5" Indasa Rhynogrip White Line Hook & Loop Sanding Discs — Solid, 50/Box

Indasa 5" Hook & Loop Discs for Fast, Economical Dry Sanding

Short answer: Indasa Rhynogrip White Line 5-inch discs give boatyards, fiberglass shops, paint departments, composite fabricators and woodworkers a dependable everyday abrasive at a strong per-disc value. The hook-and-loop grip backing makes grit changes fast, while the aluminum oxide abrasive provides an aggressive initial cut and reliable stock removal.

These are solid, no-hole discs supplied 50 per box. Use them on a compatible 5-inch hook-and-loop backing pad for dry sanding.

Why Choose Rhynogrip White Line?

• Fast initial cut: Aluminum oxide abrasive removes material efficiently.
• Quick grit changes: The grip backing attaches and removes without adhesive release paper.
• Clog-resistant fine grits: A lubricant coating on applicable grits helps extend useful sanding life.
• All-around value: A practical choice for production shops and routine repair work.
• Consistent package: Every available grit is sold 50 discs per box.

General Grit Selection Guide

This chart is a general starting point. Always follow the primer, paint, gelcoat or coating manufacturer’s required sanding schedule.

Fit and Attachment

Use these discs with a 5-inch hook-and-loop/grip backing pad. The solid face maximizes abrasive coverage but does not provide through-disc dust extraction. For active dust extraction, choose an Indasa disc with the hole pattern that exactly matches the backing pad.

Hook & Loop or PSA?

Choose hook-and-loop when you change grits frequently or want to remove and reuse a serviceable disc. Choose 5-inch Indasa Rhynostick PSA discs when your sander has a stick-on pad and you want firm adhesive attachment for longer production runs.

Frequently Asked Questions

How many discs are in a box?

Rhynogrip White Line 5-inch solid hook-and-loop discs are sold 50 discs per box.

Can I use these discs for wet sanding?

No. This White Line product is designed for dry sanding. Use a wet-sanding abrasive specifically rated for water when the process requires wet sanding.

Will these fit my 5-inch random-orbital sander?

They fit a 5-inch sander equipped with a compatible hook-and-loop backing pad. They will not attach correctly to a PSA-only pad.

Do these discs work with dust extraction?

This listing is for solid discs without extraction holes. Use a perforated disc whose hole pattern matches the backing pad when through-disc extraction is required.

Which grit should I use before paint or primer?

The correct grit depends on the coating system and the condition of the surface. Follow the coating manufacturer’s technical data sheet, or contact Fiberglass Florida with the exact primer or topcoat being applied.
