Handheld grinders are versatile machines as they allow you to work in numerous areas and on different materials that otherwise wouldn’t be possible with larger planetary grinders. Given their usefulness in the construction field, it’s important that you understand how they work, what sort of blades are required, what sizes they come in and how to know when you’ll need replacements.
Here are all the answers you’ll need!
What Are Handheld Grinders?
Invented in 1954 in Germany, handheld grinders are handheld power tools used for grinding and abrasive cutting. They’re powered via an electric motor that drives a geared head, positioned at a right angle, which turns a disc at high speeds. This disk has a diamond blade attached to it which does the grinding.
Handheld grinders are used for areas that are particularly difficult to access. It could be that the floor of the room you wish to grind has a particularly tricky layout in one corner or that there’s a support structure in the middle of the space, around which it’s difficult to manoeuvre a larger machine. These scenarios are where handheld grinders are especially useful.
What Are Diamond Blades and How Are They Made?
Diamond blades are essential for the construction industry because of the durability of diamonds as a material, allowing for innovative applications like drilling and polishing. Diamond blades consist of a steel core along with diamond segments around the circumference of the disc. Synthetic diamond grit is combined with metal powder which is then sintered, meaning that these components are transformed into a solid coherent mass via heat and/or pressure.
What Sizes Are Available?
Diamond blades come in a range of sizes. Larger ones closer to 180mm are more suitable for stonemasons and flooring contractors. Alternatively, sizes closer to 100mm are better for detailed work and recesses. Here at Concept Flooring Technology, we stock 125mm and 180mm options so that we have all bases covered for our customers.
How Do I Know When My Diamond Blade is Dull?
You’ll know when the blade is getting dull because it’ll glaze over, indicating that the metal bond that holds the diamonds in place has melted over the diamonds. The blade will also appear to be smooth, showing that the diamonds have completely worn away.
How long they last is a difficult question to answer as it completely depends on the quality of the diamond blade as well as what type of material it’s used against. Generally, a 12 hour lifetime is considered ideal.
