Air Wet Stone Polisher 4500 RPM with Front Exhaust The GPW-7 has a front exhaust port that allows the user to dry the edge of their stone polishing project as they work and to inspect their progress as they go.

I only recently got around to using the tool, and it was on the verge of seizing up after about 20 hours of continuous use. I maintained the pressure between 50 and 90psi and oiled the machine every day of use for the 15-hour period (probably about 5 days). The machine runs for a short period of time and then slows down, I’m assuming because a bearing is on the verge of failing and becoming hot. This thing is a pain in the neck.
