Clickmetal are the UK's premier suppliers of aluminium and stainless steel pieces. Read on for our step-by-step guide to drilling through metal precisely, from choosing the right drill bit to deburring the hole.

Drilling through masonry can be tough, requiring special drill bits for concrete that will hold up to the job. We recently tested seven different types of concrete drill bits in various sizes—using them to drill holes in concrete, brick, and stone.

Each bit has a wide spiral flute that bores evenly through stone, concrete, and brick. These bits will easily handle tough concrete-drilling jobs, but you’ll want to use a good drill for concrete—and it will need to be a rotary hammer drill with a minimum 7/8-inch chuck. We drilled several holes in quick succession, and the Makita bits performed flawlessly.

With extra-wide U-shaped flutes, these drill bits from WorkPro effectively ejected masonry dust as we drilled in concrete, brick, and stone. The bits have Luxembourg carbide tips that are made to be tough, hard, and durable, and they drilled quickly in our tests.

We tried out a 1-inch hole bit, although these bits are available in several sizes to suit your specific needs from just under 3/4 inch to 4 inches in diameter. This is a diamond-coated drill bit; tiny diamond shards are laser welded to the tip, making it easy to drill through concrete and other types of masonry.

Masonry drill bits come in several variations, including rotary percussion, double flute, and saw drill bits. All bit types use large carbide tips that can penetrate stone. Some bits have spear-shaped tips that allow for precision drilling, while others feature a crown-shaped tip that can efficiently grind through masonry.

In addition to drilling through masonry, we tried out this set of bits on dimensional lumber and 8-gauge sheet metal. They were slightly slower on masonry than some of the dedicated bits we tried, but they still did the job. They excelled as drill bits for metal as long as we drilled nice and slow. It’s not every day you can pick up a set of good metal drill bits and use them to drill a hole in brick or concrete, but it’s possible with the EZArc bits.

This set from Owl Tools includes 10 drill bits at an affordable price point. With its broad range of sizes, this set can handle most concrete drilling needs; bit sizes range from 1/8 inch to 1/2 inch in diameter, and we found them all to be durable and of good quality.

You can drill as soon as the concrete is completely hardened, but pros often wait a couple of days to ensure the concrete is ready. Unlike needing to wait before painting or applying a sealer, you don’t have to wait 28 days to drill.

We strive to process all orders for despatch within 3-5 working days from receipt. The order will then be dispatched via a 24 hour courier on the next working day.

Trying to drill into a piece of metal without securing it is a recipe for disaster. If the drill bit catches, it could cause the metal to spin around violently, slashing at anything and anyone in the vicinity.

Like higher-end bits, this set of Owl Tools bits comes with pointed tips to help keep the bit positioned when starting the hole. We tested the bits by drilling into brick, concrete, and stone, and they fared well. We felt they were just slightly slower than some of the other bits we tested, but drilling into masonry isn’t something to hurry along. We mainly wanted to see if they could withstand repeated drilling without breaking, and they did.

Safety always comes first. As with any construction project, it’s important to take steps to protect yourself from injury.

A durable hard-plastic carrying case keeps the bits organized and easy to transport to the worksite. It was one of the better cases we saw, as it held the bits securely and came with a sliding lock. This is an all-around great little set of drill bits for anyone who regularly needs to drill into concrete or other masonry materials.

The following drill bits are well suited for drilling into concrete and other masonry materials. They withstood rigorous hands-on testing, and each set of bits performed well enough to make our list. You’ll find different sizes and types that fit different drills. There’s sure to be one for your concrete-drilling project.

To cover all bases, we tested bits that fit standard drills and impact drivers, as well as rotary hammer drills. We also tested a hole bit that fits a grinder.

Some drill bits have coatings to improve their performance. Black oxide coatings are more durable than high-speed steel, as they resist rust and corrosion. Tungsten carbide coatings enhance the drill bit’s strength, enabling it to bore through stone and concrete.

Masonry drill bits need to be hard enough to endure the rigors of drilling through concrete. With that in mind, most masonry drill bits have steel shafts with a cutting tip made of tungsten carbide, which is much harder than steel and can grind through stone without dulling quickly. Some drill bits use diamond particles, which are welded to the cutting edge to chew through hard surfaces such as marble and granite.

