If you are on the hunt for the perfect drill bit when it comes to hardened steel, look no further. Since there are so many on the market to choose from, we realise it can be difficult to separate the wheat from the chaff.
Drill bits that are specifically designed for a certain material are a necessity for any handy person, whether you are drilling wood, walls or metal.
If you are considering some new tools to add to your kit, we are going to tell you what the best drill bits are for hardened steel.
To start with, we will provide you with a list of the top five drill bits that are suitable for hardened steel.
This list will be based on certain categories and criteria that we think are important for drill bits to fit into.
There will be an in-depth description of each product on the list. Some pros and cons of each product will follow the descriptions to make the comparisons easier for you.
To follow this initial list, there will be a buyers’ guide that will break down the important things to consider when buying drill bits designed for drilling hardened steel.
In at the top of our list is the first Bosch drill bit set. This is a set of 19 drill bits that are designed specifically to drill holes through materials such as alloyed and non-alloyed steel, as well as cast steel and cast iron, sintered iron, malleable cast iron and non-ferrous metals.
The ‘HSS’ in the name stands for High-Speed Steel, meaning that drilling time is reduced by up to 40%. So, this drill bit set is perfect for your metal drilling needs. These drill bits have a split-point tip that allows for active cutting and excellent precision when drilling through metal.
You can drill your project without the need for a pilot hole thanks to this split-point tip. The drill bits have an exposed 135-degree self-centring tip that allows for a smoothly drilled hole without fear of wandering.
This set of 19 drill bits also comes in a handy and practical carry case, making this product easy to store in your ever-growing DIY tool kit.
Sizes of drill bits range from 1mm to 10mm in diameter.
Split-point tip means a reduced drilling time.
Practical carry case to keep your new drill bits safe and dust-free.
Designed to drill through alloyed steel.
This drill bit set has an energy class rating of A.
Some of the drill bits have been reported to be brittle.
The second on our list is another Bosch set of drill bits. This time it is a set of 7 multi-purpose silver drill bits. These are perfect for drilling concrete, brick, wood, and most importantly, steel.
Bosch even claims that these drill bits will drill through steel without the need for hammer action from your drill, but that better results will be seen if you do.
They are made from tungsten carbide metal that is durable and has a fine grit for better performance. The set that you can find on Amazon comes in a case where you can keep your drill bits for storage convenience.
The size range of these Bosch multi-purpose drill bits spans from 4mm to 12mm, making this set reasonably versatile and able to cater to many of your metal drilling needs.
For a 7-piece drill bit set, there is a reasonable range for sizes available.
The carbide metal material has a fine grit that will give you great results.
You don’t necessarily need to use the hammer function on your drill.
The cassette that the drill bits come packaged in is not as sturdy as some of the others on this list.
Next on the list is a 100-piece set from DeWalt. Not all 100 pieces in this set are for use with a drill. It is a mix of drill bits and screwdriver bits, so there is even more reason to have this versatile kit in your tool kit.
All of the pieces in this set come in a sophisticated black and striking yellow tough plastic carrycase for simple and effortless storage in your tool kit. All of the included pieces have their own set place in the case and are spaced out evenly for easy access when you are working on your project.
The set includes 12 metal drill bits that range from 1.5mm to 6.5mm in diameter, as well as drill bits specifically designed for masonry and wood. Since this set includes specific metal drill bits, they are designed to withstand drilling through metal more so than a multipurpose drill bit.
The point angle of the tapered tip on each of the drill bits is 118-degrees, this reduces the risk of a wandering drill bit when you are drilling a hole.
The benefit of buying this drill set for the metal specific drill bits is that you are also receiving drill bits for other materials, as well as magnetic screwdriver heads.
Comes in a tough carrycase that makes it easy to store your new drill bits.
Includes 12 drill bits that are specifically for drilling metal, and therefore steel.
The point angle of the tip is 118-degrees, reducing wandering drill bit.
If you want just the metal drill bits, you also have to buy the other parts that come with this set.
Coming in at fourth on the list is another from DeWalt. This time it is a 10-piece set, so is easier to slot into your DIY kit if it is already extensive and you do not need the 100-piece set above.
All of the ten drill bits in this set are specially designed with drilling metal in mind.
