Step 3: Cheese Grater Attachment
Then insert a 1/4" bolt through the drilled hole with the head of the bolt on the inside of the grater. The length of the bolt isn't critical. It just needs to be long enough to stick out past the end of the handle by at least 1/2". Then tighten a 1/4" nut onto the outside of the bolt and reassemble the cheese grater. Just attach the drill to the exposed bolt and you have a power cheese grater. If the bolt spins free of the handle during use, you need to tighten the nut more firmly until the handle and bolt spin together.
With your power cheese grater, you can make a mountain of freshly grated cheese in seconds.
