Best Concrete Drill Bit Reviews 2017

best concrete drill bit

If you have read my article on how to drill into concrete, then you will know that you need a good quality masonry bit to do the job. The size of the bit that you need, will of course depend on the size of the hole that you need to make. One thing is sure, trying to drill through any type of brick, mortar or concrete without using a masonry bit will be impossible.

You will probably also notice that throughout my website, I advise strongly against using cheap drill bits for any job. My reasons for this is that they just will not do the job properly, and even if you somehow manage to drill one hole, then the cheap drill bit will be blunt and pretty useless after that.

It is honestly so much better to buy a decent quality and have them for a long time. When I was starting out I used to buy the cheapest because that was all that I could afford. The net result was that I ended up spending more as I constantly had to replace them.

A Single Masonry Drill Bit or A Set of Bits?

This completely depends on how much drilling you will be doing into concrete. If it is just for a couple of straightforward jobs, then you can get away with just buying maybe a couple of single sizes. Typically these will be a 14″ and a 5/16″ as these would be the most commonly used. These two sizes will cater for wall plugs and various anchor type fixings. These can also just be the standard length as wall plugs and anchors are not that long.

You do of course always make the hole size smaller than the concrete screw that you are using. For example a 3/16″ screw would need a 5/32″ hole drilled, and a 1/4″ screw would need a 3/16″ hole drilled. With wedge anchors or sleeve anchors you would drill the same size of hole as the size of the anchor.

If you are going to be doing a lot of work around the home, then I would recommend buying a set of masonry drill bits, which gives you more flexibility in hole size, and what attachments you can use. You can pick up a really good set of masonry drill bits for less than $20, and believe me, that is a really good investment.

The only other consideration is length of the drill bit. The main use for longer masonry drill bits, especially with concrete, is drilling through holes to push a cable through, or things like, drainage pipes for washing machines. The normal standard size will not be long enough to do that. I have heard people say you can drill one side and then the other and match them up. Yes you can if you are feeling lucky, and I have never seen this accomplished in my many years of working in the trade. If you have the proper length drill bit, then it is a breeze.

I have shown here the set of masonry drill bits that I use for drilling through concrete. It is a simple 7-piece set and they work fast. They have a strong carbide tip, and are designed for drilling into concrete, block, brick and other types of masonry. These are the DEWALT brand and for me they are flat out the best bits that I have used.

Over the years I have been able to use any number of different brands but I keep going back to these as they are the best.

Extra Long Concrete Drill Bits

In terms of the longer drill bits, I would avoid buying a set of these. They are not something you will use a great deal, and perhaps only ever for one or two jobs. I would not be spending money on buying full sets of these as most of them would not get used. Just buy these individually as and when you need them is my advice. These longer drill bits are expensive and on average about $15-20 each. DEWALT and Irwin are the best brands for these. You will also need a pretty powerful drill to use these and get through deep walls.
