How to choose the right magnetic drilling machine and cutter?

Choosing the right magnetic drilling machine is like picking the right pair of shoes for a journey. You wouldn’t wear hiking boots to a beach or flip-flops on a mountain trail. The terrain, distance, and weather all play a part in making the best choice. Similarly, the materials, conditions, and specific requirements of your drilling tasks determine which machine and cutter combination will take you further, faster, and with less wear and tear.

When it comes to selecting a magnetic drilling machine, it’s not just about finding the one with the maximum drilling capacity. Sure, if you’re often drilling 30 mm holes, it might seem logical to pick a machine that maxes out at 30 mm. But that’s not always the smartest or most efficient choice. Let’s dive into what you should really be looking for.


Focus on the job

It’s easy to get caught up in price comparisons, but when choosing a magnetic drill, it’s more important to focus on the specific drilling jobs you’ll be tackling. Are you drilling on the go, across multiple sites? If so, a battery-powered drill could be a game-changer. These drills save you the hassle of dealing with power sources and cables and losing a lot of setting up-time, allowing you to get to work quickly and getting more jobs done in less time. The time you save can make a battery-powered drill a highly efficient option.

 

Consider the material, depth, and conditions

If you’re drilling into thick materials, be mindful that some machines can overheat, which can reduce performance and shorten the machine’s lifespan. And if aluminium is a material you work with regularly, a magnetic drill might not be the best choice. The magnetic base simply won’t hold on aluminium. For occasional aluminium drilling, you can get by with alternative clamping systems to secure your drill. But if you find yourself working with aluminium often, a drilling machine with a vacuum base is your best bet.

Another important consideration is the depth of cut. If you need to drill deep holes, it’s crucial to choose a drill with a large stroke. The stroke length will determine how deep you can drill without having to reposition the machine, saving you time and effort. Another important factor to consider is the hardness of the material you’re drilling. Depending on that, a magnetic drilling machine with adjustable speed might help. Adjusting the speed correctly helps to extend the lifespan of your drill and ensures a cleaner, more efficient cut.

 

Mobility and space considerations

If you’re working in tight spaces or need to carry your magnetic drilling machine up ladders, consider the size and weight of the machine. A lighter, more compact mag drill might be a better choice if you need to maneuver in confined areas or transport the drill frequently.

 

Choose the right annular cutter: HSS vs. TCT

Just as important as choosing the right drilling machine is selecting the best annular cutter for the job. The type of cutter you use can significantly impact the quality and efficiency of your drilling.

High-Speed Steel (HSS) cutters are a popular choice due to their versatility and durability. They’re great for general-purpose drilling and can handle a variety of metals.  

On the other hand, Tungsten Carbide Tipped (TCT) cutters are designed for tougher jobs and are available in larger diameters. These cutters are harder and more wear-resistant than HSS, making them ideal for cutting through harder materials like stainless steel and cast iron. TCT cutters also allow for faster drilling with less heat buildup, which is crucial when working with thicker materials. Additionally, for larger drilling diameters, TCT cutters are often more affordable than their HSS counterparts, providing both cost savings and enhanced performance.

Also, think about whether you need to tap threads after drilling. Some magnetic drills come with tapping capabilities, which can be a big time-saver if you frequently need to execute both tasks.

 

However, it also depends on how many holes you’re drilling per day. If you are drilling just one 30 mm. hole per hour, an ECO.30 magnetic drilling machine will do just fine. But if you’re drilling all day long, you might want to consider a heavier machine for the job, for example the ECO.50+/T. It is portable, has a variable speed gearbox and has a tapping functionality. The right choice of machine can make a big difference in productivity and comfort.

 

The bottom line: choose efficiency

In the end, the key is to choose a drill and cutter combination that best suits the jobs you do regularly, rather than just going for the lowest price. Whether you’re deciding between corded and battery-powered drills, selecting the right tool for the materials you work with, or choosing between HSS and TCT cutters, always consider the specific conditions you’ll be facing. By doing this, you’ll strike the right balance between safety, efficiency, and durability, ultimately making your work easier and more productive. The right mag drill saves you time and money!
