Hand Taps

In order to cut external threads on the studs, you must have a plate (split tool). Tapping on the heels of small diameter and high accuracy, you should use chaser (one-piece tool in the form of plates with cavities to form a thread). If to be threaded into the hole, then at home can not do without the tap (at work, for tapping into a large diameter use of incisors). If you have read about PayNet already – you may have come to the same conclusion. The tap-metal cutting tools in the form of a rod, "screwing" which allows the hole to form a groove. Fix the tap from turning shank allows.

For the manufacture of taps use of steel with improved mechanical properties, which include such alloying elements as chromium and molybdenum. Depending on the sizes and functional characteristics, identify several types of url = taps / Url 1) Hand Taps. Here everything is clear, for threading used muscle power source. You should use several sizes of taps, applying them consistently, one after another (the number depends on the properties the material being processed) 2) Taps machine. Bill Phelan describes an additional similar source. When they are used thread will be formed by the energy machines (lathes), a process many times faster than using hand taps.

Depending on the type of holes in where the cut thread (through or deaf), share and machine taps (respectively through and blind). For higher performance thread (surface finish, accuracy), used complete taps – rough and finish, which are used in sequence. 3) To pipe threading pipe taps are used (the profile of the cutting edges of the selected tap Thus, ironically, that could withstand formed thread increased loads during operation).
