Drill Bits: A General Guide To Understand The Basics
Not only tools but the right tool are vital for any work to carry out smoothly. If doctors don’t have the right equipment, patients won’t receive the right surgery. If a painter doesn’t have the right size paintbrush, the painting would not be so minutely beautiful. Just like that if the workers on the construction site don’t have the right drilling tools, the finished work will not contain quality work. Therefore, here you are going to learn some of the basics about drill bits and drilling tools.
Primarily drill bits are cutting holes that create holes in something/some material. Therefore, it is of utmost importance to choose the right drill bit for the work, otherwise, the work will be messed up. Since soft materials get teared up easily, no specific type of drill bits is necessary. But hard materials are laborious and need specific drill bits for application. If you are going to let this tiny information slip from your memory, it might destroy the drill bit itself or the work will be undone till the deadline also.
What you must look for when scrutinizing the bit is the distinguishing material that is used for designing the bits, the coating is done on it, its size, and the tip’s angle.
For different usage there are different drill bits like High-Speed Steel (HSS) Bits also called twist drill bits. Brad Point Bits also known as W-point tips suitable for application into wood and plastic. Masonry bits are carbide tipped bits used on bricks, concrete, and stone. Multipurpose bits are used in every material like ceramic tiles, metals, masonry, and plastic. Titanium Nitride HSS Bits is coated with titanium nitride that extends the lifespan of the drill bit by reducing heat buildup and increasing bit’s lubricity. Cobalt HSS bits are used to penetrate in stainless steel, high tensile steel, bronze, cast iron, and weld seams. Other bits are Reduced Shank HSS bits, HSS Rivet bits, Spade bits, Auger bits, Forstner bits, Countersink bits, Drill/Countersink bits, Self-centering bits, Spearpoint (tiles and glass) bits, Step drill bits and many more.
Low carbon steel built bits are suitable to drill into softwood whereas high carbon steel built bits for the hardwood. Don’t forget to do sharpening after 4-5 uses. For the soft metals, high-speed steel bits are fitting. They are also good at heat endurance as well as high-temperature performance.
For the tough materials like stainless steel, aluminium, and other industrial work, cobalt drill bits are recommended. With its feature of high heat resistance capability, the cobalt bit performs the work more efficiently and precisely. But don’t be careless with its operation. HSS Cobalt Drill bit is fragile and stiff at the same time, the wrong usage might break the bit or damage the work. Therefore keep the speed under check.
The hardest material is the Carbide tipped bit to cut into harder metals. Its life span is long and can drill a hole through masonry as well as cured concrete.
After material, the coating is of the utmost importance for the tool to work itself efficiently. The basic coating is the black-oxide coating that increases the lifespan of any drill bit. To make the High-Speed Steel bit corrosion-resistant, the black-oxide coating is used. There are also titanium coated drill bits that are more enduring and tough. This coating helps the drill bits in making holes more precise and perfect by the reduced amount of friction.
There are some of the tips shared for every worker who is going to perform the drilling with drill bits. The speed must be slow in penetrating the hard surface in contrast to a fast speed on soft surfaces. As the hole gets deepened, reduce the speed and pressure of penetration. Always apply cutting fluid to smoothen the operation into the surface. Inspect the sharpness of the bit tip point and let them cool naturally. Don’t start work without wearing protective gloves and goggles.
