1550 Siapower 6″ Sanding Disc 100 Grit – 48 Hole Format

The 1550 Siapower 6″ sanding disc (100 Grit) is engineered to tackle the toughest surface preparation tasks with ease. Featuring a mixed grit composition with high-performance ceramic content, this abrasive delivers aggressive cutting action and exceptional stock removal rates. Whether you are leveling body filler in an automotive shop, shaping hard woods, or grinding down impurities on industrial metals, this 48-hole disc ensures you complete the heavy lifting quickly without sacrificing the consistency of the scratch pattern.

Exceptional Durability and Cost Efficiency

Designed for heavy-duty environments, the 1550 Siapower is built on a robust d-wt FSC-certified paper backing that withstands the rigors of machine sanding. This durable construction, combined with advanced resin-over-resin bonding, significantly extends the lifespan of the disc. By resisting edge wear and maintaining abrasive sharpness longer than standard discs, the 1550 Siapower reduces the frequency of disc changes, ultimately lowering material costs and increasing workshop productivity.

Versatile Application for Professional Results

This 100-grit abrasive is the ideal solution for the intermediate stages of surface repair. It excels at sanding out unevenness at the edges of repaired surfaces, flatting composite materials, and preparing surfaces for finer finishing steps. Compatible with a wide range of materials—including epoxy primer coats, glass-fiber reinforced plastic (GRP), gelcoats, and acrylics—the 1550 Siapower ensures a uniform surface profile that minimizes rework and prepares the substrate perfectly for subsequent coating layers.
