When it comes to drill bits, all things aren’t equal. Made from a variety of materials and designed to drill through different surfaces, masonry drill bits need to be among the toughest of the bunch.
Often thicker, studier and longer than other types of drill bits, masonry drill bits have a slightly wider tip to help clear the path for the rest of the bit. In general, they’re best paired with a hammer drill, although depending on the surface you’re drilling into, and the size of the hole you wish to make, you might be able to get away with using a powerful standard drill. Note that, in our opinion, you’d be wise to spend extra on a drill bit from a known brand, since cheaper units can be prone to failure when the going gets tough. 36 Inch Saw Blade

The majority of masonry drill bits are made from tungsten carbide, a tungsten-carbon compound that resists abrasion well, and can withstand the high temperatures generated from drilling brick or concrete. Diamond-tipped bits are also available, but are usually way in excess of what a DIYer will need, both in terms of cost and specifications – although they’re the preferred choice for core drill bits.
Short answer: no. The most common kind of drill bits have a round shaft, and are suitable for the most popular drills; the kind of multipurpose drill that you’re already likely to have. They’re perfectly suitable for light to moderate work, and should be up to the job of drilling through most masonry.
Hex drill bits are a little more unusual. The hexagonal shaft will lock into a drill more firmly, and will resist twisting in the chuck. That ensures minimal torque is lost between the drill and the drill bit. However, SDS (slotted drive shaft) bits offer all the benefits of hex, but are designed for hammer drills. A deep slot in the SDS drill bit’s shaft locks in the hammer drill’s chuck for a secure fit that won’t loosen. SDS Plus has a 10mm shank, while SDS Max measures 18mm.
Regular masonry drills are available in diameters up to 25 or 30mm, but if you need to make a larger diameter hole – to run plumbing pipes through walls, for example – then you’ll need a masonry core drill bit. These large, hollow, cylinder-shaped bits have diamond-tipped teeth that effectively cut a circle in your masonry. Once you’ve drilled through, you’ll be left with the waste material inside the core bit. The beauty of core bits is that you’re left with a perfect hole, ensuring a snug fit.

Proving that a good set of SDS Plus drill bits needn’t cost the earth is this set from Wigan-based UK Drills. The SDS Plus set includes seven bits in five diameters and two lengths, presented in a robust metal case – which should shrug off damage better than the brittle plastic alternatives.

If you’re drilling through two courses of brick or a single course of blockwork, you’ll need a drill that will be long enough to avoid going through the hassle of having to drill through the reverse side. You’ll need to factor in the width of the bricks or blocks, the mortar, internal plaster and any external wall coverings such as render, plus the size of any cavities, too.
Fortunately, masonry drill bits that can tackle these types of jobs do exist, such as this 260mm-long drill bit from DeWalt. Featuring a two-cutter carbide head with individual cutting tips at 140 degrees for more efficient drilling, this lengthy drill bit has a hardened steel body to reduce the likelihood of breakage. Reviewers were impressed by the quality on offer here, especially for the price.
Key specs – Number of bits: 1; Material: Tungsten carbide; Sizes: 5.5, 6, 6.5, 7, 8, 10, 12, 14, 16, 22, 30mm

Hex drill sets suitable for masonry aren’t as common as those with a round shaft or SDS fitment, which probably goes some way to explain the popularity of this EZARC set. That, and the super-positive reviews it’s received from thousands of users.
There are five bits in the set, which come in two lengths – both of which are longer than is common at these diameters – and are stored in a plastic case. The tips are tungsten carbide, while the drill bit is made from hardened steel and features U-shaped flutes that are designed to efficiently sweep out debris from the drill hole.
