Best Concrete Drill Bits of 2018: Your Complete Guide

Concrete, among other materials, is the hardest to drill. It’s not enough to that you got the top performing drill, you also have to invest in trusty bits that will last long. Cheap ones are good for starters but the result could be messy drilling and bigger expenses to replace the dud pieces. This shouldn’t be the case if you’re working on a masonry project. What you need is the best concrete drill bit to accompany your heavy-duty equipment.

From years of experience and countless broken bits from my past projects, I now learned the biggest lesson when it comes to buying drilling equipment: it’s the quality that counts.

Here, I’ll help you out to choose the right drill bit for your concrete. I also included some commercial options that you can purchase right away. But before the buying phase here’s what you should know first.

Should I invest in a set?

This one depends on the concrete job that you’re working on. If you’re dealing with different types of concrete surfaces, a set is a wise purchase. This will also come handy whenever you’ll need to do some emergency drilling at home or at work. Again, this is a matter of preference. Drill bit sets aren’t too expensive as you can get one for as low as $15 or $20.

DEWALT has three and seven-bit sets that you can buy for $8 or $15 respectively. The DEWALT DWA5103 is an affordable choice for a set of three without sacrificing reliability of drilling. This will last longer and you don’t have to break the bank just to get a new set.

If you have more to shell out, I would recommend my trusty DEWALT DW5207 Set of 7 Drill Bits. These are good for concrete and it will give a wide variety of tips. You can use all of these in almost every type of masonry work. For about $15, this is best concrete drill bit you got here, my friend.

What should I consider before buying drill bits?

You should check first what you’re drilling. If you’re installing wall plugs, a 1/4” or would be the universal pick. A 5/16” would also work well for the same task. This is if you’re just doing simple home jobs. For a more specific approach, I list down options and guides based on types that you can use on concrete drilling.

CONCRETE BITS

Multi-Purpose Bits

If you want to have a drill bit that you can use for almost every drilling job, you can check out a multi-purpose but. Most of the time, this has a special tungsten carbide tip with the ground diamond that can drill through every material: plastic, concrete, metal, ceramic, etc. This is best used for rotary drilling from time to time. If you need to drill holes in concrete regularly, you would have to use a dedicated bit for best results. Anyway, here’s what I can recommend for a choice of a multi-purpose bit.

If you don’t have the budget to avail Bosch or DEWALT bits, you can check out the ARTU-USA 01010 Drill Bit. This comes in different length and sizes that are made with tungsten carbide tips you can resharpen. This best concrete drill bit can withstand 2000F of drilling with no center punch needed. You can use this one your cordless or corded drills but keep in mind that this bit will work best except for mild steel like copper, aluminum, galvanized pipe, etc.

Diamond Bits

Tough concrete might need more than the usual multi-purpose bits as these are way harder. In this case, you can use a diamond bit on your drill. But unlike the multi-purpose one, this should be supplied with water frequently to avoid overheating. This is better than diamond core drills as this has a solid construction and will last longer in use. The fact that diamond is tough means you can drill anything using it, but as a word of caution, avoid using it on soft materials like plastic and thin metal. You should also use this in a low RPM setting for seamless drilling.

For this one, I’m confident to recommend the DEWALT DW5572 1/4” Diamond Bit. It has a sturdy diamond tip and a spiral thread for efficient and continuous cooling once you supply it with water. You can use this on your tough masonry work like concrete, granite, and even porcelain. This is a cheap find for less than $20 and I assure you that it’s not lightweight in drilling holes.

I must admit that diamond bits are a bit pricey. If you want a more economical choice, the eBoot Diamond Drill Bit will also be a good choice. It’s not as sturdy as the DEWALT one in my opinion but it’s a wise investment for a set of five. This best concrete drill bit comes in 3/8, 1/2, 3/4, 5/8, one inch, five cm, as well as 5.5 cm in diameter. Just add a lubricant while using this to avoid sparking and to lengthen its life.

SDS Bits

The Special Direct System or originally ‘Steck, Dreh Sitzt’ is developed by the Bosch company during the ‘70s. This is commonly used for rotary hammer drills to drill holes on dense masonry materials like limestone, granite, and concrete. Types of SDS bits depends on the drill you have but the most common are the SDS-Max and SDS-Plus. Usually, SDS-Plus would work for concrete, but if you’re skeptical of quality, you can invest on SDS-MAX. The latter will be the best if you have other masonry materials to drill on a massive scale.

I can recommend the one from the original, which is the Bosch HC5033 Wild-Bore SDS-Max Carbide Tip. This has a specification of 3/4” x 31” x 36” and can work high-speed for the toughest concrete surfaces. Just keep in mind that this one is for massive drilling and not the wall-plug type of task. If you’re into that kind of drilling work, you can check the second recommendation after this.

To continue, the Bosch SDS-Max has a solid carbide end to ensure wear and tear while in use. So far, this best concrete drill bit is performing well on my end.

As promised, the Dewalt DW5403 Rock Carbide SDS-Plus bit is the second choice. If you’re drilling three-inch deep holes on concrete, nothing can match the performance of this one. This has the dimension of 3/16” x 4.5” x 6.5” that’s easy to use. The four-flute helix design of this bit makes material removal faster and without the tendency of breakage. You can even drill on 5,000 psi with this bit and it will still function like new. It’s also ten times cheaper than the massive SDS-Max from Bosch.

Hammer Bits

If you have a hammer drill on your toolkit, you’re in good hands when it comes to drilling holes in concrete faster than normal drills.  This is best for light masonry like concrete blocks or poured concrete. It’s easy to find a bit of this drill as it’s a common thing, but the crucial point is finding one that will last long. Expensive ones are usually sturdier as the carbide tips are superior to cheap pieces. Like what I said earlier, you should shell out a little more if you want the best concrete drill bit.

Since the pounding power of hammer drills vary per model, it’s safe to invest on the toughest bit available. What I can suggest is the DEWALT DW5469 that’s 1-1/8” with a massive 16” usable length. It boasts a rock carbide tip that will last long on concrete drilling and a flute helix design that makes material removal easy. You can drill 10 inches of a concrete hole using this bit, as smooth as butter. It has stronger steel for less risk of breaking. This one could be expensive at more or less $35, but trust me, DEWALT never disappoints.

Again, if you don’t have the budget for the best concrete drill bit, I’ll suggest the Bosch LBH0035 3/16 hammer bits. It has a diamond-ground component at the tips aside from the carbide material. This is a reasonable bit for moderate drilling needs for concrete.

This Bosch set of five has a deep-cut spiral design, but if you’re going to ask me, I prefer the flute helix of Dewalt. Anyway, you’ll get what you pay for as per the price. Great bits if you’re into buying sets.

The Takeaway

The best concrete drill bit I listed here are just some of the ones I tried among the dozens of bits I had in the past. All are functional but as what I like to emphasize, spending more will get you more perks in the drilling department. I’m quite a fan of DEWALT but I won’t discount the efficiency of other brands despite their price.

Check out, try any of my suggested concrete bits here, and see which works for you. Let me know once you’ve got results!
