Tungsten carbide indexable drill bit, also called short-hole drill or U drill, is a kind of high-efficiency drilling tool. In recent years, it has been widely used in various kinds of numerically-controlled machining tools, machining centers etc. This kind of drill bit has two indexable inserts installed asymmetrically, forming inner edge and outer edge which are responsible for the machining of internal holes and external holes respectively. When the hole diameter is relatively large, more blades can be installed.

Tungsten carbide indexable drill bit is suitable for high-speed cutting and has high machining quality and good chip removal property. It can be classified into six categories according to its blade shapes, chip removal groove shapes, structure, machining characteristics and so on.

I.    Being classified into quadrangle, convex trilateral, rhombus, hexagon drill bit etc. according to blade shapes.
II.    Being classified into straight flute drill bit and spiral flute drill bit according to the chip removal grooves.
III.    Being classified into cylinder shank drill bit and morse taper shank drill bit according to different drill bit shank shapes.
IV.    Being classified into solid, modular and split type drill bit according to the structure.

Reins tungsten drop shot weights do everything they are supposed to do. Reins tungsten drop shot sinkers gives anglers an advantage because it is denser than lead sinkers also meaning that it is more sensitive. These tungsten sinkers are also smaller than traditional lead and make more noise when drug across the bottom.

The unique reins tungsten drop shot weights design makes it easier to pull thru rocks, weeds, or brush with fewer hang ups. Reins down shot sinkers are made up of 95% tungsten and 5% nickel alloy making them 1.8 times as dense as lead and environmentally safe. The dense tungsten material allows you to feel every pebble along the bottom making it easier to tell a strike from a nibble.

Anglers who have always been on the leading edge of environmental activism and care choose Chinatungten Online to provide them a safe alternative to lead fishing weights that contains superior fishing attributes, making the terminal tackle choice that much easier in a time of change. Be the angler with the most technologically advanced fishing tackle in the boat with tungsten dropshot weights of Chinatungsten Online as a part of your terminal tackle.

Tungsten carbide end mill is a kind of cutting tool used in thread machining. It was firstly popular in occident, and later, with the development of numerically-controlled machine tools in China, it is also gradually accepted by users in China.

The traditional method for thread machining is normally done by using thread turning tools or screw taps, but now the numerically-controlled machining technology has made it possible to do thread machining with more advanced method, i.e. numerical control milling. Compared with traditional method of thread machining, tungsten carbide end mill machining is of greater advantages in machining precision, machining efficiency, etc. In addition, it is free from the limitation of thread structure and the direction of turning, and thus can be used in the threading of the internal and external threads of different kinds of turning directions.

For those threads that allow no tool withdrawal grooves, it is difficult to do machining with traditional turning method, like using screw taps or threading dies, but easy with numerical control milling. What is more, the duration of tungsten carbide end mill is over ten times larger than screw taps. Also, it is quite convenient to do adjustment towards tread diameter size if an end mill is used in the numerical control milling.
