Can meat grinders really grind bone?

So you want to know if an electric meat grinder can grind bones, the answer is YES! They can only grind bones that are considered soft which are all the bones from chicken, duck, other small fowl and rabbit. Turkey is considered a soft bone but is more dense and only certain models of grinders are tough enough to handle the bones from turkey. Pork, Beef, Lamb and Venison are all considered hard bones.

When grinding bones you want to use a minimum of a 3/8" hole size for the first grind then you can do a second grind using that same plate or a smaller plate to get your finished bone size.

The meat and bone should be very cold and NEVER frozen which would be like sending a rock into your grinder. If you find that you are seeing a grey type substance in your grinder head or showing up in your ground meat rest assured this isn't grease, it is generally burnt fat that has spent too long in the grinder head. Simply clean out the grinder head, make sure the grinder is assembled correctly and make sure the the meat is very cold.

Models of meat grinders which are warrantied for doing bones:
