Features To Consider With Drill Bits
These drill bits offer a variety of useful and reliable results, but if you’re unsure about which drill bit options are right for you, check out these essential key features to consider so you can purchase the ideal set with confidence.
There are many types of drill bits to look for, so it’s vital that you understand the best type for you. At first glance, it can be achingly overwhelming to search through the myriad of drill bits available. However, while there are many (and we mean many) drill bit types, the average hobbyist is unlikely to need more than a select few.
These are twist bits, masonry bits, countersink bits, hex bits, and flat bits. All are suitable for your everyday drilling needs, while many will offer something more versatile. Even if you don’t use them regularly, they are still useful to have at your disposal, as it will save you a trip to the hardware store to stock up, especially if you only need a single bit to finish a job.
Picking the right drill bit will save plenty of time and energy, and they will also ensure it does the job correctly. We cannot stress how crucial this is, as you don’t want to use an alternative drill bit and make a mistake or find the hole you make is not suitable for the job.
There are two primary drill bit materials you will encounter. These are steel and cobalt steel alloy. Drill bits that use cobalt are more durable and heat-resistant, which gives you peace of mind when using them for demanding jobs. They are also less prone to damage and therefore boast increased wear resistance that will ensure quality performance and results.
Steel bits are often referred to as titanium bits, although this is because of the coating (which we’ll get to in a minute). These bits are not as durable as their cobalt steel alloy counterparts, but they are still useful for softer materials. However, it is vital to know which materials they are not compatible with, such as stainless steel, as this could cause severe damage to the bit and ruin your project before you have even gotten started.
The most common drill bit coatings are titanium nitride and titanium carbonitride. These are used to provide better wear-resistance for regular steel drill bits to increase longevity, although it will still wear away faster than cobalt bits. Despite this, titanium coating for titanium bits is ideal for prolonged repetitive tasks and they can cut through some metals, wood, and plastic.
Another coating you are likely to come across is Black and Gold Oxide. This coating doesn’t deposit on the surface, keeping the area clean, and it is not so thick that it affects the quality. Such a design is especially useful for more precise drilling needs, as you have to ensure your small drill hole is the perfect size to guarantee exceptional and trustworthy results.
Numbers In The Set
You might expect that the more numbers in the set the better, but this isn’t always the case. While it might seem convenient to have as many drill bits as possible and include a broad range of bit styles, including those for a brad point drill, twist drill, it can confuse novices and even be a waste of money.
If you only use a few drill bits, such as those with split point tips or for a hex shank drill, you don’t need a comprehensive number of drill bits. Instead, it is better value for money to only purchase the number of drill bits you can envisage using, especially at first. However, if you’re a professional craftsperson, you may need an extensive set to accommodate the range of jobs you have.
The most common size specifications you will find when searching for drill bits will be in fractional measures. The smallest will be 1/64-inches, while the biggest will be 1/2-inch or 3/4-inch, depending on the style and brand. Despite this, there are specialized drill bits that will provide a broader range, and these are the best choice for professionals.
Much like the number of bits in the set, you are unlikely to need everything, but approaching it with a more the merrier attitude can significantly increase your success and scope when performing DIY projects. Again, novices are best off looking for the standard size spec range, but professionals may want to increase their potential by getting as wide of a range as they can to maximize the opportunity for getting a job done the first time.
Choosing the right bit for the right drilling material guarantees a straightforward and successful project. For example, a masonry drill bit is best for drilling brick. Likewise, twist bits are best for regular steel, while cobalt steel bits are better for hardened metals, including stainless steel and cast iron.
Ideally, you want a drill bit set that includes as many drill bit types as possible. Most sets will come with enough variety to drill metal and wood, but you may need a specialized set, such as those in a hex shank style that will fit securely in your drill driver. Even professionals who typically only work with a single drilling material can benefit from purchasing a set with some variety that will also include driver bits, as you never know what you might encounter while on the job.
Drill Bit FAQ
Q: Is cobalt or titanium drill bits better?
Cobalt and titanium drill bits are both popular styles for professionals and hobbyists. However, there are several differences between them, and this can help you determine which type of better for your needs.
The primary difference is the material. As the names suggest, a cobalt drill bit is made from a combination of cobalt and steel alloy. Conversely, titanium drill bits are not made only from titanium, but instead from steel. They are then coated with titanium carbonitride or just titanium nitride.
This is not the only difference, however. The titanium coating for drill bits will wear over time, exposing the steel, and affect the impact and heat resistance. Cobalt bits are more durable, as they have been designed specifically for heavy use. Although they may cost slightly more, the durability can represent better value for money overall.
Despite this, you also need to consider the material you are working with. Titanium drill bits are better for soft materials, such as wood and plastic, and softer metals. Cobalt bits provide heavy-duty performance and are suitable for cast iron or similarly tough metals. With this in mind, neither drill bit is better, but there are styles that are more suitable than others depending on the material and scope of the job.
Q: What are the best bits for drilling steel?
While there is a range of materials, one of the most common is steel. We've already highlighted that cobalt is best for cast iron and robust metals. As stainless or hardened steel can fall into this robust category, cobalt drill bits are arguably the best types for steel.
But it's not enough to just say so. We need to understand why cobalt drill bits are ideal for steel. The angle of the drill bit plays a significant part in making these bits suitable for drilling steel. You'll need bits with 135-degree split points as this will give you a consistent drilling speed that will glide easily through the steel.
If you want to make things easier, you can add some oil to the metal which will keep the bit cool and prevent heating issues. A wooden block placed underneath the steel is also useful, as this will prevent damage to the surface below. While cobalt bits are highly durable, there is still a risk of dulling the end if you are not careful. If you do this accidentally, you can still sharpen the bit end to get it back to the ideal sharpness and ensure exceptional efficiency when drilling steel.
Q: Are drill bits interchangeable?
Interchangeable drill bits sound like a no-brainer. Surely manufacturers and brands would want their drill bits made so they will fit in as many power tools as possible. Of course, it’s never that simple, and not all drill bits are interchangeable. While disappointing, it's vital to know this before you tear down the house and start anew, only to find your 1/16-inch drill bit won’t fit in your power drill.
It can appear confusing, but it need not be. As long as you know the size of your drill shaft, you can choose the right drill bit size to ensure seamless changing and allow you to cover as many jobs around the house without investing in a new tool.
A drill shaft that measures 1/2-inch size will accept drill bits up to 1/2-inch. Likewise, shafts measuring 3/8-inch are only suitable for bits of the same size or smaller. This sounds simple enough, but there are further complications. For example, hex-shanked bits are not compatible with an impact driver, although they will fit in a regular drill.
You should also consider which sizes and types are suitable for the material you're using, as not all drill bits are interchangeable with all materials. Brad-point bits are suitable for metal, wood, and plastic, for example, but they may not be suitable for brick or concrete, which may require a heavy-duty drill bit to fit the drill driver.
