They’re common and look like most of the hand taps you’ll see around. These thread taps have a spiral cut with relief grooves. Spiral Point Taps (Gun Nose or Bull Nose Taps)

These are the types of taps you should choose from for CNC applications or for manual machining work. Check to be sure what you’re getting and using. Some vendors call these “Second Taps” and refer to Bottoming Taps as Plug Taps. Unfortunately, terminology is not always consistent. Plug Taps are in between Bottoming and Taper Taps because they have 3-5 threads tapered, which is more than a Bottoming Tap and less than a Taper Tap. It’s desireable to thread most of the hole with a Taper Tap first, and then finish the bottom of the hole with a Bottoming Tap. Only 1 to 1.5 threads will be tapered.īottoming Taps are useful for threading blind holes. Bottoming TapĪ bottoming tap has almost no taper at the end because it is designed to thread all the way to the bottom of its reach. Taper Taps are the most common types of taps and are typically what you’ll have in a Tap and Die Set. Typically, the first 8 to 10 threads are tapered. There are two types of Hand Taps: Taper TapĪ taper tap has quite a lot of taper to help it ease into cutting threads gradually.

One applicable standard for Hand Taps is ISO 529. You’ll be surprised at how much better taps made for machines work. Buy some good quality taps and try tapping by hand versus the hardware store set of thread taps. Hand taps, typically bought at the local hardware store, are the most common types of taps, but they are generally to be avoided for CNC work.

The threads produced with roll tapping are stronger than cut threads because the grains are continuous and unbroken, and the displaced metal is work hardened. Roll tapping eliminates the problem of chip disposal. Roll tapping is a process which forms a thread in the hole by displacement of the material into the desired size and pitch. Desired thread size and % of full thread are input parameters for the calculator. Calculations are done according to roll form tap drill charts which are given in the Machinery's Handbook.