We liked the pointed tips on this set of bits as they kept the bit from skittering across the material when we started drilling, which made the process much easier. If you need to drill different size holes in masonry, these Bosch Bulldog bits are just the ticket.

Before selecting the concrete drill bit sets we wanted to test, we researched more than 20 sets, looking for high-quality bits made from steel with carbide tips. We considered brand to an extent—after all, manufacturers like Bosch and Makita have top reputations for producing high-end power tools and accessories. Still, we didn’t automatically eliminate smaller or niche manufacturers if their masonry drill bit sets were highly rated by customers.

Start by drilling a small guide hole at a low-speed setting for very hard concrete. Once you’ve established a 1/8-inch hole, remove the bit, blow the dust out of the hole, and use a larger bit at medium speed while applying steady pressure. It’s also a good idea to wear hearing protection—concrete drilling can be loud.

Our extensive selection includes both standard and custom products. We supply to businesses and individuals throughout the UK, and manufacture all our pieces on-site in our state-of-the-art processing facilities.

When purchasing and using a drill bit for masonry, there are several important guidelines to follow to ensure a successful outcome.

The Owl Tools bits have standard smooth shanks to fit a regular drill. We didn’t notice any of the bits slipping as we applied pressure while drilling, as some smooth-shank bits tend to do.

Masonry drill bits are specifically designed to tackle stone and can bore through these hard surfaces with ease. Often featuring tungsten carbide tips that can endure drilling through hard stone surfaces, masonry drill bits have wide flutes that allow them to pull away large amounts of material as they drill to prevent debris from jamming the bit. Some bits even use diamond-encrusted blades to cut through this material. They come in a wide range of sizes to suit different needs.

Clickmetal is a specialist in the online supply of stainless steel, galvanised steel, mild steel and aluminium. We cut all types of metal to size and supply across the United Kingdom to both trade and domestic customers.

The final step is to neaten and smooth any rough edges within the hole. You can use a specialist deburring tool for this, or you can use a drill bit that is slightly larger in diameter than the hole you just drilled. Twist it by hand over the top of the hole to grind away any burrs left over.

This set comes with five bits, ranging in size from 3/16 inch to 1/2 inch. An included plastic bit case provides convenient storage.

While there is no single chuck or drill head for concrete bits, many concrete bits have a slotted drive system (SDS), which means they have slots on the ends of the shanks for use in rotary hammer drills. SDS bits came out decades ago, and today, an improved version (SDS-plus) is standard on bits for hammer drills. You can still find smooth-shank bits for standard drills and hex-shank bits that will fit standard drills and impact drivers.

When using a metal piece in your project, you may need to drill into it at some point. Metal’s harder composition makes getting a clean, precise hole more difficult than drilling through wood or masonry, so there are a few things you need to consider before you get started.

Masonry drill bits come in a variety of sizes to suit a broad range of needs. The smallest masonry bits are around 3/16 inch in diameter, with larger bits topping out at the 1/2-inch size. Hole saw bits have sizes that go up to 4 inches or more.

The SHDIATool core bit excelled in our tests. To extend its useful life, users can spray the surface of the material they’re drilling with water, which will help keep the bit cool and reduce friction. This is the bit to have for drilling larger holes in concrete.

Gloves, loose clothing, and long hair can get wrapped up in the drill bit as it spins, risking serious injury. Avoid wearing anything with hanging parts and keep long hair securely tied back.

For most standard bits, you don’t need to use water. However, if you’re using a large hole bit, spraying the surface of the concrete with water can reduce friction and help keep the bit cool as you drill.

A durable hard-plastic storage case keeps the bits organized and protected when in a tool box or on the workbench. Thanks to the visual holes in the holder that show the exact size hole each bit will drill, we found it easy to pick the correct-size bit at a glance. If you regularly drill into any type of masonry, you won’t go wrong with this set.

