Most DIYers understand the importance of using the right tool for the job. While people can spend hours studying which drill to buy, they often overlook what will come into contact with their work material: the drill bit.
Choosing the right drill bit means conserving your most valuable resource: time. Therefore, for maximum efficiency, learn about the different types of drill bits and know which one is best for you.
Understanding drill bits
Drill bits are vital for many DIY projects around the home and workplace and are used by a wide spectrum of experts and DIYers. They are used by electricians, carpenters and plumbers to make holes for wiring, plumbing and carpentry.
Do-it-yourselfers use drills to connect large items, such as flat-screen TVs or shelves. However, if you have the right drill and bit, you can drill through the center of the brick wall to run the cable out. Be sure to cover the hole when you finish running the cable.
Luckily, it’s easy to buy drill bits in Australia. With the use of the Internet, you can access reputable online stores. This allows you to browse their seemingly endless catalogs from the comfort of your home. So if you can’t leave the house to go to a hardware store, you can have the drill bits delivered to your door! Easy, right?
Types of drill bits
Is it necessary to have specialized bits when multi-purpose bits will suffice for most projects? The solution depends on two main criteria. First, consider what type of project you are going to work on. Second, consider the drilling material. A multi-purpose drill bit will be sufficient for basic tasks such as drilling small holes in walls or wood.
However, many projects are more complicated. For tougher materials and more rigorous drilling, you’ll want to choose bits designed specifically for the material you’re working with. Using the wrong bit is never a good thing. To know more about the types of drill bits, read more.
Masonry Drill Bits
Masonry drill bits are used for a variety of tasks. They have the right power to drill through brick, concrete, stone and thick tiles. Its tungsten carbide tip is attached to a twisted shaft. Most masonry bits are designed for use in hammer-action power drills. However, if the movement is too intense, cheap and poor quality parts can break. Always use high quality drill bits and avoid excessive pressure or speed when drilling.
For harder materials, a slower rotation speed is preferable. This will prevent the tip from getting too hot. To prevent dust buildup, you should remove the drill bit frequently. Various sizes and lengths are available. Do not drill deeper than the drill bit slots; it will get stuck in the hole. Long pieces are ideal for use on walls.
Safety Data Sheet (MSDS)
When drilling masonry, SDS bits are undoubtedly the gold standard. These pieces are mainly used in concrete. They are grooved and have a tungsten carbide tip. SDS are designed for use in rotary hammer tools. Various types range from standard to industrial. Standard bits can penetrate clay bricks, fire bricks and concrete, while industrial bits can penetrate lintel and hard masonry.
Spin
Most people picture a twist drill when they think of drill bits. They are quite ubiquitous and should be in any home DIY enthusiast’s toolbox. Many contain multi-purpose bits for use in wood, stone, and plastic. Others are designed for use with concrete and metals.
The tip helps cut through material, while the twisted design helps remove debris as the drill passes through the material. These pieces are available in various sizes, from extremely small to extra large. Carbon steel is used for standard wood drill bits, while high speed steel (HSS) is used for metal, masonry, and other tough materials. If you are drilling metal, use an HSS drill bit.
hole saw
Hole saws are round in shape and have a hollow interior. They are designed to make huge holes in wood and plastic. Depending on the type, they can cut to a depth of 48 mm or even more. You should also purchase hole saw spindles, which will help keep the saw stable while you work.
To safely cut wood, use hole saws in a power drill at low speed. To make smooth holes, cut halfway through the wood, turn the wood and cut counterclockwise until you have a clean hole. There are also combination hole saws with various round saw blades in different sizes.
Wood
The flat drill bit is a common form of wood drill bit. This bit features a raised point in the center and two raised points on each side. These help keep the bit straight while drilling. This bit can quickly and easily cut clean holes in wood when used in a power drill. Except wood and plastic, they should not be used.
A point drill bit is a good option for small holes. The centering tip of this twisted drill bit ensures beautiful holes. You can’t go wrong with a Forstner drill bit for flat bottom holes. Brace Auger Bits are roll forged bits ideal for drilling extremely deep holes. For precision drilling, they have a threaded centering tip. Four-flute turbo wood bits are also useful for a variety of woodworking jobs.
Roof tile
Drilling tiles requires the use of tungsten carbide or diamond tipped tools. The typical glass and tile drill bit is flat with a pointed edge that can drill through tile and cleanly pass through ceramic and glass without fracturing the material.
When using these types of drill bits, you should always use lubricant. Water is a good option. This is used to keep the tip cool. As you work, take periodic breaks to lubricate the tip. It is best to use a glass and tile drill bit designed especially for this material.
Up your DIY game with drill bits
Whatever type of drill bit you choose, maintenance is essential. Always keep them in cases or boxes, preferably in the ones they arrived in, so they don’t fall out and end up in your toolbox. Clean them too. The bits should last a long time if you use the right bit for the job. Do not force them into the materials and keep them safe.
