The advantage in every pass
Fast material removal that stays productive.
The ceramic-hybrid grain fractures under use instead of simply wearing smooth—helping maintain cutting action from rough leveling through finish prep.
Self-sharpen while you sand
The grain continually fractures to expose fresh cutting edges instead of simply wearing smooth.
Keep useful cutting performance longer
Consistent cutting action means less time reaching for a replacement disc.

Call 1-800-900-GLUEExactly what is included in the promotional bundle?
You receive two 50-disc Z9 multi-grit packs—100 discs total—plus one Starbond Knot-Filler System at no added charge. Each 50-pack contains 20 discs in 80 grit and 10 each in 120, 180, and 240 grit.
What comes in the free Knot-Filler System?
The system includes black and dark-brown medium-thick CA glues, a 6 oz aerosol accelerator, and application accessories for filling cracks, knots, and small wood voids.
What sanders do the bundle discs fit?
The promotional discs are 5-inch, 8-hole, hook-and-loop discs for compatible random orbital sanders. Confirm the pad diameter and hole pattern on your tool before ordering.
Can I add a 6-inch pack to the same order?
Yes. The separate 6-inch section can add a compatible 50-pack with the promotional bundle. These 49-hole discs require a compatible 6-inch sander and do not fit the 5-inch, 8-hole sanders used with the bundle.
Can I use Z9 discs on materials besides wood?
Z9 ceramic-hybrid discs can be used for many sanding and surface-prep jobs, including wood, metal, coatings, and automotive work. Always match the grit, pressure, speed, and dust extraction to the material and finish.
What is Starbond’s return policy?
Eligible items may be returned within 30 days under Starbond’s current policy. Review the full shipping and return terms before ordering.
