Drill tap charts are vital for engineers and machinists. They provide quick and easy reference to the correct drill sizes and tap sizes for creating threaded holes. This guide will explain how to use a printable drill tap chart and provide some tips for getting the most out of it.
Drill tap charts are typically organised by the size of the threaded hole you want to create. The chart will list the corresponding drill size and tap size for each hole size. For example, if you want to create a 1/4-20 threaded hole, you would use a 7/32 drill bit and a 1/4-20 tap.
When using a drill tap chart, it is important to pay attention to the following information:
Drill Size
The drill size is the diameter of the hole that you need to drill before tapping. The drill size will be slightly smaller than the tap size to allow for the threads to be cut.
Tap Size
The tap size is the diameter of the threaded hole that you want to create. The tap size will be the same as the bolt or screw that you will be using.
Number of Threads
The number of threads refers to the number of threads per inch. The number of threads will be indicated by a number followed by a dash and then the letter “TPI”. For example, a 1/4-20 tap has 20 threads per inch.
