Our Top 5 Drill Bits for Metal

1. Bosch 25 Piece Metal HSS-R-Drill Bit Set

BEST PICK

Buy on Amazon

Bosch Accessories 2607019446 Bosch Accessories 25 Piece Metal HSS-R Drill Bit Set, Black

This Bosch HSS-R-Drill 25 piece bit set comes highly recommended and is the winner of our Best Pick because of its high quality and reasonable price. 

They are made of high-speed steel and are great at working with different materials. This is because the steel is able to maintain its temper as the bit continues to drill deeper. This is very important because bits made from low-grade materials tend to give in to the pressure and break. This is not one such product thanks to the high-grade steel design.

The Bosch HSS-R-Drill comes with 25 bits that will cover most of the diameters needed for projects. The various bit sizes give you options to work with every time you are faced with a new project without the need to invest in new sizes.

This product offers excellent cuts and comes well packaged in a metal protective box. The box will make certain that your bits stay put. They will be kept safe from the elements and from getting lost. For such an affordable price we do not see any real reason these could not ideal for home DIY projects as well as tradesmen.

For lubrication, during cutting, it is recommended that the Bosch coolant be used. These bits are durable and will provide you with value for money.

Pros

  • Comes with varied unbreakable bit sizes for more options as you work.
  • 25 strong bits from 1mm to 13mm for a range of drilling diameters.
  • Ideal for a range of jobs from drilling sheet metal to tougher jobs.
  • Includes sturdy steel protection case.

Cons

  • The box that comes with the bits is a bit flimsy and we think Bosch could of done better. Overall though, it does the job of keeping all the drill bits neat and tidy.

Our recommendation

We are overly happy with the Bosch metal HHS Drill Bit Set. They give you 25 bits for an affordable price so are within most people’s budgets.

The bits are strong enough to work through metal without going blunt but be sure you use coolant and go nice and slow, something we always recommend when drilling metal.

What we really like is that these drill bits offer excellent value for money when you consider you get 25 bits for the price. Overall these are great for lighter trade work and home DIY projects and will get the job done. For this reason, they won our ‘Best Pick Award’ for quality, performance and value for money.

However, professional tradesmen would be better off spending a little more and investing in the slightly better Sealey Cobalt Drill Set, which is very similar but slightly more expensive.

However, they are slightly stronger and would have won our ‘Best Pick’ award had Bosch not won bonus points for value for money and being more affordable. In general, the more expensive sets are of better quality, however, they are usually out of reach in terms of budget for most home DIY projects.

Drill Bits for Metal – Buyer’s Guide

Indeed, there are many bit manufacturers from leading brands such as Bosch, DeWalt and Sealey. To find the right drill bits for your drill there are a couple of factors to consider. The most important thing at the end of the day is to select drill bits that are compatible with your needs and the type and thickness of metal you are drilling.

How, do you ask? Continue reading below to explore more about drill bits designed especially for metal.

Types of metal drill bits

There are various types of drill bits available on the market. To facilitate an easy working environment for yourself. You need to understand the different types of drill bits and which have the ability to work through different materials with ease.

  • Split point – These types of bits are better suited for working with metals. The main difference between the split-point and twist bit is that one has better support features. The split point is designed to help maintain balance to the drill when working on difficult materials. The various drilling points are made sharper to facilitate a smoother cut.
  • Twist bit – This versatile bit can work with various materials. It is especially adaptable to metals but can be used on virtually any materials. It is, however, challenging to use the bit for precise drilling acts due to its high speed. It is also popularly known as the Morse bit.
  • Hole saw bit – Popularly attributed to cutting the smoothest holes. The design is to be credited to this. The circular saw cuts through as the drill feature holds the saw teeth for moving unnecessarily. They can be created to cut through different kinds of materials.

Purpose of drill bits

When you are on the lookout for drill bits, make sure that they suit the purpose. What hole size are you looking to create and what material you are working with. This way you can pick bits that have the right diameter and finish. There are materials that require a special bit, or bits that are only compatible with certain drills such as SDS Drills. Be sure to identify the function and compare it with what is on the market. If you aren’t sure about which works best with your drill, you can seek advice from many online forums or specialist retailers. In general, most drill bits fit the standard drills that most people have, all our top picks are designed to be used in standard drills.

Bit material

The bits can be fashioned from different materials in order to penetrate through various materials. There are those made from low carbon steel which is inexpensive and requires regular sharpening. Others are made of High-Speed Steel (HSS) that are great at working with metal, ceramic and wood. HSS drill bits are the most popular and can be purchased at reasonable prices. Carbide-tipped bits are among the most robust bits made. It can go through most available materials, even stone.

Additional accessories

There are manufacturers that give you extra features with your bits just to make the job easier for you. These extra features will cost you extra pounds, but they will not break your bank. Some of these features as mentioned include bolt extractors, extensions for wider and longer reach, amongst other things. Just make sure that you conduct your research to find out if indeed you need the additional features. These are usually included in larger sets, which our reviews don’t include because we are focusing solely on the best drill bits only.

Price of the bits

How much you are willing to spend depends on the work that you need to get done. There are bits that are sold separately simply because they accomplish a certain special function and are generally expensive so would cost a lot of money as a set. If you need a basic package of a few bits to get some work done, it is possible. There are those professionals who require an entire set of bits. These come at a different price depending on the manufacturer and more important the quality. Look at the budget that you are working with and decide. You can decide to buy the bits in stages until you get the whole set all though this can be more expensive. If you only need a couple of sizes, it can be cheaper to invest in just the sizes you need instead of shelling out on a set that includes sizes that you will probably never use.

In terms of prices, sets can range from £10 for a good set ideal for home DIY projects to over £50 for a decent professional set, specialist drill bits can even cost in excess of £20 per bit if not more. We found that a good set of around 10 drill bits would cost around £15 to £25 and would be perfect for most people.

Now you know what to look out for when purchasing drill bits, below is our Top 5 Recommended Drill Bits For Metal, which after looking at over 20 potential sets and doing many hours of intensive research, we have narrowed down to just 5, of the best sets which we think, are the best drill bits for drilling through metal.


Final Conclusion

Seeing that drills are not going anywhere in the near future. It is only feasible that all drill related features need to be top of the range. A powerful drill and powerful bits are a match made in heaven.

You will find yourself working with such pleasure that it might not seem like work anymore. Remember, the stronger the bit the more penetrative power it has.
