3M 33443 Cubitron II File Belt 36 Grit 1/2 in x 18 in

The 3M Cubitron II File Belt 786F is a best-in-class abrasive belt designed for use with 3M File Belt Sanders for demanding tasks like grinding out rivets and removing spot welds. This premium abrasive delivers 30% faster cutting and lasts 2x longer than conventional ceramic abrasives. This specific model (33443) features 36+ grit rating and measures 1/2 inch x 18 inches (12.7mm x 457.2mm), with 10 belts per box.

Precision-Shaped Grain Technology:

• Features Precision-Shaped Grain (PSG) technology with uniformly sized ceramic grains precisely shaped into triangular structures that slice through metal rather than plowing through it
• Grains are electrostatically oriented for efficient cutting and even wear, fracturing during use to maintain sharp abrasive edges
• Grains of ceramic/aluminum oxide blend are precisely-shaped, uniformly-sized and vertically oriented for fast cutting performance

Superior Performance Features:

• 3M Precision Shaped Grain is resin-bonded on heavy duty backing for consistent finish, cooler operation and two times more belt life
• Cubitron II abrasives run cooler, reducing risk of metal discoloration/oxidation and heat related stress cracks
• Grinding aid further enhances cooler running on high-strength steel
• Features polyester backing material for durability and dry use applications

Ideal Applications:

• Superior alternative to spot weld drilling in body shop environments
• Perfect for tough detail work including cleaning, deburring, blending and finishing in small confined spaces
• Excellent for cleaning and prepping brake caliper pockets, removing rust and brake dust
• Ideal for cleaning wheel rims to remove corrosion prior to tire mounting and prepping surfaces for wheel weights
• Effective for prepping steering knuckle housings, getting into deep indentations and complex surfaces

The fast cutting action helps eliminate burning and other forms of thermal damage during grinding operations. This belt is designed for industrial and occupational use with file belt sanders.
