Quick-Change Sand Disc 3 in P24 TR

The Zoro Select Quick-Change Sand Disc measures 3 inches in diameter and uses a TR quick-change system for fast swaps. Each pack contains 50 discs made with aluminum oxide abrasive on a polyester backing rated at weight Y. The extra-coarse P24 grade suits aggressive material removal on metal or wood surfaces.

Capacity and headroom: P24 grit and 30,000 RPM limit

The P24 grit provides rapid stock removal for heavy grinding, weld blending or paint stripping tasks. Discs are rated for a maximum operating speed of 30,000 RPM, giving headroom for most right-angle die grinders. The polyester Y-weight backing resists tearing during high-pressure applications but will wear faster than finer grits on finishing passes.

Practical limits of the TR quick-change interface

The TR attachment locks the disc securely for high-speed use yet allows tool-free changes between grits. Maximum speed is capped at 30,000 RPM, so the disc must not be run on tools exceeding that limit. The 3-inch diameter restricts reach on large, flat panels compared to larger discs. Buyers needing finer surface preparation or larger coverage areas will need different grits or disc sizes.

Questions about this item

Will the TR quick-change system on these 3 in discs fit the TR holder I already use on my angle grinder?

Yes, the disc uses the TR quick-change system which matches standard TR holders on compatible tools.

How can I confirm the disc is running at the correct speed after mounting it?

The maximum operating speed is 30,000 RPM; run the tool within that limit and check for smooth vibration-free operation.

What comes in the package and do I need to buy a backing pad separately?

The box contains 50 coated aluminum oxide discs with polyester Y-weight backing; a TR backing pad or holder is not included and must be purchased separately.
