  Aug 15, 2022 6:51 PM

There are several factors to consider when purchasing a concrete drill bit, and getting the appropriate one is critical. To drill through stone, granite, marble, or granite, you'll need a powerful drill made of a hard metal like tungsten carbide. In addition to being specifically built for stone, masonry drill bits can also effortlessly bore through these difficult materials.

Carbine tungsten is the principal component in each of the drill bits listed below. These bits are capable of drilling through hard rocks. When using masonry drill bits, the wide flutes allow them to remove a lot of material from the bit as they are drilling, keeping it from being jammed.

Due to the frequency with which we are forced to drill into metal and stone, we conducted extensive study to determine the best drill bits for drilling concrete. In order to find the best drill bits for 2022, we consulted with our lab staff and analyzed and assessed all of the major drill bit brands.

Buying Guide

SDS Bits

SDS bits are a fantastic option if you're seeking for exceptionally powerful bits that work well with concrete and other tough materials. Reinforced concrete can't stand up to these pieces. SDS-Max and SDS-Plus bits are among the options we provide. In terms of size, the SDS-Max bits are the largest and thickest, while the SDS-Plus bits are narrower. The only way to use these bits is in SDS drills with an SDS chuck designed for hammer drills.

Tungsten Carbide Tips

Drilling into concrete is difficult, and tools frequently overheat during the process. Carbazed tip drill bits for concrete and stone are available. It is created by mixing carbon and tungsten, which results in a dense and durable metal. Because of its high melting point, carbide-tipped tools can resist extremely high temperatures. To avoid overheating and the harm it can inflict while drilling, this prevents it. If you want the best results without harming your bits, always use carbide-tipped bits.

Profiled Tip

Masonry bits and twist bits have extremely similar tips. The shaft and shank of both are the same. As the drill hammers into the concrete, the fluted tip helps to clear the dust. The drilling process is aided by the unusual form of this tip. Bits with a hammer drill can easily break into tough masonry like concrete. For rapid drilling, turbo concrete bits have rotary hammer grade centring tips. Heavy drilling is possible thanks to the profiled tips on industrial concrete bits.

Materials

Black Oxide (Coating)

The steel drill bit has a black oxide coating applied to it to increase corrosion resistance and decrease friction with the workpiece. It's a low-cost general-purpose design that works well with a variety of materials, including wood, softer metals, plastics, and composites. The negatives are that they don't last as long as some of the other twist bit options, and the coating fades off the cutting edges, making them less effective.

You throw away the worn-out pieces. Also, don't expect to be able to cut through metals thicker than 1/8-inch.

Titanium (Coating)

Titanium nitride is a substitute for black oxide in terms of corrosion and friction resistance. Additionally, a thermal barrier lowers heat buildup by increasing the surface hardness. The end product is a drill bit that lasts longer than black oxide would have..

Compared to black oxide, titanium drill bits tend to drill faster and the chips travel more easily between the flutes. As the titanium nitride coating fades off the cutting edges, you lose some of the benefits of the coating. You'll also have to shell out more money to get these.

For metal and wood drilling, titanium is a good option. If you're working with plastics or composites, you're better off using your low-cost black oxide bits rather than purchasing specialty bits.

Cobalt (Steel Blend)

Bits with a cobalt content of 5–8 percent are known as "cobalt-coated." This is because the cobalt is included into the steel blend rather than being a separate coating. As a result, sharpening them instead of replacing them is a great idea. Sharpening will save you money because black oxide and titanium are substantially more expensive than sharpening.

 

Cobalt bits can drill through almost anything, but because they are so expensive, most professionals only use them for metal drilling. If you don't want to risk dulling your only bit capable of drilling through cast iron by using it for everyday activities, this is an excellent idea.

Coatings

Your drill bits' performance will be affected by the sort of coating they have. Black oxide, titanium nitride, diamond powder coating, and titanium aluminum nitride are all examples of coatings. Depending on the sort of coating, you'll be able to withstand more abrasive elements for longer.

Sharpening Techniques

Drill bits will eventually need to be sharpened if you want them to perform as well as they did previously. That's why we're taking a close look at the drill bit sharpening options.

Fortunately, maintaining the sharpness of most of them is as simple as using basic sharpening techniques. Before purchasing a drill bit set, be sure to check for any maintenance requirements.

Brand

Because not all brands provide the greatest drill bits, choosing the right one is critical. All of the brands listed above are among the greatest in their respective fields.

Drilling with Bosch or DeWalt bits is a surefire approach to get the best bits. It's worth your time to check out the drill bits from other well-known companies to determine if they meet your standards.


FAQS

Can I Use A Regular Drill Bit For Concrete? 

But it will quickly exhaust your drill bit supply and be sluggish in its digging capabilities. On the other hand, it's not a good idea to use it without a drill bit. Drilling masonry relies on slicing rather than cutting the little pieces rather than using a saw or chisel.

For the most part, you'll want something with a number of sharp and rough edges (not sharp). He invented the tri-cone drill bits, a tool for impact rather than cutting impervious rocks at high speeds. This means that hammer drills would be necessary, as well as brick-bits.

A masonry bit and a hammer drill are essential for the process, making it easier and safer, as well as delivering superior results.

What Does A Masonry Drill Bit Look Like?

It is easier to use Masonry bits than larger twist drills because of their more compact spiral design. Their large arrow-shaped heads make them easier to recognize. When cutting through masonry, hammer drills are the tool of choice for shattering it to pieces.

Hard stone substrates, such as bricks or breeze blocks can be used with these paints. Using them on wood will take longer than using a wood drill that is appropriate for the job.

Is it good to drill concrete at a slower speed?

Yes, slowing down the speed of the drill bit while drilling into concrete is recommended to avoid overheating the drill bit. In most cases, you should begin slowly and work your way up to more pressure. Drilling concrete at 350 to 750 rpm is the ideal speed.

Are concrete and masonry drill bits the same?

It's not. The only difference between concrete and masonry drills is the drilling heads. The cutting head of a concrete drill is composed of Widia plate, but the cutting head of a masonry drill is hardened metal.


Conclusion

With the best drill bits for concrete listed in the guide above, drilling through concrete has never been easier. Now that you know what drill bit to use for each project, you'll find it much easier to get things done.

To get a better idea of what other people think of a drill bit set, we suggest reading reviews online. It's wise to get a set just if you're confident that it's the best value for your money.
