14-24 SPECIAL PITCH HAND PLUG TAP14-24 SPECIAL PITCH HAND PLUG TAP 5-750-1218, BRIGHT, HSS All our special taps are made of High Speed Steel, are a bright finish, and we normally stock a Plug Style, Bottoming Style may be available in some sizes. For drill sizes on taps most manufacturers recommend 70 to 75 percentage of thread. For standard fractional threads the MAGIC NUMBER IS .9742! FOR EXAMPLE let get a drill for a 1/4-20 tap; 1) Divide .9742 by the pitch, which in this case is 20 & you get .0487. 2) Subtract .0487 from major tap diameter, in this case .2500. 3) The answer is .2013. 4) Round up or down to nearest drill size, which is a #7 drill (.2010). The larger the drill, the less stress you have on the tap, and the less breakage! Don't see the tap you need? We can get any tap made within 24 to 48 hours, ask your salesman for details!
