3M 337DC Trizact Gator Cloth Belts 25mm x 760mm for Knife Polishing – Pack of 12-A30

Description

Our 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.

Long Life, Sustained Cut, Consistent Performance 
Our 3M™ Trizact™ Cloth Belt 337DC owes its durability and consistent sustained cut rate to its uniquely engineered “bricks and channels” macroreplicated abrasive structure. Uniform abrasive “bricks” keep fresh cutting mineral constantly at the working surface and “channels” sweep debris away to discourage loading and keep the substrate clean.

Delivers consistently in intermediate to final finish, medium pressure applications

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 reducing rework. Trizact belts start sharp and stay sharp. The consistent cut Trizact belts (PDF, 13 Mb) deliver can often consolidate or eliminate process steps. In many cases, Trizact™ 337DC has the capacity to grind and finish in one step. 

 
Microreplication abrasives have varying shapes and formulations, to control the level of breakdown, cut, finish and life

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. 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 possi
