Question: Are all parts of this grinder made of stainless steel?
Document: The steel parts are well made and the grinder works great! Less work than my trusty old hand crank grinder too.However, that cheap plastic pusher needs a redesign. Mine came cracked, the plastic was so "durable" it couldn't withstand the temperature changes inside the shipping containers.Come on Chefs Choice spend an extra quarter on a better grade plastic.Now ... where is my trusty old wooden push stick?
After getting the mixer, I was in the market for a grinder attachment to make sausage, pate, and other ground items. The reviews for the stock grinder were abysmal and I felt I'd end up with a lousy part and end up returning it. I even went to the local BB&B and looked at the grinder attachment and verified what I had read. Cheap! The cutter was made of punched out steel and the whole thing seemed flimsy. I looked around on-line some more and found this grinder.
This is the first meat grinder that I've ever purchased. I like the fact that, other than the plunger, there are no plastic parts. It attached to my Kitchen Aid without any problems and worked great. I wish the feel tube was a little larger and that's the only reason I went with 4-stars instead of 5. I would highly recommend this model.
At last I have a metal meat grinder that fits my old Kitchen Aid mixer, the one that was made in the USA.The laughable &#34;meat grinder&#34; attachment offered for years by Kitchen Aid is an insult to those who want or need to grind their own meat because it's plastic and doesn't hold up to the pressure of grinding beef for more than one minute. I've had several of these ridiculous units and each one cracked within a minute of starting to grind meat.This aluminum grinder is pretty, well made, and grinds quickly as long as meat is cut into relatively small pieces.
I had no trouble grinding 3 1/2 pounds of round roast in about 5 minutes. I'll be making more meatloaves now that I can grind my own meat.Works nicely for pork and poultry too.The parts go together and come apart easily and quickly. Cannot be washed in automatic dishwasher with lye soap, nor be left soaking in water  with or without detergent -- will pit because it's aluminum -- but it's not onerous to do a quick hand wash after using.I'm looking forward to making my own sausage from now on, too.
We got this to grind and make turkey burgers,sausages,and ground beef. Works great made sausage last week turned out really good.
Made Italian sausage for the first time and will never buy supermarket sausage again! My mixer didn't even strain and I have the ability to choose the grinding speed.
Fits perfect to my Kitchenaid. Very well made and worked wonderful grinding frozen fish to make fishcakes. Easy to clean. Looking forward using it a lot more. Glad I chose &#34;HQ all metal&#34; over the plastic versions.
We are very happy with this attachment. It arrived quickly, and sat around for a long time, waiting for a birthday, and that made me nervous, but when it was presented it was used immediately, and it sparked a lot of creative thinking. ...and I was afraid that it might be as exciting a gift as a mop! A REAL cook will love it, and understand why THIS one is the best choice.
Yes, it's a whole lot more expensive than the O.E.M. part but it's worth every penny! I've made a few batched so far and love it! Just make sure you NEVER put any of the cast aluminum items in the dishwasher and make sure you coat the cutter and extrusion dies with vegetable oil after cleaning them to prevent rust. I really expect to get many years of use out of this product and I'm glad I bought it!
Answer: No, I think they're just plain old cast metal.I do however, think (judging by weight) that the moving parts are hardened steel.