Repeated drilling through dense concrete and stone puts drill bits to the test, often wearing them down quickly. While these drill bits from Makita are more expensive than some masonry drill bit sets, in our tests, their thick tungsten carbide tips held up well for drilling several holes.

This is the second set of Bosch drill bits to make our lineup, and we found these bits highly efficient. Their four-flute design excelled at ejecting dust and debris as we drilled, which made the drilling process smooth and quick. Their pointed tips kept the bits centered as we started the holes. We were able to drill clean holes in concrete, brick, and even dense stone without problems.

When buying any type of drill bit, it’s important to consider its compatibility with the drill. Not all drill bits fit all drills. A 1/2-inch-size drill will fit drill bits with a shank up to 1/2 inch in diameter, while a 3/8-inch-size drill will only fit drill bits with shanks up to 3/8 inch in diameter.

Our favorite, thanks to its four-flute design and carbide tips, is the five-piece Bosch Bulldog Carbide Set for use in hammer drills, which are often used as masonry drills.

These are slotted drive shaft (SDS) bits, meaning they will fit SDS-plus hammer drills, so we used a cordless Milwaukee rotary hammer drill for testing. This set has five pieces, including a 3/16-inch, 3/8-inch, and 1/2-inch bit and two 2¼-inch bits of different lengths. The carbide tips are rugged, and we could easily drill through concrete, brick, and stone.

Most masonry drill bits are used in hammer drills or standard drills, but not all. The SHDIATool core bit is designed for use with an angle grinder, and we were impressed at how well it drilled.

The bits feature SDS-plus shanks, and users will need a hammer drill to use them. The set comes with seven bits, ranging in size from 3/16 inch to 1/2 inch in diameter, making this a highly versatile set of masonry bits.

It’s not unusual for your drill bit to shift when you first start drilling. This could cause the hole to be strangely angled or in the wrong place, so it’s a good idea to create a ‘dimple’ in the metal first.

In addition to carbide tips, the EZArc bits have multigrind sharp edges and double-flute design, which make them well suited for drilling in various materials. A hex shank adds even more versatility—these bits are compatible with standard drills and impact drivers. The kit includes five bits: 5/32 inch, 3/16 inch, 1/4 inch, 5/16 inch, and 3/8 inch.

Metal is a key component in countless construction projects. Aluminium and steel are the most prevalent, but copper, brass, and bronze are also commonly used.

In actual testing, we drilled through concrete, stone, and brick to see how well the drill bits fared. We used a standard DeWalt drill and a Milwaukee rotary hammer drill (depending on the individual drill bit shanks), and we drilled dozens of holes. We noted how well the bits performed and awarded points based on a rubric. After testing, we averaged the points to determine our best overall pick, and then we categorized the rest of the drill bits by their best usage.

For drilling jobs that require drilling through concrete or other stone surfaces, it’s important to use a drill bit that’s strong and sharp enough to bore through especially hard, dense material. Read on to learn about materials, bit type, drill compatibility, and other crucial factors to consider when choosing a masonry drill bit.

Spending money on specialty concrete bits that see infrequent use may not be the most economical way of expanding one’s collection of drill bits. This EZArc multipurpose bit set offers an excellent alternative. The bits’ design and carbide tips make them suitable for drilling through tile, concrete, and stone plus metal, wood, and even plastic.

This kit includes eight bits, ranging from 1/4 inch to 1/2 inch in diameter. The bits have SDS-plus shanks, so the user will need a rotary hammer drill to use them.

If you have additional questions about how to drill into concrete or choosing a drill bit for concrete or a drill bit for brick, you’ll find answers here.

Mark the intended hole location with a pen, then use a centre punch and hammer to create a small dip in the metal. This will help keep the tip of your drill bit in place as you start to drill.

Drilling into metal can cause tiny shards to fly off at high speeds. If one lodges itself in your eye, you’ll soon find yourself on an unpleasant trip to A&E. Make sure you’re wearing appropriate eye protection before you start drilling; safety glasses that wrap around the sides of your face are the best option.

Sharpening drill bits manually with a file or bench grinder is a complicated process. You need a machine specially designed for drill-bit sharpening to do it yourself. It’s usually easier to buy new drill bits.
