Trizact™ Cloth Belt 337DC is a durable and high-performing abrasive belt that owes its consistent sustained cut rate to its uniquely engineered "bricks and channels" macroreplicated abrasive structure. The uniform abrasive "bricks" keep fresh cutting mineral constantly at the working surface, while the "channels" sweep debris away to discourage loading and keep the substrate clean.
The "bricks" consist of layers of mineral and grinding aid, up to 4 times as much as conventional aluminum oxide belts of the same grade. These dense layers of abrasive mineral lead to extra-long life and extremely consistent performance. The grinding aid protects heat-sensitive alloys from damage and reduces rework. Trizact belts start sharp and stay sharp, delivering a consistent cut that can often consolidate or eliminate process steps. In many cases, Trizact™ 337DC has the capacity to grind and finish in one step.Microreplication: Engineering Surface Geometry
Building upon the principles of microreplication, 3M scientists developed larger, more diverse abrasive structures —cubes, spheres, ridges — identical in shape and optimized for a variety of applications. Microreplication allows 3M to design abrasives with varying shapes and formulations, to control the level of breakdown, cut, finish, and life.
These abrasive structures are arrayed precisely and uniformly across a film or cloth backing in a pattern calculated to deliver sustained cut rate and eliminate belt-to-belt variation.Made to Tackle Difficult Metals
Trizact was developed especially for finishing more difficult processing materials like titanium, cobalt, stainless steel, as well as all exotic alloys in the aerospace, aviation, and medical industries. It is also effective for finishing applications on carbon steel, copper, bronze, aluminum, composite materials, and synthetics.Recommended Applications
Use for dry intermediate finishing, blending, scratch refinement, or final dimensioning on robotic, semi-automated, automated, off-hand equipment, and portable file belt tools. Use Trizact™ Cloth 337DC belts with:
- Medium hardness contact wheels (50-70 Shore A)
- Rubber contact wheels
- Smooth face to gentle serrated contact wheel
To prepare drawn carbon steel truck exhausts from rough to pre-plate finishes in as few steps as possible, we used a grade sequence of A100, A65, A30. Trizact™ 337DC outlasted a competitor by 2:1. For blending, final dimensioning, and finishing of turbine engine components, the grade A45 Trizact 337DC belt outlasted a competitor's belt by 4:1 times and produced a finer finish.Creating More Perfect Surfaces
Microreplication is only one of 3M's platform of core technologies. Its perfectly calibrated arrays are designed to give materials new physical, chemical, or optical properties. The science that makes 3M's structured abrasives wear more evenly, last longer, and provide more pristine finishes on delicate components like medical implants is also the science that makes traffic signs brighter, and exterior building illumination capture and reflect light more brilliantly.
