A good drill set is an important piece of kit for DIY enthusiasts and tradesmen alike. But you can’t just stick any old drill bit onto your drill to drill your perfect hole.

Now, if you’re looking for a really extensive and comprehensive drill bit set, this would be the one to go for.
It has a whopping 246 individual pieces, and this is composed of 57 pieces of HSS titanium-plated drill bits, 21 pieces of masonry drill bits, 17 pieces of twist wood drill bits, 4 flat wood drill bits, 30 pieces of HSS black oxide drill bits, 90 pieces of screwdriver bits, and 4 pieces of drill stopper.
The HSS titanium-plated drill bits are really long-lasting but may require a coolant when in use, whereas the black oxide drill bits have better heat resistance. Black oxide drill bits are ideal for hard and soft metals, whereas Titanium Drill Bits are excellent for drilling wood, metal, fiberglass, and PVC.
The screwdriver bits include metric hex, slotted, star, posidrive, and phillips varieties.
You also get hole saws, nut driver bits, a cupped nail punch, a spade bit extension, an Arbor adapter, a magnetic bit holder, and 2 Allen keys.
The advantage of having such a wide range of drill bits at your disposal is that you will never have to settle for the diameter closest to the hole size you want to make, you’ve got a much greater chance of having the exact size you need, down to the nearest 10th of a millimeter diameter. You simply can’t get better precision than that.
Customer feedback is very positive, with an average Amazon customer rating of 4 stars of out 5 after well over 400 ratings.
But if that doesn’t give you quite enough confidence, check out the guarantee that comes with it – it lasts for a full 2 years.

On the manufacturer’s website, there is no indication as to what these drill bits are made of (apart from the HSS ones) or what they’re coated with, so the only way to evaluate them is by customer feedback
This is not Bosch’s usual price point, and they do have higher quality drill bits available at higher prices.
It’s a really good idea to buy a comprehensive drill bit set that you know will cover everything that you might want to use it for. So a drill set that covers through wood, masonry, and metal would be a really good buy. All of the sets in our Top 5 picks will drill through all of these.
That said, if you want drill bits for just one of these purposes, you can certainly just get what you need, and then you can look more closely at things like what the drill bits are made of, or are coated with, and how they are designed to best suit what you need it for.
So you can get drill bits designed to bore through wood, drill bits for masonry, drill bits for metal, and drill bits for glass and tiles. You can also get general-purpose or universal drill bits that can be used in wood, metal, plastic, and many other materials. These are the most commonly produced and are known as twist drill bits.
Metal Drill Bits
The main types of metal drill bits are HSS, cobalt, titanium, and tungsten carbide. They don’t all perform equally, and you will need to select the best drill bit for what metal it is you want to drill through.
One of the more common twist drill bits is the HSS drill bit. HSS stands for High-Speed Steel. They are made from carbon steel with the addition of other elements such as chrome and vanadium. As their name suggests, their make up enables them to be used at high drilling speeds.
HSS drill bits are the most versatile type of drill bit. They can be used to drill plastic and many types of metal, such as iron, steel, brass, copper, and aluminium alloy. Although they can also be used for wood, they aren’t specifically designed for boring through wood per se. What they cannot be used for is masonry, glass, and tiles.
There is much variation in HSS drill bits, they differ in how they are manufactured and have different degrees of hardness and durability.
Masonry Drill Bits
Most masonry drill bits are made from tungsten carbide, and these tungsten carbide drill bits will drill through concrete, granite, sand-lime brickwork, and natural stone.
The quality of a tungsten carbide drill bit comes down to the quality of their point and the number of cutting edges they feature, the more the better. Concrete drill bits usually also feature a fluted design on the tip to facilitate dust removal. They differ in their shank design and can have a straight shank or a slotted drive system SDS.
Wood Drill Bits
Most wood drill bits are made of tempered steel. There are 2 main types: flat wood bits, which are typically used for drilling large holes upwards of 13mm, and twist bits, which typically have diameters going up to about 17mm. Twist bits are better for drilling through thicker woods, while flat bits should be used for thinner woods.
In a wood drill bit set, you may also find auger bits, which are specially designed for removing shavings while drilling wide holes.
Frequently Asked Questions
Is cobalt or titanium drill bits better?
What type of drill bit you need comes down to what it is you want to drill through.
If you’re going to be working exclusively with harder metals, like stainless steel and cast iron, then you’ll be better off with a cobalt bit, since it has superior durability and you can sharpen it.
If you’re only going to be working with softer metals and wood however, then you can’t go wrong with a titanium drill bit.
What are the hardest drill bits?
Carbide is the hardest drill bit you can get, but unfortunately, it’s also the most brittle.
