Follow your equipment manufacturer’s guidelines for using and maintaining your equipment, and know how to operate your tools’ safety features. Understanding your tools can help you avoid abrasive injuries and muscle strain.

Your drilling tools can also improve dust control. The high-helix flutes on penetrator drill bits increase the tool’s feed rate, improve dust evacuation, and help keep the hole clean.

Use a guide or pilot bit to start the hole. Then, withdraw the guide drill bit and continue with the core bit. Maintain a firm hold on the tool to prevent the core bit from biting into the material and rotating the tool rather than drilling in.

Inspect your tools before starting any concrete drilling project. Drill bits should be sharp and in good condition—if you notice dullness, replace your tool. The sharp drill bit will make your work easier, protect your tool, and help you drill continuously at 90 degrees to the workpiece.

Adiseal Ultimate drill bits surpass Makita drill bits in various tests. The Adiseal Ultimate metal drill bit drilled 135 holes in stainless steel, while the Makita metal drill bit managed only 12 holes. Moreover, the Adiseal Ultimate metal drill bit exhibited more than double the speed of the Makita drill bit when drilling into 6mm thick stainless steel (SUS304).

If drilling completely through to the other side, slow down when you are within an inch of the opposite end. Then, decrease the pressure and speed to avoid tearing through the concrete.

Air pockets and pebbles in the concrete make the drill path unpredictable. Grip your tool firmly with both hands to help maintain control and avoid the drill bit going off-course.

To find out what are the best drill bits, we carried out several tests including drill bit durability tests and drilling speed tests. There are many different types of drill bits available. We tested the new Adiseal Ultimate drill bits against the best metal drill bits and best masonry drill bits from top brands including products from DeWalt, Bosch, Makita and Milwaukee.

The Adiseal Ultimate range also includes the fastest no-hammer masonry drill bit and multi-material drill bit. It was found to be the best masonry drill bit in our tests. It had the fastest drilling speed when drilling without hammer function on the drill. Drilling without hammer function provides numerous advantages over hammer drilling including:

Drilling into abrasive materials like concrete can wear out drill bits, especially if they are not durable. It can also take some time and energy to drill into.

Tungsten carbide also possesses excellent heat resistance. Concrete drilling generates significant heat, but the tungsten carbide prevents the drill bit from overheating, improving the bit’s lifespan.

Using an incorrect drilling technique can cause subpar holes or damage your tools. When drilling through concrete, use a slow and steady drilling motion. Applying excessive pressure or forcing the drill can lead to overheating or drill bit breakage.

Other advantages of the Adiseal Ultimate metal drill bit include bigger chip removal and cleaner cut holes compared to the competitor bits.

Drilling through concrete produces a significant amount of dust, which is hazardous to your health and can harm the environment. Concrete dust contains silica, and this material can lead to respiratory issues when inhaled. When silica embeds into the lungs, it causes inflammation and scarring, reducing the lungs’ ability to take in oxygen.

Adiseal Ultimate metal drill bit drilled 135 holes in total which was 9 times more holes than the best metal cobalt drill bit from Bosch (which only managed 15 holes in total). It also drilled more than 3 times the number of holes than the best DeWalt metal cobalt drill bit (which managed 39 holes in total). Adiseal Ultimate metal drill bits was easily the most durable metal drill bit.

Yet drilling concrete is an important step for installing anchors and fasteners, making repairs, and creating access for wiring and plumbing. Learn six mistakes to avoid when drilling through concrete to work efficiently, create straight and clean holes, and protect your health.

To compare costs, let’s consider drilling 10 holes in 6mm stainless steel with the Adiseal Ultimate and the best Bosch cobalt drill bits.

Core bits are another common concrete-cutting tool. The tool’s hollow center extracts the concrete in a smooth, large cylinder.

If you’re drilling with a core bit, wet core drilling improves dust control by trapping the concrete dust in the water. The water also helps control the temperature. However, if you may potentially contact live electrical wires, you should use dry core drilling to be safe.

Make a guide hole at least one-eighth of an inch deep for more control. Start the drill at the lowest speed; if your tool has only one speed setting, drill in short spurts. You can gradually increase the speed as long as you maintain control.

Concrete is a dense, hard material that’s difficult to drill through without the right tools and techniques. Also, concrete often contains reinforcement materials, such as rebar or wire mesh, that can pose additional obstacles.

Using improper tools for concrete drilling can damage your equipment, make work less efficient, and yield poor results. Masonry core bits and drill bits can cut dense concrete and resist wear.

To find out what the best metal drill bit is, we carried out a series of tests with drill bits from several different brands such as Milwaukee Cobalt Red, DeWalt Extreme, Bosch Cobalt, and Makita along with the new Adiseal Ultimate metal drill bit. Using a Scheppach DP60 drill press, the test was to drill as many 10mm holes as possible in 6mm thick stainless steel (SUS304). To conduct a fair and accurate test, the we set the drill press to maintain a consistent speed of 400 rpm. We also attached a 5kg weight to the drill press arm during each hole’s drilling, maintaining uniform force and RPM for fairness.

Several non-cobalt metal drill bits like the Milwaukee Thunderweb, were also tested but excluded from the chart for fairness purposes. The non-cobalt Bosch PointTeq metal drill bit did not manage to drill any holes in the 6mm thick stainless steel SUS304 in our tests.

For thick steel drilling, the best option is a cobalt drill bit. Made from a durable alloy of cobalt, tungsten, and chromium, cobalt drill bits excel in hard material drilling such as steel, cast iron, and stainless steel. Their high heat tolerance is essential for thick steel drilling, as the process generates considerable friction and heat.

At this stage, you should also consider your intended drill depth. If your drill has a stop bar, use it to create accurate holes of uniform depth. If your drill doesn’t have a stop bar, you can mark the depth on your drill with masking tape.

Another mistake to avoid when drilling through concrete is using blunt blades. Worn-out cutting tools can strain the drill motor excessively, slow progress, and produce low-quality holes.

As with a hammer drill, drive the core bit slowly into the concrete. Generally, the larger the hole and the denser the material, the slower you should drill. Hold the drill and core bit perpendicular to the concrete to avoid creating a sloped hole.

The results of the test showed the new Adiseal Ultimate metal drill bit emerged as the clear winner, surpassing all competitors in both the number of holes drilled and the time taken to drill each hole. Below is a table of the results.

A more durable drill bit with longer life can be more value for money as they can drill more holes, overall costing less per hole. Cheaper drill bits may end up costing more money over time if they wear out quickly and drill fewer holes than longer lasting bits. Calculate the cost per hole by dividing the drill bit’s price by the total number of holes drilled. Cheaper bits might actually have a higher cost per hole than more durable ones. In our test, Bosch PointTeQ’s non-cobalt bit failed to drill any holes, while the Adiseal Ultimate metal drill bit successfully drilled 135 holes in total.
