Orca abrasives was founded on the philosophy of providing durable sanding discs with exceptional value. The higher end sanding discs are long-lasting, efficient, but require a substantial initial investment. On the other hand, big box sanding discs are less expensive, but do not last as long so you end up spending more over time.
We have tried so many different sanding discs on the market and were not satisfied with the balance of durability vs. cost. That is why we made Orca sanding discs that fit the high-end sanders. Give our sanding discs a try and see for yourself.
