Sizes: 2" (50 discs per pack) or 3" (25 discs per pack)
Materials: Aluminum Oxide (36–120 grit) or Ceramic (24–120 grit)
Fitting: Type R, male-style — fits standard Rolloc quick-change holders
Best for: Grinding, deburring, and blending in tight spaces

Aluminum Oxide vs. Ceramic — Which Should You Choose?

Material	Best For	Grit Range
Aluminum Oxide	Softer metals like aluminum; general-purpose sanding	36, 60, 80, 120
Ceramic	Fast, long-lasting cutting on stainless steel and steel — comparable to 3M Cubitron II	24, 36, 40, 60, 80, 120

2" vs. 3" — Which Size Do You Need?

2" discs are ideal for tight, detailed work — inside corners, small welds, and confined spaces. 3" discs cover more surface area per pass, so they're a better fit for general grinding and blending where you don't need to get into tight spots.

Frequently Asked Questions

What's the difference between Aluminum Oxide and Ceramic Rolloc discs?
Aluminum Oxide is a solid all-around choice for aluminum and softer metals. Ceramic grain cuts faster and lasts significantly longer on stainless steel and steel — it's built for heavier, more demanding work.

What does "Type R" mean?
Type R refers to the male-style twist-on fitting, which is the standard connection for Rolloc-compatible tool holders.

What sizes are available?
2" (50 discs per pack) and 3" (25 discs per pack).

Can I use these on stainless steel?
Yes — ceramic grit Rolloc discs are specifically built for fast, long-lasting cuts on stainless steel and steel.

How many discs come in a pack?
2" packs contain 50 discs; 3" packs contain 25 discs.
