5 Best Drill Bit Set Options: Titanium And Cobalt Choices For The Most Precise Jobs

Drill Bit Set

Whether you’re working professionally with power tools, or are just a weekend DIY warrior, one thing you can never have too many of is drill bits. The problem is that there are so many bad products out there. They either won’t stand up to the demands of a busy job site. Or they just don’t give you the precision for your hobby cabinet making.

Obviously, you will need different types of bits for different materials you drill into. The most common types are for wood, stone and metal, and they all vary in the hardness of the bits themselves.

But even among the different types of bits, there are a huge amount of differences when it comes to quality and precision. You can really cheap bits that will work fine for basic around the house stuff. But if you’re going to be doing anything more than hanging pictures and setting up some shelving, then you’ll struggle make cheap products last.

To help you find the best drill bit set for your needs and budget, we have put together this list. It covers everything from commercial grade to affordable and durable home DIY use.

Our 5 Best Drill Bit Set Recommendations

1 – Irwin Tools: Cobalt M-35 Metal Index Drill Bit Set

If you’re going to be drilling in a lot of metal, steel and hardened alloy materials, then you need drill bits that will stand up to that demand. Allow materials are especially difficult to deal with and this Irwin Tools option is actually a very well priced product.

The drill bits have 5% Cobalt mixed in which is a metal that reduces the effects of friction and heat. When you’re drilling into metal, you will get a huge amount of friction and this will significantly heat up the drill bit.

Those forces will quickly do damage to the structure of the bits, unless you have Cobalt mixed in.

This set includes 29 bits which range from 1/16 inch to 1/2. This will cover the majority of common work tasks and you’ll find that you can get more work done with less breakage.

The split point is well designed with just the right angle to avoid “walking” on the metal surface. It will also require less pressure to get started, increasing the overall durability.

The main downside is that the hard case is quite difficult to open. This will take some getting used to, but it does keep the bits safe and tidy.


  • Cobalt drill bit set to reduce wear from heat and friction
  • Hard wearing makes them ideal for metals including tough alloys
  • ​29-piece set from 1/16 inch to ½ inch
  • ​Hard case with three bit holders to keep them safe and protected
  • ​Split point designed to limit the effect of walking on the surface


  • Case can be awkward to open
  • High price makes them less suitable for home use

2 – Mastercraft Titanium: Huge Selection For Different Materials

The largest set on this recommended list is the Mastercraft option here. All the bits are Titanium coated. This is an extremely hard wearing material that will increase the effective life of every single item.

There are a total of 230 pieces included. When you look at the price tag, that’s an exceptionally good value for money offer. You’ll be able to choose from designated bits for wood, metal and synthetic plastic materials. The only thing that they are not suitable for is masonry and concrete.

The storage box is excellent in that it keeps everything neat and tidy. And the hard casing also makes sure that they stay protected in transit and at busy job sites. The sizes are spread out from 1/16 inch all the way to 1/2 inch which does give a lot of flexibility.

But there are a few common sizes that aren’t included, so make sure you check out the product details at Amazon to make sure the exact sizes you need are included.


  • 230-piece titanium coated set for more durability
  • Sizes range from 1/16 inch to ½ inch
  • ​Great value for money given the versatile uses
  • ​Great for wood, metal and synthetic plastic materials
  • ​Heavy-duty storage case included


  • Not suitable for stone and concrete
  • Not all common sizes are included

3 – Bosch MS4091: Great Driver Combo Set

More often than not you’re going to use a drill and driver, or maybe a combo power tool. Having the ability to use one tool for drilling holes and the same one for driving screws gives you great flexibility at home and on busy commercial projects.

That’s why getting a combo set of drill and driver bits is an ideal solution. It’s something that belongs in every toolbox as it gives you so much flexibility. This Bosch drill bits fills that gap perfectly. There are a total of 91 bits included. And unless you need very large holes, you’ll likely be covered for the most common sizes.

They are also all titanium coated which makes them a lot harder wearing. You’ll notice that the sharp edges don’t blunt as quickly.

The drill bits are suitable for wood, stone and metal, so there will be very few jobs that you won’t be able to do. Just make sure you always pick the right bit for the job you’re facing.

The hard case is very well designed to keep everything tidy and in place. While in transport or at busy job sites you won’t have to worry about them getting damaged. There is even a convenient ratchet screw driver included.

