I had no issues with the shaft length that was supplied. As you can see from my photo and description, the stock photo used along with the product listing and description is a bit deceiving. Overall length: 4-7/16". Thread length approx. 1-1/2". The length from the base of the hex to the end of the thread is approximately 2 inches. Before you modify a threaded diamond core hole saw, get this piece in your hands. If they send you what I received, no modification is required. Well done for the price.
