Indasa Rhynolock 3" Surface Conditioning Locking Discs, 8003 Series
Product Overview
Indasa 3" Surface Conditioning Locking Discs – 8003 Series are professional-grade non-woven abrasive discs designed for surface conditioning, blending, cleaning, and rust removal. These discs use an abrasive-impregnated web that produces a clean, paintable surface without damaging the substrate, as stated in the Indasa product sheet (“Produces a clean paintable surface without damaging substrate”).
The flexible open-weave construction conforms easily to contours and edges, while the high-strength resin bond minimizes grit shedding (“Minimal grit shedding”). The QuickFix R-Type (Type III) roll-on screw attachment provides fast disc changes and is fully compatible with Roloc®-type systems.
Available in Coarse (Brown), Medium (Maroon), and Very Fine (Blue) grits.

SMSDistributors Expert Notes
The 8003 Series offers the same high-performance non-woven construction as the 2" version, but with a larger 3" footprint for increased coverage and smoother blending on wider surfaces. The abrasive-impregnated web and resin bond deliver predictable finishing results and reduced grit shedding, improving both performance and lifespan.
The QuickFix R-Type attachment makes these discs ideal for automotive, marine, and industrial environments where fast disc changes are essential. The flexible open-weave structure prevents loading and keeps the disc cool, making it safe for heat-sensitive materials.
Color-coded grits (Brown = Coarse, Maroon = Medium, Blue = Very Fine) simplify selection and ensure consistent finishing results across different applications.
