COMPATIBILITY
Abrasive and tool compatibility
- Match the abrasive diameter or sheet size and attachment style to the exact tool or block.
- Use only at or below the abrasive's rated speed and with the tool's required pad, guard, or dust-control equipment.
- Test the selected grit and process on a small area when the finish system or substrate is unfamiliar.
QUICK ANSWERS
Common questions
Which size should I choose?
Choose among 6", 5", 3". Match the selection to the work and the manufacturer's current instructions.
What arrives when I order one?
One order adds one package for the selected option. The table above shows the exact choice tied to each MPN.
How do I choose the right grit?
Start with the surface condition and the next coating or finishing step. Follow the paint or repair system's grit sequence rather than choosing only by how fast the abrasive cuts.
What should I verify before using 3M™ Cubitron™ II Hookit™ Clean Sanding Abrasive Discs?
Confirm the selected MPN, application, required companion products or accessories, and current 3M instructions before use.
