This number we will subtract from the outer diameter (0.250). Therefore, our required diameter of hole is: 0.250 - 0.0325 = .2175 inches. In addition, we need to check if the pitch is too coarse for the diameter. The minimum diameter possible for the chosen pitch (x) is: Threads per inch. Double thread depth.

As an industry leader in the field of whirling technology, Leistritz has developed an innovative solution to machining difficult internal threads. The process, which is called "internal whirling," can be performed in both soft material using carbide tooling and in steel as hard as 65 hrc with CBN.
The inner diameter of thread grinding with better processing economy is usually 10-525mm. The rule of thumb for grinding deep hole internal threads is that the ratio of the length to the diameter of the grinding wheel shaft does not exceed 7:1. The challenge in grinding deep-hole internal threads is the mutual constraint between the …
