Tungsten carbide drill is also known as tungsten carbide brill bit that has excellent characteristics such as high hardness, high wear resistance, high toughness, high strength, and long service life. The specially designed edge of the drill bit is sharp and durable to suppress chatter during processing and improve the quality of the processed surface. Also, it reduces cutting resistance and improves working efficiency to obtain good surface finish.

Tungsten carbide hollow drill, which is called annular cutter when it is used in metal, is a drill specifically designed to remove a cylinder of material, much like a hole saw. Tungsten carbide hollow drill bits are used for many applications, either where the core needs to be preserved, or where drilling can be done more rapidly since much less material needs to be removed than with a standard bit.

Tungsten carbide core drill has characteristics of high drilling efficiency, low cost and labor saving, and is mainly used for drilling of steel components in rail transportation, bridges, ships, machinery manufacturing, aerospace and other fields. Well, what are the installation precautions of tungsten carbide core drill bits?

Tungsten carbide core drill can be a cost effective means of drilling through softer unconsolidated formations. And such a core drill is applicable to hole cutting and process of annular groove on various magnetic drills and press. Tungsten carbide does not possess the hardness of diamond, while it is relatively cheap compared with diamond drill. It cuts effectively at low r.p.m. (revolution per minute) and low weight on bit.
