3M 577F Zirconia Alumina (ZA)

• Available Grits: P40, P60, P80, P120
• Abrasive Mineral: Premium Zirconia Alumina with active grinding aid on heavy YF-weight cloth backing.
• Performance: Continuous self-sharpening grain, high wear resistance, and superior heat dissipation during heavy stock removal.
• Recommended Workpieces: Stainless steel, carbon steel, alloy steels, non-ferrous metals (aluminum, brass, bronze), and hardwoods.

VSM Ceramic XK850X (CE)

• Available Grits: P36, P60, P80, P120
• Abrasive Mineral: Microcrystalline ceramic grain with top-size lubricant coat on heavy polyester cloth backing.
• Performance: Aggressive cut rate, self-regenerating cutting edges, and cool grinding to prevent workpiece discoloration or burning.
• Recommended Workpieces: High-hardness alloy steels, carbon steel, forged steel, cast iron, and stainless steel pipe fabrication.

3M Trizact 237AA Microreplication Cloth Belts

• Available Micron Grades: A3 (approx. P2500–P3000), A5 (~P2000), A6 (~P1500), A16 (~P1200), A30 (~P600), A65 (~P280)
• Mineral & Structure: 3M microreplication technology forming microscopic 3D pyramids of aluminum oxide mineral on X-weight flexible cloth.
• Performance: Uniform scratch depth, constant cutting rate throughout belt life, reduced processing steps, and predictable surface finishes.
• Recommended Workpieces: Intermediate finishing, contour blending, pre-plate preparation, and mirror-finish pre-polishing on stainless steel and alloys.

Aluminum Oxide (AO) Multi-Purpose Sanding Belts

• Available Grits: P40, P60, P80, P100, P120, P150, P180, P240, P320, P400, P600, P800, Dry White P1000, P1200, P1500
• Backing & Bond: Heavy-duty polyester/cotton cloth backing with full resin bond for high mechanical tensile strength.
• Applications: Multi-purpose grinding, stock removal, and smoothing on wood, furniture, flooring, plastics, soft metals, and composite materials.

3M Scotch-Brite Non-Woven Nylon Surface Conditioning Belts

• Available Grades: Brown (Coarse / P100–P150), Red (Medium / P180–P240), Blue (Fine / P320–P400), Grey (Very Fine / P600)
• Web Structure: 3D non-woven nylon mesh infused with abrasive grains, resisting loading and running cool.
• Applications: Rust, tarnish, and scratch removal; deburring edges; achieving uniform satin or decorative brushed finishes on stainless steel and aluminum.

Wool Felt Mirror Polishing Belts

• Thickness: High-density wool felt, 3–4 mm thickness
• Structure: Seamless jointless ring design for smooth, bump-free rotary polishing.
• Applications: Use with polishing compounds, diamond pastes, or buffing rouges for high-gloss mirror buffing on stainless steel, brass, copper, and precious metals.
