An iPhone App capable of calculating the exact diameter of drill required for precise thread-creation operations has been developed by Sheffield-based cutting tool specialist, Dormer Tools.
The ‘Dormer Tools Threadsize Calculator’ has been designed to help engineers and machinists quickly and accurately select the optimum drill diameter needed to create a thread.
Thomas Junfors, senior project manager at Dormer Tools, says: “There are formulae that can be used to calculate the recommended tapping drill diameter, but as there are numerous different types and standards of taps available, the recommended dimensions can vary, so it is crucial to get this right. The App takes the user through each of the various steps and factors to calculate the right diameter for you.
“The user inputs the size of their desired thread, selects the process and relevant standard and the calculator determines the correct drill size.”
Dormer’s Threadsize Calculator is free from the iTunes App store.