They come in a bright yellow cassette for convenience of storage, it also looks professional in your kit. The sizes of the drill bits range from 1mm to 10mm in diameter, increasing by 1mm each increment.
HSS stands for High-Speed Steel, so you can rest assured that these drill bits are sturdy and designed to reduce the time it takes you to drill through steel and other metals.
Includes a plastic case that keeps your drill bits tidy when stored away after use.
There are 10 drill bits that range from 1mm to 10mm, increasing in 1mm increments each time.
A patented split pilot point keeps the drill bit from slipping when in contact with the metal you are drilling.
No 0.5mm increments like some of the others on this list, meaning you cannot get a precise sized hole should you need 5.5mm for example.
Last on the list of our top five drill bits for hardened steel is the S&R Set.
This is 19-piece set of drill bits specially designed for drilling metal such as hard alloys, cast metals and stainless steel. Like a few of the others on this list, the S&R drill bits are also HSS (high-speed steel) with a 5% cobalt alloy.
The point angle of each drill bit is 135-degrees, so your drill bit will not wander when you are trying to drill any hard metals. This set of drill bits is compatible with hand drill and pillar drilling machines from many brands including Bosch, DeWalt, and Hitachi.
The sizes of the drill bits range from 1mm to 10mm in diameter, increasing in increments of 0.5mm each time.
The case that these drill bits come in is made of blue metal, so you can rest assured that your new drill bits will be protected when you store them with the rest of your DIY supplies.
The point angle is a generous 135-degrees of each of the drill bits, so you won’t need to worry about the drill bit slipping when you are trying to drill into metal.
Includes a sturdy and practical metal storage case that perfectly holds all of the different sized drill bits in place.
The range of size increases in 0.5mm increments from 1mm to 10mm for all 19 of the drill bits.
Some buyers report that it took them a while to drill through their desired metal with these drill bits.
Best Drill Bits for Hardened Steel – Buyers Guide
In this section, we will lay out all of the important categories that we think you should consider when looking for drill bits that will work with hardened steel. In each category’s section, we will tell you whether each of the five products fits the criteria or not.
A carry case or cassette is something that you should consider. If you don’t already own a storage solution for your new metal drill bits, you may want to buy a set of metal drill bits that come with a sturdier case, since storing them loose could damage the tips.
All of the five products that we have listed come with a case or cassette of some kind. The Bosch Multi-Purpose Drill Bits comes with a full carry case since there are 100 pieces in the kit, whereas the DeWalt Jobber Metal Drill Bit Set comes in a plastic cassette since there are only 10 pieces included.
You can still use the cassettes as prolonged storage for your drill bits, but the carry case of the Bosch Multi-Purpose Set and the metal case of the S&R Metal Drill Bit Set are going to last you for a longer period of time since they will stand up to more DIY related wear and tear.
When buying a set of drill bits that are specifically for drilling into metal, you might want to buy one set and then not have to worry about buying any more add-on accessories. Because of this, we think that looking at the size range in the set is important.
Your own size needs could be completely different to someone else’s, but we think it is important to have a reasonable range of sizes. obviously, the drill bit sets that have more pieces in this list are going to have more size range.
However, which set you buys depends fully on whether you need a large size range or a size range of drill bits that increases in smaller increments of diameter each time. In our top five, we have included a range of the two types of size ranges when it comes to drill bits.
Tip’s Point Angle
Another important thing to consider is the point angle of the tip of each drill bit. This angle will determine how hard or easy it is for the drill bit to slip and wander when you are drilling. the greater the angle, the less likely this is to happen.
Both the S&R Metal Drill Bits and the Bosch HSS-G Drill Bits have a point angle of 135-degrees, greater than the 118-degrees that the DeWalt Drill Bits can offer. This might be something to consider when you are buying drill bits, especially for metal, a material that drill bits can naturally slip on.
Now that you know more about each of these top five drill bit sets that are specifically designed for metal materials, we hope that you can pick your best option out of the five.
Although we have ranked them and picked a top set, your needs might not necessarily match up to that.
Judging by out buyers’ guide, decide which drill bit set your projects would benefit from you buying. Hopefully, this buyers’ guide helped you on your DIY journey!
