Hole size for 1 8 npt

Pip's Island Home. Are you looking to tap pipe? The first step you must take is to drill the right size hole before tapping threads in your pipe. But, not just any drill tip will do; you must choose the correct one to ensure accurate pipe threads that will provide a tight seal. Matching the drill bit to the tap size is only the first step; you need to follow best practices for drilling and tapping to ensure a job well done. I have included some drilling and tapping tips that will come in handy especially if you are new to these pipe cutting techniques. A pipe tap is a tool used to create threads inside a pipe during pipe fitting and machining applications. Threading the interior end of a pipe creates a receiving female pipe into which a male pipe is inserted to join two pipes, creating a tight seal. Also known as threading taps, pipe taps are made from steel alloy or some type of hardened steel, making it harder than most metal pipes. The design of a pipe tap will vary from one manufacturer to another. Some taps are manual with one end acting as a handle while the other end features cutting grooves. With manual taps, the threading process involves cutting by hand. More modern tapping tools are built with one end featuring a lug or nut while the other end is used for tapping. This design allows you to fit the pipe tap into another hand or powered tool that helps to turn the tap, making the process less manual.

First, make sure that your drill bit is very sharp. A dull bit will make it harder to get a clean cut and can potentially damage your workpiece. Second, be sure to lubricate the drill bit with cutting oil before beginning to drill. This will help keep the bit cool and prevent it from overheating. Finally, take your time and go slowly when drilling.
