Drill bit is one of tools which very commonly used by people as a home tool shed. Drill bit can drill on many materials such as solid wood, porcelain, glass, and metals. Drill bit is created from kinds of different materials, depending on needs. The materials come from very hard material such as carbide, and more fragile than steel. The main aspect of drill bit selection is the material of its drill bit. Not all drill bit is suitable on every object materials. It is very important to understand about the matching object material and drill bit material to ensure and to create best result.
There are many of metals which is used to produce drill bits. Each material is appropriated with a specifically types of surface. Understanding about strengths and weakness are very important to choose the drill bit on any projects.
• Low carbon steel
Low carbon steel is very suitable for softwood. It is too soft to drill harder materials. To increase the agedness and quality of drilling, low carbon steel need to be sharpened. Talking about price, this drill bit material is relative cheap.
• High carbon steel
The difference of high carbon steel and low carbon steel is high temperature tolerance. High carbon steel has higher temperature tolerance, it means that high carbon steel can be used on higher drilling speed. Factually, this bit assures to keep the fundamental of integrity longer.
• High speed steel
High speed steel or HSS drill bit is made from very hard carbon steel which has higher heat resistance than high carbon steel. This kind of drill bit material can be covered to increase the quality. This material drill bit is completed with porous surface holds coatings well.
This is specialized on hardened steel bit. This material has ability to keep the heat rapidly and tolerate the materials from heat. This material is fragile, so it is important to care of it. It has vulnerability to chip and brittle. Carbide is acceptable for drilling hard wood and metals.
Cobalt drill bit is very hard. It can be used to drill on extremely hard materials in standard high speed such as stainless steel and thicker metal surface. Cobalt is resistance from the heat damage, it is one of the advantages using this drill bit. The most important thing that cobalt is very prone to brittle and unexpectedly damage.
• Diamond drill bit
Diamond drill bit is the hardest material. This is created from coating carbide on diamond particle. Notice that there is very important thing which diamond drill bit is not acceptable for drill metal, soft wood, plaster, or soft plastic. It causes drill bit to clog up because the materials are too soft.
