Drill bits are usually attached to a drill, which cuts holes in the workpiece by rotating the drill bit. The drill will grab the shank, which is the bit’s upper end, in the chuck.

They can pierce a variety of materials. Wood, metal, plastic, ceramic tile, porcelain, and concrete are just a few of the materials available. Drill bits are available for a variety of materials, including steel, fiberglass, cast iron, aluminum, brick, sheet metal, vinyl flooring, copper, and others.

Drill bit sizes that are common are available. A drill bit and tap size chart list drill sizes in both metric and imperial units, as well as the required screw tap sizes. Non-circular cross-section holes can also be made with certain specialized drill bits.

Types of Drill Bits

  • Twist Drill Bit: This is the most commonly utilized drill bit, and it can be used to drill holes in a wide range of materials such as wood, metal, plastic, and others. They are not, however, suitable for use in masonry. Since twist drill bits are self-centering, they don’t need pilot holes in most cases. These general-purpose bits are a great option if you don’t have a specialized project in mind.
  • Step Drill Bit: This drill bit is conical in shape with a stairstep pattern. You can drill holes of varying diameters in wood, metal, and plastic with a single drill bit. This is the drill bit to use when drilling sheet metal.
  • Insert Drill Bit: They are mainly encountered on machine tools and are used for drilling large diameter holes. Since the inserts can be replaced when they become worn, they are more cost-effective. They also have multiple cutting surfaces per insert, making quick replacement possible.
  • Reamer Drill Bit: Precision reamers are being used to enlarge a previously formed hole by a small amount while maintaining good precision and leaving smooth sides. Non-precision reamers can also be used to enlarge holes or remove burrs.
  • Center Drill Bit: The blade on the center drill bit is razor-sharp and made of HSS high-speed steel. It has low energy consumption and a long lifespan, as well as effects and wears resistance.  In soft metal, mild steel, aluminum, acrylic plastic, and wood, it’s used to make drill bit starting holes.
  • Conical Drill Bit: They are used to drill a precisely shaped pilot hole for screws and as a pre-driller for nails, which reduces the risk of the workpiece splitting. Drill into the head end of tool handles to easily create a properly sized hole for widely used conical shaft wedges.

Application of Drill Bits

Drill bits are used in a wide range of applications, including woodworking, metalworking, and construction, and machine tool fabrication, glasswork, reaming, boring, counter-boring, tapping, and utility. Personalized versions are needed for medical, space, and micro applications.

Are Drill Bits Universal?

They can be applied to any situation. That should do the trick. Drills have three-jaw chucks that clamp down on whatever you put in them, allowing them to use both round and hex bits.

Whether you want to hang a picture, install shelving, or build new cabinets, you’ll need to drill a hole at some point. Having a drill bit that can be used for a variety of tasks around the house will make these projects go quickly, easily, successfully, and possibly even enjoyably.

Due to the growing demand for quality tools for non-professional workers, companies have introduced universal tools that can be used for a variety of tasks. Universal drill bits that can be found in home improvement and hardware stores could be used to drill holes in a variety of materials including wood and concrete. Some, on the other hand, may not be suitable for drilling into more delicate materials like ceramics and glass.

You don’t need to own a separate drill bit for each type of material you plan to drill into if you have universal drill bits (unless you are drilling into glass or ceramics). Universal drill bits are not cheap, so they should be properly stored and maintained.

Keep all drill bits in a box. Allowing them to roll around could cause them to become blunt, affecting the quality of your work. Also, use appropriate sharpening tools to sharpen the drill bits before they become blunt.


They’re used to drill holes in a wide range of materials. They come in a variety of drill bit sizes. Examine the above outlines to determine whether drill bits are universal or not.

Does it make a difference which drills bit you use?

For softwoods, use a bit that would be 1/64″ relatively small than the intended hole size. When operating with other materials, use the same-size bit as the hole. If in doubt, use a drill bit that is 1/64″ larger than the hole you want to make. Variables like wood density and screw-type will be taken into account.

Are the screws used by drill bits the same size?

Without taking threads into account, the drill bit should be the same size as the screw shaft. Simply align a screw with the drill bit side by side to achieve this. You’re good to go if they’re both the same size. Most bits and screws will have measurements written on them.

How does one recognize a hammer drill bit?

Masonry bits appear to be wood bits at the first glance since they have a deep spiral groove that aids in the removal of debris from the hole as you drill. The primary visual distinction between masonry bits and standard general-purpose bits is that masonry bits lack the blunt, tenderly rounded tip found on standard general-purpose bits.
