6" Hookit Multi-Hole Blue Sanding Discs - 500 Grit (50 per Box)

Blue is the ideal boatyard abrasive for paint and filler — it stays sharper so it runs cooler, cuts fast, and provides a consistent scratch profile. Blue abrasives save you time and money with longer life, fewer disc changes and less re-working.

Blue abrasives' engineered ceramic mineral blend delivers best-in-class cut and life. The anti-loading design and the universal multi-hole pattern boost dust extraction.
The overall result is extended disc life, improved productivity and a cleaner work environment.

3M™ Blue Abrasives are constructed with a blend of premium aluminum oxides and long-wearing synthetic ceramic mineral abrasive particles that cuts through paint and body filler with consistent results every time.
Use the coarser gades for repairs and working with body fillers.
Use the finer grades for featheredging around repair areas as well as for primer sanding when prepping for paint.

New Multi-Hole Pattern captures dust to reduce loading and also improves vacuum dust extraction over 6 and 7 hole patterns. The Multi-Hole Pattern also significantly extends the life of the disc.
Hole pattern matches that of Festool Disc Pads.

• Premium mineral package stays sharp - so it gives consistent performance for the life of the disc
• Sharper mineral particles cut faster with no plowing - so the disc runs cooler and minimizes surface heat damage
• Stearate coating further reduces loading for improved performance
• Upgraded bonding resins improve durability
• Improves dust extraction efficiency compared to 6 and 7 hole patterns
• Special guide holes in the disc allow for alignment with the majority of dust extraction back-up pads

The Blue Abrasives Series is 3M's premium mid-tier abrasive.
If you desire higher performance discs, consider 3M's purple Cubitron II abrasive discs.
A more economical alternative would be 3M's lower performance Green Corps or Gold aluminum oxide discs, but these offer only a very modest price benefit and are better suited for grinding or wood sanding applications, respectively.
