Most people who do DIY understand the significance of utilizing the proper tool for the job. While people may spend hours studying which drill to buy, they frequently overlook what will come into touch with their work material: the drill bit.
Choosing the appropriate drill bit is about conserving your most valuable resource: time. So, for maximum efficiency, learn about the many types of drill bits and know which is best for you.
Understanding Drill Bits
Drill bits are vital for many DIY projects around the home and on the job site and are used by a wide spectrum of experts and DIYers. They are used by electricians, carpenters, and plumbers to cut holes for wiring, pipe, and joinery.
Home DIYers use drills to connect large items like flat-screen TVs or bookcases. However, if you have the correct drill and drill bit, you may drill through the center of the brick wall to run the wire outside. Make sure you plug the hole when the wire run is finished.
Luckily, it is easy to buy drill bits in Australia. With the use of the Internet, you can access reputable stores online. This allows you to browse their seemingly endless catalogs in the comfort of your home. So, if you can’t leave your home to go to a hardware store, you can just have your drill bits delivered to your door! Easy, right?
Types of Drill Bits
Is having specialized drill bits necessary when multi-purpose bits will suffice for most projects? The solution is dependent on two major criteria. First, consider what type of project you’re going to work on. Second, consider the drilling material. A multi-purpose bit will suffice 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 need to choose bits specifically designed for the material you’re working with. Using the incorrect bit is never good. To know more about drill bit types, read more.
Masonry Bits
Masonry bits are used for a range of tasks. They have adequate power to drill through brick, concrete, stone, and thick tiles. Their 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, poor quality, cheap parts can shatter. Always use high-quality bits and avoid excessive pressure or speed when drilling.
For harder materials, a slower rotating speed is preferable. This will prevent the tip from becoming too hot. To avoid dust buildup, you should remove the bit frequently. Several sizes and lengths are available. Do not drill deeper than the bit’s flutes; it will seize in the hole. Long pieces are great for use on walls.
SDS
When drilling into masonry, SDS bits are, without a doubt, the gold standard. These pieces are primarily utilized in concrete. They are fluted and have a tungsten carbide tip. SDS are designed for use in rotary hammer tools. Several kinds range from standard to industrial. Standard bits can penetrate clay brick, fire brick, and concrete, whereas industrial bits can penetrate lintel and hard masonry.
Twist
Most people envision a twist bit when they think about drill bits. These are quite ubiquitous and should be in the toolbox of any home DIY enthusiast. Many contain multi-purpose bits for use on wood, stone, and plastics. Others are designed for use with concrete and metals.
The tip aids in cutting through the material, while the twisted design aids in debris removal as the drill goes through the material. These parts are available in various sizes, from extremely small to extra large. Carbon steel is used for standard wood bits, whereas High-Speed Steel (HSS) is utilized for metal, masonry, and other strong materials. If you’re drilling into metal, use an HSS bit.
Hole Saw
Hole saws are round in shape and feature 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 48mm or even deeper. You should also buy a hole saw arbors, which will assist you to keep the saw steady while you work.
To securely saw through your wood, utilize hole saws in a power drill at a low speed. For smooth holes, saw through until halfway through the wood, and turn the wood and saw the opposite way until you have a clean hole. There are also combination hole saws with various round saw blades in varying sizes.
Wood
The flat bit is a common form of wood bit. This bit features a raised point in the center and two raised points on each side. These aid in keeping the drill bit straight while you drill. This bit can rapidly and simply cut clean holes into wood when used in a power drill. Apart from wood and plastic, these should not be used.
A brad point bit is a good choice for tiny holes. The centering tip on this twisted bit ensures nice holes. You can’t go wrong with a Forstner bit for flat-bottomed holes. Brace auger bits are roll-forged bits ideal for drilling extremely deep holes. For precision drilling, they have a thread centering tip. Four-fluted turbo wood bits are also useful for a variety of woodworking jobs.
Tile
Drilling into tiles necessitates the use of tungsten carbide or diamond-tipped tools. The typical glass and tile bit is flat with a pointed edge that can drill into the tile and cleanly break through ceramic and glass without fracturing the material.
When using this sort of bit, 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 bit designed particularly for this material.
Step-up Your DIY Game with Drill Bits
Whatever type of bit you choose, maintaining your bits is critical. Always store them in cases or boxes, preferably the ones they arrived in, so they don’t slip out and end up in your toolbox. Clean them as well. Drill bits should last long if you use the proper bit for the job. Don’t forcefully drive them into materials, and keep them safe.
