It is interesting to note that there are different sizes of drills. The bigger the product, the more power there is in drilling or demolishing concrete.
The right way to use this accessory is to start with low numbers in millimeters. For example, you use a smaller bit and if the concrete doesn’t stick, you can increase the bit and try again until you get it.
For this reason it is important to have not just one, but several drills, different in size. The best drills for concretes have a very elaborate work on the tips. This is important as the product does not get stuck in the hole during drilling.

Concrete drill or wood drill?
The concrete bit is harder and thicker than the wood bit. This is necessary for the product to withstand the pressure of hammers or drills.

Cutting the concrete drill has more impact and has a less sharp composition than wood drill bits.
Which drill size to use for each service?
Drills have sizes measured in millimeters that generally range from 4mm to 10mm.

Purchasing criteria: Factors to compare the best drills for concrete
Okay, you just found a model that looks perfect and is dying to buy. Very calm at this time! First, review the offer against the purchase criteria listed below:
To make it easier, we will explain each of these purchasing criteria. Read calmly so you can become an expert when it comes to knowing if an offer is worth it or not.
It is very difficult to find stores that sell only one drill unit. As these products are cheap, shopkeepers prefer to sell in kits that can range from 8 to 100 or more drills for concrete.
If you need to use the drill bit for concrete in different forms of work, buy kits that have different sizes. Those who perform the same type of service several times benefit from kits that have units of identical sizes.
Although this is not a rule without exception, those who need the drill bit for concrete also need other bits for other services in wood or metals.
Buying the concrete bit at a store and purchasing other bits at other stores can be expensive and laborious. Therefore, it is worth buying the cases that come with different types and sizes of drills.
This tip is also important for the sake of prudence. After all, when buying the case from a trusted brand there is more security in daily work.
In general the product warranty is 90 days. If the brand or store offers more guaranteed time, it is a sign that there is a certain confidence in the quality of production.
Generally, if the drill has a longer warranty period, it is worth trusting the purchase of the product.
However, policies usually only cover factory problems and not for misuse of the product. If you take the concrete drill out of the packaging, use it and break it, that’s it. The brand hardly allows to change even if the model is within the warranty period.
Exchanges or refunds happen more when the product is already in trouble before being placed in the drill.
The concrete drill is more suitable for professional use. Whoever works with this product every day knows the ideal drill size for each different use.
Be calm if you are not a professional. In these cases, always try to use smaller drills and only increase the millimeter if you notice that it is difficult to drill the concrete.
As you have seen in reading this far, different concrete jobs require a specific type of product size.
When buying the concrete drill from physical stores or online you should consider the tip diameters.
This criterion is very important because the concrete drill body is thinner than the tip. The model has this format so that the powder can flow better during the work.
A common mistake for first time buyers is to buy the wood drill bit thinking it is a concrete bit.
This often happens when shopping for physical stores, because online store descriptions tell what the product is for.
To avoid problems a good tip is also to keep an eye on the total composition of the product.
The concrete drill has a thicker body and alloys with superior hardness when compared to wood drill bits.
There are many immoral sellers who apply the old drill blow. It works like this: the store announces that the drill is for concrete when in fact it is only useful in light woods.
These offending shopkeepers do this to take advantage of it because a large part of the public is not an expert. Then you’ve seen it, right? When you use the product on the concrete in a few seconds the drill breaks!
There is a way to avoid this shopping error by analyzing the tip. Without exception, drills that serve to drill concrete have a head (tip) that has an arrow shape.
