Drill bits are some of the commonest industrial and home mechanical accessories
. They are used to make bores or scoop out some materials from wood, metal, or other workpieces. The rule of the thumb when selecting drill bits is that the bit should be harder than the material being drilled. The drill bits fall into several categories. 1) High-Speed Steel (HSS) Bits: This category of drill bits, also referred to as twist drill bit, is one of the common models used in everyday plastic, wood, and metal related works. They mainly have cylindrical shanks although there are some modified to a ¼ inch hex shank. 2) Multi-purpose bits: These bits are designed with special tips that are made of diamond and strengthened with tungsten carbide. This makes the bits ideal for both rotary and hammering operations. They can be used for drilling nearly any type of material including metal and ceramic tiles. Others include titanium nitride HSS bits, cobalt HSS bits, and Reduced shank HSS bits. To see the full list of drill bits, make sure to visit our site.
