【Applications】
🪵 Woodcarving and Woodworking
80-grit for rapid shaping, 240-grit to smooth tool marks, 600-grit for pre-polishing, and 1,000-grit or higher for sanding prior to sealing.

🔩 Metalworking
Sanding stainless steel welds (180–320 grit), removing CNC machining marks (400–800 grit), achieving a final brushed or mirror finish (1500–7000 grit).

💍 Jewellery and Gemstones
Removing oxidation from silver jewellery, deburring copper pieces, polishing the inner walls of jade ring bands, and sanding amber without generating heat.

🧼 3D Printing Post-Processing
Removal of layer lines from PLA/ABS resin, trimming of support residue, and polishing of transparent parts to a crystal-clear finish.

🚗 Models and Moulds
Sanding of sprues on car models, and surface treatment of moulds following EDM machining.

【Package Contents】
Electric sander polishing heads × 15 (various grits and shapes)
As batches may vary, the actual shapes received may differ, but we guarantee coverage of key grits ranging from 80 to 7000.

【Precautions】
Before use, ensure the electric sander’s chuck is securely tightened to prevent parts from being flung out at high speed.
We recommend wearing safety goggles and a dust mask to avoid flying fine particles.
Use different grit sizes in sequence; do not skip too many grades (e.g. jumping directly from 240 grit to 1500 grit).
For high grit sizes (≥3000 grit), results are improved when used with a small amount of polishing wax or water.
Store in a dry environment to prevent the sandpaper from becoming damp and losing its grit.
