Shineboc 40-Piece Zirconia Sanding Belts 40-400 Grit | 1/2 x 18 in | Heavy-Duty Long-Lasting

Shineboc presents a 40-piece zirconia sanding belt set designed for belt sanders and a variety of materials. Each belt uses blue zirconia grains renowned for hardness and resilience, paired with a waterproof resin bond that helps maintain steady performance even during longer sanding sessions. The result is efficient material removal combined with a smooth finish on multiple substrates.

Six grit sizes for versatile results

The included grits are 40, 60, 80, 120, 180, and 240, giving you a full spectrum from aggressive stock removal to fine refinement. This variety lets you switch seamlessly between tasks like rust removal on metal, shaping wood, and preparing stainless steel surfaces without frequently swapping belts.

• 40 and 60 grit excel at rapid material removal on metal and wood
• 80 and 120 grit optimize shaping and smoothing
• 180 and 240 grit enable final finishing and detailing

Durable construction for demanding workloads

Blue zirconia grains provide high hardness and endurance, while the waterproof bonding helps maintain adhesion. A resin-bonded layer supports strong grain attachment, reduces clogging, and aids heat dissipation for longer sanding sessions without frequent belt changes.

• Bi-directional tape seams stay smooth and consistent
• Resin-bonded construction minimizes grain shedding and maintains performance

Wide compatibility and practical use

These belts are suitable for metal, wood, automotive parts, furniture, and stainless steel projects. Use them to prep surfaces, remove rust, smooth edges, and refine contours, all with belts designed to last across multiple projects.

Tip: start with the lowest grit to shape, then progress to finer grits for a cleaner finish. Apply steady, light pressure and maintain even motion for best results.
