Sanding Discs - Aluminium Oxide

EXTRACUT Aluminum Oxide Sanding Discs professional-grade abrasive discs designed for stock removal, surface preparation, and finishing on wood, metal, and composite materials. Available in both PSA (Pressure-Sensitive Adhesive) and hook-and-loop formats, these discs deliver consistent cutting performance across a full range of grits from coarse 36-grit stock removal through ultra-fine 400-grit finishing.

Key Features

• Premium Al₂O₃ Grain — Sharp, durable aluminum oxide abrasive grains provide fast cutting and long life on wood, mild steel, and aluminum.
• PSA / Hook-and-Loop Options — Available in pressure-sensitive adhesive backing for permanent-mount applications or hook-and-loop for quick-change convenience.
• Full Grit Coverage — Complete grit range: 36, 40, 60, 80, 100, 120, 150, 180, 240, 320, 400 — covering every stage from rough shaping to final sanding.
• Anti-Loading Coating — Open-coat construction with stearate or zinc stearate coating prevents loading when sanding soft materials like pine, MDF, and aluminum.
• Paper / Cloth Backing Options — C-weight paper for fine finishing; X/Y-weight cloth for heavy-duty grinding applications.
• Uniform Grain Distribution — Electrostatic grain placement ensures even abrasive distribution for consistent scratch pattern and finish quality.

Applications

Woodworking (surface prep, between-coats sanding, final finish), metal fabrication (rust removal, paint stripping, weld smoothing), automotive bodywork (body filler sanding, primer surfacing), furniture manufacturing, and DIY projects requiring reliable, consistent abrasive performance.
