Drilling a hole is necessary in many situations, including putting up a shelf, constructing a cabinet, or attaching a lighting fixture. And, to get the job done properly, you’re going to need a sharp and sturdy drill bit. This guide will take you through the main types of drill bits.
Twist bits, often known as twist drills, are a type of drilling equipment that is quite popular among handymen who use either a hand or electric drill. The front edges slice through the material, while the spirals along the length assist in maintaining the bit straight.
Screwdriver bit drills
Similar to SDS Drill Bits, these bits are designed to fit in a rechargeable screwdriver and have a hexagonal shank. They’re fine for drilling pilot holes, but because these screwdrivers have little power and small bit sizes are hard to come by, they’re limited.
Tile bits may be used with a hand drill, but are best suited to a low speed setting in a variable speed power drill. To keep the tip cool while drilling glass, use some sort of lubricant.
Flat wood bit
The tool’s intended use is with a power drill only, and it includes a center point that locates the bit and flat steel on either side that cuts through wood. Drilling holes in solid wood can be difficult, as the hole does not have to be perfectly round. If you don’t use them often and/or need a few bits at once, they’ll save space and money by staying together instead of having separate ones for each project.
Drills with these blades are intended for breaking through brick, block, stone, quarry tiles, and concrete. The cutting tip is frequently composed of tungsten carbide bonded to a spiralled steel shaft.
Masonry drills may be utilized in a hand brace, although they’re typically utilized in a power drill. The majority of masonry bits can be used with a hammer action power drill, however always double-check since the action is quite harsh on the bit and less expensive bits have been known to shatter. To avoid overheating the tip, never use a high speed for drilling into difficult materials, and empty the bit to clean it.
Wood Auger bit
This is a great option for drilling huge, deep holes in wood or thick manufactured materials. A hand brace should generally only be used with an Auger bit. The bit will cut a clean and deep, flat bottomed hole that is smooth and level.
The bit’s cutting edge is chisel-like and removes waste within the previously cut circle, while the single spur sharpens and defines the hole’s border. The threaded centre engages with the wood and draws in the bit. Because of this ‘pulling’ action, the bit is definitely unusable for use in a power drill.
