The 3M Hookit Clean Sanding Disc 236U (55500) is a premium 5-inch aluminum oxide sanding disc engineered for superior dust extraction and long-lasting cutting performance. Featuring 3M's proprietary multi-hole CW Array hole pattern, this disc evacuates dust at a significantly higher rate than standard 5- or 6-hole products, keeping the sanding surface clear and extending disc life.
Built on a C-weight paper backing, the 55500 provides the durability needed for aggressive sanding while minimizing edge wear. The open-coat construction combined with a load-resistant coating prevents premature clogging, ensuring consistent cut even on materials prone to loading such as softwoods, paints, and sealers.
Key Features:
- Proprietary Multi-Hole Pattern: CW Array hole design provides superior dust extraction — no hole alignment required with the sanding pad
- Aluminum Oxide Abrasive: Premium mineral with resin bond cuts faster and lasts longer than traditional garnet
- C-Weight Paper Backing: Supports aggressive sanding and resists tearing for extended disc life
- Open Coat Construction: Prevents disc loading and maintains cutting ability throughout the disc's life
- Load-Resistant Coating: Keeps the disc cutting efficiently on paints, sealers, and softwoods
- Hookit Hook & Loop Attachment: Fast, easy disc changes without tools — discs are reusable for the full abrasive life
- Max Speed: 10,000 RPM / 12,000 OPM
- Grit: P180 | Color: Gold | Diameter: 5 inches
