When should I use a diamond core drill?

Within the masonry and construction industries, diamond drilling is a very popular drilling method that produces neat, accurate and precise results. There are very few materials that these state-of-the-art drills can’t get through, but it’s important to understand their limits before using your powerful accessory. With the right speed, pressure and lubrication, for instance, glass can be drilled into without any problems (breakages are rare if you use a good-quality diamond bit). Concrete can also be cracked or cut with these tools, as well as bedrock, which may be necessary if you’re installing pipework or foundations. Precision holes can also be created using small diamond drill bits, with either a solid, flat end, or tip.

In contrast, a diamond core drill shouldn’t be used on any metal or soft material, like soft wood. This can cause the diamonds to clog and eventually stop working efficiently. They should also never be used on tempered or toughened glass, as it will simply crack.

Things to consider before buying a diamond core drill

A large, robust and powerful tool, a diamond core drill is designed to drill concrete and other hard materials using a very wide bit (sometimes called a bell or a saw). They have a number of handy advantages, including reduced vibration (which helps to reduce fatigue), eliminated dust, quieter motors, and a higher level of precision, producing results that are accurate down to the last millimetre.

If you’re thinking of purchasing one of these convenient pieces of tech, it’s important that you first consider a range of factors, including frequency of use. For intensive use, or diameters greater than 182mm, choose a fixed core drill. If you’re frequently changing location, it might be worth opting for a portable or cordless model, which are available in a wide range of power outputs (encompassing both 110V and 240V models, depending on your needs). Next, think about location of use. Because water is impractical for most indoor work, it’s probably best to opt for a dry core drill if you’re working inside (to save you having to mop). Where water is not a concern, go for a water core drill instead, to help reduce wear and preserve the machine as much as possible.
