How To Identify The Pros and Cons of Taps？

There are many types of taps on the market, such as Hand Taps, machine taps, stainless steel taps, etc. Due to the different materials used, the prices of the same specifications are also very different, making buyers look at flowers in the fog, not knowing which one to buy. The following teach you a few simple methods:

Hand Taps

Method:

1. Check whether the thread at the front end of the tap groove is evenly ground and whether there is a quick cut at the cutting edge. The good ones are in a positive 7-shape, and the bad ones are in the inverted 7-shape or U-shape (when the tap is withdrawn, it will cause two cuttings, which is easy to break. And it affects the accuracy of the thread

2. Detection of heat treatment: whether the drawing tap is parabolic (about 5 meters) into the air and falls flat, indicating that it is brittle.

3. Knock off the tap to see if its fracture is obliquely long, and the grains in the fracture are finely knotted, indicating that the heat treatment and material are good, flat or obliquely short, and the coarse grain is not well measured.

Precautions

The quality of the tap mainly depends on its original material, heat treatment, geometry, precision, equipment, speed and processed material, hardness, the quality of the operator, etc., how relevant! When selecting taps, pay special attention to the original material, heat treatment, and geometry of Professional Taps. For different machining holes, it is recommended to choose different types of taps!

In actual operation, the grinding of the cutting edge is very important, especially for stainless steel series, which can be divided into cutting and lengthening of the guide. The cutting edge should be ground to a lower angle to increase the strength of the tap. At the same time, cooling and lubrication are required. Keep up, the service life of the tap is relatively long! In short, we are dealing with specific situations concretely.
