1550 Siapower 6″ Sanding Disc 150 Grit – 48 Hole Pack

The 1550 Siapower 6″ sanding disc (150 Grit) strikes the perfect balance between aggressive cutting and surface refinement. Engineered with a mixed grit composition containing high-quality ceramic, this abrasive ensures rapid stock removal while maintaining a consistent scratch depth. It is the ideal choice for intermediate sanding stages, allowing professionals to quickly transition from heavy bodywork to finer surface preparation without sacrificing speed or efficiency in high-paced automotive and industrial shops.

Optimized Durability on C-Weight Backing

Designed for longevity and flexibility, the 150-grit version utilizes a sturdy c-wt FSC-certified paper backing. This backing is lighter than the coarse grit versions, offering better adaptability to contours while retaining enough rigidity for flatting surfaces. The robust resin-over-resin bonding system secures the abrasive grains firmly, ensuring uniform abrasion throughout the disc’s life. This durability translates to fewer disc changes and lower material costs, even during intensive sanding of coatings and impurities.

Flawless Preparation for Primers and Paints

This 150-grit disc is specifically tailored for critical preparation tasks, such as fine sanding of primer fillers and flatting composite materials. Its precise scratch pattern is perfect for keying old and new lacquers, ensuring optimal adhesion for subsequent layers. With a 48-hole dust extraction pattern, it keeps the work surface clean and prevents clogging, making it highly effective for working on diverse materials ranging from epoxy primer coats and GRP to acrylic glass and plastics.
