Many times, people encounter activities that require drilling of a hole. To carry out such activities, they must apply the right type of a drill bit. It is a world of tiny, yet important accessories for daily living. More information about drill bits is available at Drill Bit Best.
However, this piece seeks to advise users on the correct practices of using drill bits. It sheds light on how to sharpen them and on how to use the bit appropriately.
At standard level, an average handyman simply needs a set of masonry bits and a high-speed drill. However, for advanced tasks, there may a need for larger bits or specially designed models to accomplish a given task. High-quality drill bits are expensive and therefore demand good care to make them last longer. They should be kept safe is a special case or drawer where they are not exposed to corrosion, dust, or dirt, which can damage their cutting edges.
Besides, users should learn how to sharpen drill bits appropriately and in good time, instead of waiting until they become blunt. A sharp bit works faster and enables the user to apply less effort. Besides, it also produces a cleaner hole.
Also known as twist drills, they are probably the most common type of drill bits. They are applicable in both electric and manual drills. They cut materials using their sharp front edge while the spirals remove debris from the hole. The spirals also help keep the bit straight during work. Twist bits can be used when drilling timber, plastics, metal, or similar materials. These bits are available in two main styles:
- The high-speed steel bit: They can work on almost any material. Twist bits can stand very high temperatures during work.
- The carbon steel drill bit: This type of drill bit is most suitable for wood drilling and not metals. They are more brittle and less flexible compared to the high-speed bit.
Besides, twist bits can have a special coating with Titanium nitride. In such cases, the bit looks golden. The coating serves two functions: It adds strength to the bit and it provides a self-lubricating quality. This is mostly necessary when working on metals and not other materials.
Availability of twist bits
Twist bits come in various sizes ranging from 0.8 millimeters to 12 millimeters and more. They are meant to drill smaller holes. Users should take special care when using the bits with the smallest sizes because they are more brittle and thinner. They require just light pressure during the drilling process.
When it comes to sharpening the bits, experts recommend using a grindstone, oilstone, or a special drill sharpener.
