Tungsten CarbideDrillBits

As previously mentioned, carbide drill bits have different types for your specific application. The twist bit is the most common drill bit type, which is perfect for many drilling projects. The name derives from the drill bit form, consisting of flutes along the drill bit body that helps transfer debris away from the hole. Secondly, the spade and hole saw bits work for larger-scale projects. The spade bit has bat-like wings with a sharp point in the center to keep the drill secure, while the hole saw has a hollow core that fills with drilled material.

Carbide drill bits consist of tungsten carbide, providing a high-heat dissipation rate, excellent strength, and maintaining a sharp edge longer than other drill bits. As a result, they’re perfect for drilling through rigid, hard materials, especially when performing demanding and challenging jobs. However, they aren’t necessary for at-home drilling projects, as carbide drill bits best suit more strenuous applications.

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.

Because carbide drill bits can work against harder materials, you can often see them in machine shops for production drilling and working in high-heat applications. When you’re purchasing carbide drill bits, think about the project and the type of carbide drill bit you’d need to best fit your project.

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 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.

Chip removal is when a piece becomes shaped using tools to remove excess materials. This helps obtain the degree of surface finish and dimensional accuracy, especially when working with complex shapes. One of the most prominent issues in drilling is chip removal. It’s especially apparent when processing low-carbon steel workpieces, as the issue is unavoidable, no matter which carbide drill bit piece you use.

Let’s discuss the considerations for purchasing carbide drill bits. Some things to consider are their benefits, various applications, and which works best for metal materials.

When your job requires proper industrial performance, you need the best-performing tools possible to get the job done efficiently and effectively. Furthermore, having the best drilling tools and accessories can help create accurate, smooth holes. When you’re buying carbide drill bits, there are many factors to consider, so you can improve your work productivity while reducing single-hole processing costs.

Adiseal Ultimate at an average of 31.7 seconds per hole, was over 4 times faster than the best cobalt metal drill bit from Bosch which took on average 132.4 seconds per hole.

For wear resistance testing purposes, the drilling was carried out without lubricants, coolants, or cutting oils, although these can help reduce the bit’s temperature and extend its lifespan. The drilling processes were video recorded and timed using video timestamps.

The hardest masonry drill bits are typically crafted from tungsten carbide, renowned for its extreme hardness and durability. Tungsten carbide surpasses the materials it drills into, like concrete, brick, and stone, making it ideal for prolonged use without premature wear or breakage.

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.

Adiseal Ultimate metal drill bits and masonry drill bits were found to be the best drill bits in our tests. They were found to be the most durable in our tests, drilling more holes than the competitor drill bits. They also drilled faster than any other drill bit in the drilling speed tests.

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.

Compared to other drill bit types, carbide drill bits stand out for many reasons. First, workers rely on them to drill holes into rigid materials, often by punching the material until it’s crushed by its repetitive up-and-down movement. The punched hole then transfers the excess debris of the material.

Carbide drill bits are powerful, effective drilling tools that outperform many drill bit types. They come in different construction based on your work materials, such as twist, spade, hole saw and step bits, along with varying drill bit sizes and widths for the perfect hole.