The main downsides to mention are that some of the smaller driver bits can be very difficult to get out. You might need to use the extension to push them out. And for the drill bit sizes there is not a huge selection. So, check the sizes to make sure you have everything you need for your most common jobs.


  • Great selection of 91 drill and driver bits
  • Titanium drill bit set for more durability
  • ​Tough carrying case that will stand up to job site wear
  • ​Includes bits wood, stone and metal
  • Also includes ratcheting screwdriver


  • Difficult to get smaller bits out
  • Limited bit sizes

4 – Makita B-51661: Ideal For Contractors

Makita is one of the leading brands in the power tool and construction industry. And when you need a kit of drill and driver bits for use as a contractor then this 66-piece option is going to suit just fine. It’s the ideal combination of drill and driver accessories.

And what’s unique about it on this list is that it includes spade bits as well. These are ideal for drilling larger holes in wood and plastic. But how often have you needed one only to not find one in your tool bag.

The price for this product is very good, and you could even invest in two boxes to have some backups as well. The case is very well designed, as it comes with two trays. The bottom one can be used for additional tools that you commonly need to carry around.

And the smaller bits are stored in separate containers to avoid losing them. Or worse, they end up just flying around the case and you can never find what you need.

You’ll be covered for all types of materials including wood, stone and metal. But you do need to be a bit careful with the insert trays, as they are not the most hard wearing. And the smaller accessories can be very difficult to remove.


  • Large selection of drill and driver bits
  • Includes spade bits for more commercial job uses
  • ​Smaller bits are in a separate container for safe keeping
  • ​Hard case has multiple trays for storing additional tools
  • Provides a great range of uses for all types of materials


  • Insert tray is not the most durable
  • Some bits are difficult to get out

5 – DEWALT DW1361: Titanium Pilot Point Drill Bit Set

This set of DeWalt products is probably one of the best value options you could invest in. You won’t get a brand name product at this low a price with the quality associated to this company. This set is fully titanium coated which makes them a lot harder wearing.

You will be able to drill through metals like steel and wood with easy and confidence that they won’t wear and break every couple of minutes. Even tough alloy metals can be dealt with relative ease.

The set is made up of 21 bits ranging in size from 1/16 to 1/2 inch. For the majority of hobby and even commercial work that will be more than enough to keep you going.

The split tip is design to reduce “walk” on the surface by an absolute minimum. This will give you a lot more precision with less effort involved.

And with a tapered web design you have a significant reduction in the risk of the bits snapping. Even if you apply a lot of pressure, you won’t find them snapping too easily.

The main downside is the case. The bits tend to be very lose inside and once opened have a tendency to slip out. Just something to keep in mind and get used when you’re opening the case.


  • Titanium coated for very hard wearing durability
  • Includes 21 bits from 1/16 to ½ inch size
  • ​Will work on all types of metal including alloys
  • ​Excellent design to reduce walk and slipping
  • Tapered web design reduces risk of breaking


  • Bits are a bit loose in the case
  • Case is a bit awkward to open

Features You Should Focus On

To help you better compare products from different manufacturers, we have put together this section. These are the main features that you should focus on to make sure that you get the full benefit. Only when you understand what your top priorities are, can you make sure you don’t get blinded by fancy marketing materials.


The first thing you want to look at is what size holes you will most commonly need. All of the above products come with wide ranges of size. But if you have specialty sizes, or you need a very precise hole, then always make sure that the kit includes what you need.


You also have to consider what you’re going to drill into. This will impact the type of drill bit you need as materials like stone and steel require a different design and material on the cutting edge.

The tip will also be very different. On metal drill bits you’ll notice an almost needle like split that help to reduce the amount of walk you get on the surface.

You also want to take a look the materials used to make the bits. If you’re going to be doing a lot of drilling in metals and alloys, then you need something that is incredibly hard wearing. At the very least you’ll need a titanium coated product. But for lots of metal drilling you’re probably better off with something that has 5 to 10% Cobalt mixed in.

This metal will reduce the effect of heat and abrasion, increasing the amount of work you can get done with each bit.

Storage Case

It’s very important to keep you gear and accessories safe at all times. Most often things break when they are being transported. So, make sure you have a decent carrying case. This should also keep everything tidy and organized so that you don’t end up searching for the right size every time.


At this stage you have all the information you need to choose the best drill bit set for your personal needs. Whether you just need it for occasional home DIY jobs or for professional jobs, you’ll find something above that will suit you needs.

You have everything from wood to metal drill bit set covered, and even some driver combo kits as well.
