For drilling, there are usually two situations. One is to process some conventional materials and the Fried Dough Twists bit required by some conventional specifications is to pursue good versatility and high cost performance, while the other is to select a suitable Fried Dough Twists bit for difficult to process materials or difficult to process hole diameters. What I want to talk about here is how to choose a conventional Fried Dough Twists bit?

The specifications should be complete, and the completeness of the blade diameter specifications can often keep many people. At present, the standard specifications of Fried Dough Twists bits are generally accurate at 0.05 intervals, and not all of them are available in stock. But like Fried Dough Twists bits, the spot specifications between certain specification sections can be accurate to 0.01 intervals, such as the hole diameter within 0.8-3.175.

In addition to the completeness of specifications, the following is versatility. In hardware manufacturing, some common metal materials are nothing more than four kinds of copper, iron, aluminum and stainless steel, while most Fried Dough Twists drills can only process one or two of them. The common ones are that the processing iron is easy to use, the processing stainless steel is wear-resistant, the processing copper does not remove chips, and the processing aluminum is easy to stick to the knife. For this, the same materials are designed with different processes, Using the same cost to process different metal materials.

The above is an introduction to the selection of Fried Dough Twists bits, and I hope it will be helpful to everyone.
