The 6 Best Jet 8 slow Speed Bench Grinders (2023 reviews)

The jet old grinder's material feels more premium than its price would suggest. THIS IS THE BOMB REALLY WELL BUILT. It holds its own during large industrial projects. It is designed to run at 60hz and slowing it down would slow down the cooling air flow for the motor, add that with a load (grinding application), the motor may not be able to cool itself sufficiently. The motor is powerful enough to sharpen mower blades and not bog down. It is very heavy, doesn't vibrate, and starts up to full speed fast.

The grinder is rated at 6.25 amps, 10 amps would work fine, breakers are rated in amps, not watts, and light bulbs are rated in watts. It is definitely high quality.

Why We Like This:

Plenty powerful and does the job well
Very impressed with cast iron wheel guards and tool rests
Starts immediately and comes to full speed within 1 second
Extremely quiet yet smooth and powerful

Best For resin: Jet Great Grinder

Buy on Amazon

Best part: jet great grinder costs comparatively low and it is available to ship in 24 hours. This machine is very rugged and the wheel guards, tool rests and eye shields are all very steady and vibration free when in use. It is perfect for resin bonded, chlorinated, mechanized, and silicone carbide grinding wheels. It has a very good bearing and it takes a while for it to spin down. The ball bearing shaft runs very quiet and there is no wobble in the stone wheels. The motor is plenty beefy to handle even heavy handed grinding. An optional light that is as rugged and practioal and vibration free as the grinder would be a welcome addition.

It is great for metal, not for wood tools.

Why We Like This:

You can also get buffing wheels and wire-brush wheels
Nicely built grinder could use a little more power
Lots of momentum and power means extra time to stop
