Best Drill Bits

This set from Milwaukee consists of 23 drill bits that vary in size from 1/16 to 1/2 inches which should cover pretty much any basic task. As for the connection means, the shanks of the bits are hex, allowing using them on high-torque power tools without risking the piece loosening while you operate the drill.

Suitable for impact drills, the bits from Milwaukee can be used on various metals, wood, as well as plastic surfaces without the need of sharpening their helixes too often. Thanks to the titanium coating of the high-carbon steel they are made of, it is possible to drill holes in steel, as long as you have a suitable lubricant. Otherwise, the bits tend to get hot quite a bit.

On the bright side, however, all bits are made according to the RED HELIX design that enables quick chip removal, which should work great for both metal and wood surfaces. On top of that, the 135° split points of the bits allow for a precise start every time you begin drilling a new hole. For added convenience, the plastic container that comes together with all the bits can be used as a carry case.

Wrapping things up, this set of titanium-coated steel bits will be a great addition to the toolsets of both professional and DIY repairmen, or simply in case you need an extensive renovation to be done.

Unlike hex-only drill bit kits, this package from DEWALT comes equipped with two sets of bits that can accommodate both hex-based and round bit connections on drills.

First of all, a handy plastic carry case features 21 drill bits that vary in size from 1/16 to 11/64 (round bits) and from 3/16 to 1/2 inches (hex bits). This, combined with the titanium coating of the high-carbon steel, should suffice most basic as well as some trickier drilling tasks.

While the range of bit sizes is quite good overall, the smaller ones are prone to get hot when used for drilling harder materials for prolonged periods of time. With that in mind, it is highly recommended to utilize special lubricants if you plan on drilling metals and hardwood surfaces. As for the softer materials such as plastic, ceramic tiles, and so on, you won’t have any issues with these. To add more, the Web Taper design of the bits ensures that they will not bend or break easily, even if used in extreme conditions.

All in all, if you are looking for a drill bit set that can be used on pretty much any modern drill, this is by far one of the best options for you. These bits from DEWALT stand out with their great quality of build and heavy-duty nature of the titanium-coated steel.

Titanium nitride, or simply TiN for short, is a tough ceramic material that can be of great help when used as a coating base for steel drill bits, and that’s exactly what Makita utilizes with this heavy-duty set of drill bits.

To start off, all bits included in the package are rated for use in an impact drill and 1/4-inch hex impact drivers as well, making it an ideal option for handheld power tools. The size range, on the other hand, is not something you can call impressive by any means - only 14 pieces ranging from 1/6 all the way up to specialty bits like 5/16- and 1/2-inch impact bits. That said, even this set usually gets the job done.

Thanks to the titanium nitride coating, these bits are exceptionally durable, making them ideal for drilling holes in both ferrous and non-ferrous metals, plastics, cast iron, and even stainless steel. The only thing you should be aware of is that the smaller bits are rather thin, so it is important to keep that in mind before using them on hard surfaces to avoid bending them.

In the end, this set of drill bits from Makita is simply the best overall package for tough tasks that need addressing here and now. Hard, durable, and extremely flexible in terms of various bit sizes, this kit proves that more doesn’t always mean better.

This enormous set of drill bits from COMOWARE is designed to impress even the most demanding users out there.

Firstly, by opting for this kit, you are getting 29 bits of high-quality drilling bits. The general-purpose design of the bits doesn’t just end on that, though, thanks to the bits' HSS (high-speed steel) construction, making them the best drill bits for working on robust, durable materials. Secondly, it’s the gold oxide finish that firmly protects the metal attachments from corrosion, making certain bits good even for limited masonry use.

The only thing that we didn’t like about some bits in the package is the fact that they get dull pretty quick when used to drill harder materials, requiring you to sharpen them regularly. But other than that, there’s no actual downside of using this kit due to the sheer number of actually great bits.

Furthermore, contrary to single-flute bit kits, the double-flute construction of these bits makes them a viable choice for drilling holes in sheet steel, metals, and hardwood. Combined with the 135° split technology, the drilling process is faster and more stable (even more so, if lubricants are used).

Despite some minor drawbacks, this drill bit set from COMOWARE is definitely one of the most cost-efficient options with the best quality you can possibly find on the market today. A wide range of different bits for various tasks and drilling hard materials makes it a go-to option for specialists that use impact drills on a daily basis.

Different sizes of drill bits are generally great when you are looking for a general-purpose set. But what if you need a set of bits for a power drill? Fortunately, this M35 kit from Amoolo got you covered.

First and foremost, the kit includes 10 heavy-duty drill bits of one size - 1/4 inches. Made of cobalt steel alloy, they are genuinely good for drilling holes in a variety of different materials that include but not limited to stainless steel, wood, cast iron, aluminum, as well as other soft materials. It is important to point out that it is not recommended to use the bits on glass or ceramic materials, though, since the flute design will most probably shatter them.

Although the kit features a storage case option, the drawback of this carry case is that it is a bit inconvenient to use for rapid bit changes. So, if you need to use more than two bits at a time, we advise getting a specialized carry case for a better experience.

Case aspects aside, let’s take a closer look at the actual material the bits are made of. The M35 cobalt is a steel alloy that includes 5% of cobalt yet even these 5% are just enough to make the bits extremely durable and wear-resistant. The HSS, on the other hand, makes the bits a good option for heavy-duty use.

Finally, if you are searching for a set of simple yet highly reliable drill bits, this set from Amoolo will be a good option for that role. These high-quality bits ensure a clean and hassle-free drilling process without compromises.
