Tackle every sanding, grinding, and polishing task with this comprehensive 50-piece 2-inch (50mm) quick change roll lock sanding disc set. Featuring premium aluminium oxide abrasive grains and a heat-resistant, anti-loading coating, these discs deliver fast, consistent material removal across a wide range of surfaces — from rough shaping with P24 all the way to fine finishing at P320.

Key Features

• Premium Aluminium Oxide Abrasive: High hardness corundum grains with an Active Grinding Aid coating prevent loading and minimize heat buildup, extending disc life and maintaining cutting efficiency throughout each job.
• Quick Change Roll Lock Design: The unique safety torque screw mechanism allows fast, tool-free disc swaps, keeping your workflow moving without interruption. Strong wear resistance and aggressive grinding force mean fewer disc changes overall.
• 10 Grit Options in One Set: Includes grits P24, P36, P40, P60, P80, P100, P120, P180, P240, and P320 — from heavy stock removal to ultra-smooth finishing, all in a single kit.
• Versatile Compatibility: Fits most standard rotary tools including orbital sanders and electric drills. Ideal for metal, wood, plastic, jade, non-metal surfaces, and smoothing welded seams.
• Anti-Clogging & Heat-Resistant Coating: The specially treated surface resists thermal buildup and disc clogging, improving both grinding efficiency and overall service life.

Frequently Asked Questions

Q: What grits are included in this 50-piece sanding disc set?

A: The set includes 10 different grits — P24, P36, P40, P60, P80, P100, P120, P180, P240, and P320. This range covers heavy material removal (P24–P40), general sanding (P60–P120), and fine finishing or polishing (P180–P320), making it a truly versatile kit for any project.

Q: What tools are compatible with these 2-inch quick change sanding discs?

A: These 50mm roll lock discs are compatible with most standard rotary tools that accept a quick change (roll lock) mandrel, including orbital sanders and electric drills. They are suitable for sanding and polishing metal, wood, plastic, jade, and non-metal surfaces, as well as grinding and smoothing welded seams.

Q: How does the quick change roll lock mechanism work?

A: The roll lock system uses a unique safety torque screw design that lets you snap discs on and off your mandrel quickly without extra tools. Simply push and twist to secure the disc, and reverse the motion to remove it. This speeds up grit changes and reduces downtime during multi-stage sanding projects.

Q: How do I get the longest life out of these sanding discs?

A: The aluminium oxide abrasive grains are coated with an anti-loading, heat-resistant treatment to help prevent premature wear. For best results, apply consistent moderate pressure, avoid excessive heat buildup by keeping the tool moving, and progress through grit stages systematically from coarser to finer grits.
