Introduction
When it comes to creating threaded holes in metal or other materials, it is important to use the correct size tap drill. This is especially true for 1/4 NPT (National Pipe Taper) taps, which are commonly used in plumbing and other applications. In this article, we will provide a comprehensive 1/4 NPT tap drill size chart in PDF format, along with some additional information on how to use it effectively.
Understanding NPT Threads
Before we dive into tap drill sizes, it is important to understand the basics of NPT threads. NPT threads are used to create a sealed connection between two pipes or fittings. They are tapered, which means that the diameter of the thread decreases as it gets closer to the end of the pipe.
When using an NPT tap, it is important to match the tap size to the size of the pipe or fitting being threaded. For example, a 1/4 NPT tap is designed to create threads that will fit onto a 1/4 inch pipe or fitting.
