Frequently Asked Questions
How does this compare to sandpaper for metal finishing?
Unlike sandpaper, these non-woven conditioning discs conform to contoured surfaces without gouging and resist loading for longer life. The open-web construction runs 40% cooler than traditional abrasives, preventing heat damage and extending disc life by 2× while maintaining consistent cutting action throughout use.
What size Roloc disc pad do I need?
Use a 3-inch Roloc TR disc pad with threaded hub that fits standard 1/4-inch collets. The threaded attachment screws directly onto compatible angle grinders and pneumatic tools with proper adapters, ensuring secure mounting at speeds up to 18,000 RPM.
How long does each disc typically last?
Each disc provides 15-30 minutes of active conditioning, depending on pressure and material hardness. Under normal use for surface conditioning and light deburring, performance remains consistent throughout the disc life, delivering approximately 2× the lifespan of comparable sandpaper discs.
Can these discs be used on stainless steel?
Yes, the medium-grade aluminum oxide formulation is specifically designed for stainless steel, mild steel, aluminum, nickel alloys, and titanium. The controlled cutting action removes 0.001-0.003 inches per pass, creating optimal surface profiles for coating adhesion without compromising dimensional tolerances.
Will these work with my existing tools?
These discs are compatible with any tool that accepts 3-inch Roloc TR attachments, including most angle grinders, die grinders, and pneumatic sanders when equipped with the appropriate Roloc disc pad. The universal threading system ensures compatibility across major tool brands.
