Questions about this item
Will the 1/2in reduced shank fit my 1/2in drill chuck?
Yes, the 1/2in reduced shank is designed to fit a standard 1/2in drill chuck, allowing the 53/64in bit to be used in drills that cannot accept a full-size shank.
What is the correct way to install this Silver and Deming bit so it does not slip?
Open the chuck jaws wide, insert the 1/2in reduced shank fully until the flute begins, then tighten securely on the flat shank surfaces — not on the flutes — to prevent spin-out.
