DEWALT DWA1240 Pilot Point Industrial Cobalt Drill Bit Set (14 Piece)
These set of bits are very cheap but we won’t go as far as refereeing to them as the “El Cheapos” in the market. They are however the best overall ‘value’ option on our list for everyone who is on a limited budget.
These bits will serve you effectively well if you require a small set to perform a single project or just a single job. Do you have a piece of ⅛” angle iron that you can pop some flathead screws into? They will do the job with ease- don’t just expect them to perform that task a 100x over.

These bits are simply put the direct rival/competition to the Drill America set as they are equal in almost every aspect. They are made from the same materials, contain the same number of size increments and sizes and operate the same way. Any superiority between the two is negligible.
The Drill America set gets out top pick over the Irwin set due to the price which is 25% less and also, we discovered that they compete favourably with each other based on quality and performance. But hey, if you love buying household names then these bits will work perfectly for you.

Most retail stores and online shops will not appropriately inform you of what is best to satisfy your needs. Often times the much needed details are not put in plain letters. You consequently need to do your personal research to discover what suits your specific needs. Even though this product appears simple and straightforward, there is need for you to be well informed before going to the market. Check out some key features we consider before buying our drill bits. These will assist you in buying the perfect one that suits your needs.
Look at the Material Your Drill Bit Set is Made With
For metal drilling operations, your drill bit’s material construction is very important. You cannot effectively drill a hole if you tool material is not good enough. A very good example is the HSS drill bits which are very hard, durable and are able to effectively drill at high speed.
The very best metal bits are made of cobalt and steel. They are characteristically hard and do not fail while drilling very thick metals. Furthermore, there are those that are made of High-speed steel (HSS) which have a rigid design but shatter under intense drilling. These are suitable for you if you work on metal sheets and thin metal planks.
What Will You Be Drilling into?
Given that, you have discovered this review, it is obvious you are in search of a tool to drill into metal. There are however different types of metals. Thus, the specific type of metal you are working with is important to make you purchase decision. A thin drill bit would be sufficient for you if you want to drill through thin metal sheets while if it’s thick sheets you will need other types of drill bits. In addition, if you are in search of metals that produce heat, some drill bit models also meet this need.
Look for the Numbers in a Set
Let us assume that you have a considerable budget and are willing to acquire the full set of metal cutting drill bits. Now what? At this point you need to compare the number of bits available in each set. Our advice is to compare the particular model you want to buy with its options. Surprised? A few modes sport different packages based on the number of bits in them.
You may also like to compare between the various brands for the number of drill bits. Simply put, a higher number ensures that you are able to do several types of drilling operations with the product. Professionally speaking, I would most certainly pick a product with the highest number of drill bits because they are versatile and provide multiple options when drilling holes of polishing things.
How Often Will You Be Drilling Holes?
The project you are working on matters a lot. While most folks drill into wood materials some others drill into metal for their DIY project during the weekends. These people are warriors to us others are just hobbyist. While the latter may occasionally drill into thin metal sheets the former are the pros. They work on metal materials of all thickness and as such are very serious handymen. They work with different hole diameters and also polish metals for different applications.
There is a drill bit set for each category. These sets are specifically designed to cater for one or multiple operations. It is essential that you figure out your work pattern before purchasing a particular product. You do not want to buy an item that is useless and idly sits on your shelf.
To arrive at the best price you need to fully understand the projects, responsibilities and the frequency of drilling operations involved which will ultimately help you decide on the ideal drill bits to use. Also if you are in search of a product that retains it quality over time, it is advisable to go for the ones that are very durable and adaptable.
The bits that are coated with Titanium and cobalt are my personal favourite as they provide the best results. Even though they are fairly high end tools with a hefty price. Acquiring these high-end tools is really great but not always necessary especially when you are on a low budget. Ultimately, mid range drill bits can effectively perform in such cases.
In general, the Drill America 29-piece Steel Jobber set is still remarkably the best drill bit for steel as far as we are concerned.Based on factors like best all-round performance, price, durability and overall value nothing comes close to this drill bit set over years of comparing them. They sport a beautifully crisp, savage bit which drills into the hardest metals and is able to stand up to loads resist abuse before requiring being re-sharpened
