1550 Siapower 6″ Sanding Disc 600 Grit – 48 Hole Pack

The 1550 Siapower 6″ sanding disc (600 Grit) is the premier choice for ultra-fine surface refinement. Featuring semi-friable aluminum oxide (blue-fired) abrasive grain, this disc is engineered to deliver a remarkably consistent and shallow scratch pattern. It is designed for the most critical stages of finishing, where precision is paramount. Whether you are preparing a surface for the final clear coat or rectifying minor imperfections in automotive refinishing, this disc ensures a high-quality finish with minimal effort.

Advanced Stearate Coating and Flexible Design

To maintain peak performance at such a fine grit, the disc is equipped with a specialized stearate coating. This active agent significantly reduces heat generation and prevents the fine dust from clogging the abrasive surface, ensuring a smooth, uninterrupted sanding process. Built on a lightweight b-wt FSC-certified paper backing, the disc offers exceptional flexibility, allowing it to adapt perfectly to contours and curves without risking cut-throughs on delicate edges or complex profiles.

Professional Grade Matting and Blending

This 600-grit abrasive is the specialist tool for matting and blending. It is highly effective for keying old and new lacquers to create a seamless transition during spot repairs and blending zones. The 48-hole dust extraction pattern works in harmony with the anti-clog coating to keep the work surface spotless. It is suitable for a wide variety of materials, including acrylic glass, cathodic dip primer coats, and gelcoats, delivering a uniform matte surface ready for the next step in the finishing process.
