has it steel internal gears or plastic one?

I had the gear box apart. The several gears are either nylon or metal. High speed shaft from motor is metal but the gear that meshes to it is nylon (plastic). This is common with cheaper grinders and not necessarily negative unless you are a commercial operator.

Steel. This is by far the best grinder I have ever seen for the money. It just might not be for you. Great deal.

Metal now. It was previously plastic, but they redesigned it. I bought the new (metal triggered) unit about a week ago. I recommend it without reservation.

I'm not positive...but I think one has a "twin gear" made of stainless steel?, and This one has a single made of solid plastic. They both preform the same "masticating" action. Hope this helps.

It is steel but appears to have some type of coating. Not plastic though. There is no plastic in the interior at all. It almost feels and looks like a Teflon type coating. Very thin coat that I'm sure is meant to prevent rust.

I believe it's steel, but suggest you contact the manufacturer to confirm that.

Wondering the same thing? Does it still have the cheap plastic gear that breaks or has it been updated?

The one I got is steel. I'm guessing they started making them out of plastic and switched to steel for obvious reasons.

The gears are plastic. There should be no issue with corrosion. The only metal part is the axle, which passes through the gearbox to turn it.

Combination. The inside parts are metal, like the gears and such. The top is plastic.

both, but its metal where it counts. the teeth and ratcheting mechanisms are all metal with a plastic overwrap

Be Careful, they sell a model with plastic gears. If you are buying one, make sure the ad says METAL gears.

It's all plastic, except the blades are steel or metal. Either way it works fine

I didn't notice a warranty. All I know is I fixed two garage doors with this. I think they make this part to fail on the garage door opener. The gears inside the motor housing are plastic and the chain gear is metal. I found it to be a lot cheaper and easier then changing the garage door opener. I have an extra just in case a friend needs one

It appears to be plastic. At least its not a ferrous metal as has no magnetic attraction. The only surface parts that are magnetic are the sole plate and chromed "nose" piece at the front. Iron has been used for several months and the lever in question remains fully functional and unblemished.

The gears are enclosed in a plastic sleeve. I'd guess plastic, but I cannot tell. Do NOT purchase this product until you've read my earlier comments on the opening/closing door not closing!
