Consider before buying the Best Drill Bits for Electricians

Well, whenever you decide to buy any drill bits as an electrician, make sure you take a look at the following guidelines since every professional follows the same rules. We have some good information that you should follow before buying our recommended tools.

Material Type

You can choose between low-carbon steel bits and high-carbon steel bits. We always prefer cobalt steel mix drill bits, which are constructed from a 5%–8% cobalt alloy. Cobalt has a melting point of 1495 °C, and its boiling point is 2927 °C for high-temperature applications. Because of the cobalt, the tool is ideal for sharpening rather than replacing.

Cobalt drill bits, in particular, are perfect for metal since they have a high resistance to enormous heat and are suitable for hard materials such as stainless steel, titanium, or cast iron. Though they are more expensive, cobalt drill bits are superior to titanium drill bits and will last much longer.


The performance of the drill bit is also important, and for drilling a high-speed surface, you will need high-speed, metal, or twist bits. These are ideal for drilling little holes or sections.

Proper Size

Knowing the best size for your project is critical. Most high-quality brands feature size and names in their own unique way, whether through letters, metric measurements, or numerical letters of the alphabet. For instance, typically electricians drill for ¾” holes, which are perfect since you can simply remove the cable and modify up to three cords.

Coating in Black Oxide

Black oxide is a corrosion-resistant coating applied to steel drill bits to reduce friction between the bit and the workpiece. Black oxide bits have a 50% longer life than normal HSS bits, as well as greater speed and durability.

Coated drill bits of this sort are ideal for drilling steel, aluminum, copper, wood, plastic pipes, nylon, and other composite materials. However, only cut through metals that are less than 1/8 inch thick.

Coating with Titanium

As an alternative to black oxide, get the titanium nitride-coated drill bits since they are corrosion-resistant and reduce friction. Another benefit is that you are getting increased surface flexibility and a thermal barrier to decrease temperature development. A titanium nitride-coated drill can be great for drilling in wood or metal.

HSS or High Strength Steel

Looking to drill wood, fiberglass, PVC, or other soft materials? High-speed steel, or HSS, drill bits are the finest alternatives. HSS bits are made of carbon steel with the addition of other components such as chrome and vanadium, resulting in an excellent performance.

Carbide Drill Bits

Solid carbide drill bits with a hardness of 75 HRC are an excellent choice. When compared to HSS and titanium bits, this drill bit keeps its sharpness for a longer period of time. This type of bit is typically used for drilling tile or masonry.

What kind of Drill Bits do Electricians use?

We have a variety of drill bits to accomplish the electrical work. Commonly, auger bits and spade bits are used while drilling into studs. If you don’t like any of them, you can look into the alternatives listed below.

What kind of Drill Bits do Electricians use

Auger Bits

Auger drill bits are the first and most used bits for drilling deeper holes. The complete fluted style is the most popular, but be sure your drill is powerful enough to handle the bit. Auger bits are the best option for drilling deep holes larger than 3/4 inch in diameter. With a threaded tip, this auger bit pulls the bit forward and guarantees smooth, accurate drilling.

Spade Bits

We like good drill bits, but if the price is right, no one wants to pass up the opportunity to get a bit like a spade bit or a paddle bit. The spade drill bit, due to its form, sends chips out rather than sending them up. You can use this to finish any woodworking project.

Twist Bits

Aside from auger and spade bits, twist bits are another popular option for cutting anything from wood to plastic steel to concrete. This sort of drill bit allows it to glide more smoothly through your material and create a path for shavings to escape as you drill. When drilling a hole with a diameter of 1/2 inch or less, use a twist bit.

Step Bits

When you don’t have a twist, auger, or spade bit, you can use step bits instead. This drill bit is especially useful when drilling a hole in thin metal, such as breaker boxes or sheet metal. It has a flat flute with a bit of shrink at each stage that allows drilling in sheet material and other thin metals. This drill bit has a flaw in that it cannot drill a hole with a diameter of 1/8 inch.

Installer Drill Bit

Installer drill bit? Have you heard anything about this before? A unique twist bit designed for installing security system cabling. Electricians can do the drilling through the ground, wall, or other surfaces, which requires inserting the wire into the tiny hole and drawing it back through the hole. Remember, any hard surface up to 1 by 8 inches.

Countersink Drill Bit

Some people have inquired as to what a countersink drill bit is as they never introduced themselves to this type. It’s a screw pilot bit that’s great for drilling wood, as well as another drill bit that electricians will appreciate. Given this, it is possible to drill pilot holes, countersink holes, counterbore, and countersink a clasp, and secure a plug over the fastening head.


What size hole do you drill for electrical wire?

Professional electricians may prefer to drill 3/4-inch holes dead center on a 3-1/2-inch broad stud. However, choose the one that is perfect for your needs and capable of drilling any material.

What kind of drill bits do electricians use?

When looking at the electrician’s drill bit set, we frequently identified they utilize the auger and spade bits for drilling out. However, twist, step, installer, and countersink bits are some other options. They all serve different purposes as drill bit tools. So, choose among them what is sufficient for your electrical project.

What happens if I drill into an electric wire?

Nothing occurs unless there is power and the drill is connected. Drilling into an electric wire, on the other hand, will damage the cable and cause the lights to turn off or blow the fuse.

Can I drilling into a stud with electrical?

Studs should be hit in places where electrical cables should not be hit. Also, the wires will not pass between the drywall and the stud.
