Identification of the Iron Bits and their Applications in the Various Industries

Identification of the Iron Bits and their Applications in the Various Industries:

Given the widespread use of iron in various industries, the use of iron bits for various purposes is common. With the help of iron bits, it is possible to drill the metal materials. By employing iron bits, it is possible to create holes of different depths and diameters. Holes created by iron bits are circular in shape, and in specific cases, bits are designed to create holes in shapes other than circular.

Review of the Iron Bits in terms of Structure and Materials:

Iron bits and metal bits, based on the shape of their connection to drilling tools, are either in the form of straight shank or tapered shank and are used for different types of machines. The straight shank type is more commonly used and is connected to a drill by a three-jaw chuck. The tips of tapered shank bits are conical and are used in special holders of drilling machines such as lathes or pillar drills.

The base metal used in these bits is iron, with the addition of other materials such as carbon, cobalt, chromium, tungsten, molybdenum, etc. Iron bits must not only be strong and durable, but also have some level of flexibility to prevent breakage. To achieve this, adding MOLYBDENUM is included in the manufacturers’ production orders.

Tungsten increases the heat resistance of the bit; it is worth noting that the high rotational speed of the bit generates a lot of heat, which is why tungsten is necessary. Carbon increases the strength of the bit and sharpens its cutting edge. Chromium also increases the strength and resistance against wear.

● Constituent Materials of Iron Bits:

Iron bits can be divided into various categories according to their material, and they have different usages.

● Regular Bits:

Regular bits are suitable for mild irons and are not effective for other types of iron. These bits can significantly increase the working time during the drilling and can often break or burn during work.

● HSS Steel Bits:

High-speed steel (HSS) bits are used for steel, soft steels, hard irons, hard woods, etc. HSS bits are commonly used for high-speed drilling and are referred to as multipurpose bits. These bits are not suitable for creating holes in harder materials such as granite and quartz.

● HSS Cobalt Bits:

HSS cobalt bits have a higher percentage of cobalt compared to other bits. While the higher concentration of cobalt increases the brittleness of the bit, its advantages, especially in specific cases, are significant. Higher cobalt content leads to increased durability and improved quality of bit edges, enabling high-frequency hole drilling in hard materials.

Tungsten Carbide Bits:

Tungsten carbide bits and other carbide bits are highly resilient and are suitable for drilling through various materials. Carbide bits are also suitable for creating very fine holes with diameters less than a millimeter. For example, they can be used to create holes in electronic circuit boards.​

Various Types of Iron Bits in terms of Manufacturing:

The various types of iron bits in terms of manufacturing can be set in two categories. The first one is the roll-forged iron bits which for making them we must bend the hot metal and the change the same in the form of bits. Such method of manufacturing may reduce the bits strength.

The second method's name is making the foley-grand iron bits which they can be shaped into the bits and drills in the process of bits production. Due to the lack of applying the heat in the foley-grand method, the bits structure shall be very stronger than the bits produced in the roll-forged method. 

The iron bits are of the various types in terms of length and diameter. Invariably and most of the times the length of various types of iron bits remains standard but there are also some bits with the lengths of so-called long and or super long ones for the special consumptions. The diameter of an iron bits starts from one millimeter and then continues for the higher diameters. Some of the iron bits are of the decimal numbers which are called the tenth bits or drill.   

  Step Drill Bit:

Such bits and or drill is one of the various types of bits which provides us with the possibility of creating a big hole through starting from a small one with regards to the staircase shape of bits. Also, this reduces the need for changing the bits repeatedly. Furthermore, the foregoing bits shall be also deemed useful for the big holes.

Hole Saw:

Such tool is one of the various types of drills and bits which are among the too much used ones and that is applied in the huge industrial consumptions and small industries such as the construction industry of the residential complexes. For example, the place for installing the various lamps in the ceiling can be drilled by the use of such drill or at the time of installing the fittings or the works of installation.

The gimlet auger is a tool that which provides us with the possibility of drilling work for the different sizes. The remarkable point here is that can do the drilling action easily and with the various diameters. With regards to the shape of such drill, more energy is not applied for the drilling and this job can be easily done. The hollow cylindrical gimlet auger acts like a slender cylinder which is of the serrated and jagged edges. The angle of saw shaped dents in the gimlet auger is about 60 degrees. Type of the blade applied in the gimlet auger has been made out of different materials. The drills with the carbon steel blades are known as an appropriate option for the general and construction consumptions.

Bi-Metal Hole Saw:

Such drills are of the more powerful structures and they also involve the M42 high-speed steel alloy with 8 percent of cobalt which are appropriate for drilling the metals, hard woods, plastic or works which are done continuously and in the long run. Such drills are able to create holes until the depth of 42.5 millimeters.

The tungsten carbide is another cover which is used for the gimlet auger blades. These drills are useful for the industrial purposes and are able to be used and applied continuously and in the long run.

TCT & HSS Hole Cutter:

The TCT hole cutter can be used for drilling the hard steel, steel and titanium and …..and it has a very good ability. This drill is of the high-speed steel type (HSS). Having enjoyed the magnetic property in the base of such drill may cause a relatively easy usage therefrom in the different occasions.  

Final Words on Identifying the Iron Bits and their Applications in the Various Industries:

In this article, we have discussed the identification of iron bits and their wide-ranging applications in various industries. Due to the diversity of the materials and construction of iron bits, they are categorized into different types, each designed for specific uses. Iron bits, owing to their diverse materials and structures, are used extensively in various industries.

Drills come in various classifications due to the diversity of material and substances, each designed for the specific applications. Regular drills are suitable for drilling into softer iron, whereas High Speed Steel (HSS) drills are the preferred choice for metals and hard materials. Tungsten carbide drills, known for their high hardness and corrosion resistance, are used for creating fine and small diameter holes. Additionally, cobalt-enhanced HSS drills, known for their durability and improved wear resistance, are used for drilling in hard materials. This diversity in materials and structure has made these tools diverse options for various industries.
