Drill bits are essential tools used in a variety of applications, from woodworking to metal fabrication. They come in a variety of sizes and styles, so it's important to know what type of drill bit is best for your needs. This beginner’s guide is designed to help you choose the right drill bits for your projects.
When shopping for drill bits, first consider the material you'll be drilling. Different drill bits are designed for different materials and using the wrong type of bit can cause damage to the workpiece. Woodworking drill bits are designed to cut through softwood and hardwood, while metalworking drill bits are designed for cutting steel, brass and aluminum.
Another important factor to consider is the size of the drill bit. Standard drill bit sizes range from 1/16 inch to 1/4 inch, with larger sizes available for specialized applications. To determine the best size for your project, measure the diameter of the hole you need to drill. If you're drilling a pilot hole for a screw, use a bit that's slightly smaller than the diameter of the screw.
Most drill bits are made from high-speed steel or cobalt, but there are other specialty materials such as carbide and diamond-coated bits available. High-speed steel is the most common, as it is durable and reasonably priced. Cobalt drill bits are more expensive, but they are more resistant to heat and wear, making them ideal for frequent use.
When selecting drill bits, look for those with a split-point design, which helps reduce walking and skidding. You may also want to look for bits with a 135-degree point angle, which is the standard for most materials. Other features to consider include shank type, flute type and finish.
Finally, when buying drill bits, make sure to purchase ones that are suitable for your drill. Cordless drills require drill bits with straight shanks, while corded drills require drill bits with tapered shanks.
Now that you know the basics of drill bits, you can confidently shop for the right ones for your projects. With the right drill bit, you'll be able to get the job done quickly and efficiently.
