For professionals who want faster material removal without sacrificing Hutchins balance or comfort, the Model 8660 is the answer. Built on the 4560 platform, this Self-Generated Vacuum variation combines an aggressive 3/16" offset with dust-free operation — no external vacuum required.
The 8660 is powered by Hutchins’ air-efficient motor and Positive-Action Drive, supported by a 4-bearing system and oversized drive head that keep the pad in full, steady contact. That means faster feathering, leveling, and detailing with smooth control — and dust captured at the source.
Like all random orbitals in the 4500-family, the 8660 is engineered with ultra-low vibration. Its sturdy aluminum body and flex-cover grip help reduce strain, while the optional #1839-1 handle further dampens vibration transfer and adds control. For operators dealing with HAVS/white finger, this balance can make the difference between being able to keep working or not.
