When it comes to projects that work with various materials and many different applications, it can be difficult to get the job done quickly and precisely. These types of projects require using multiple tools, which can use a lot of time and effort, as well as create chaos with tools all over the place. Professionals can frantically try and find a different tool for a certain job and then be back to looking for yet another tool, which can create an unorganised mess of tools and make it hard to find what they need for each task. This takes up precious time to complete the project and slows everything down, while also causing wear and tear to many different tools. To prevent this, the multi-tool was created to tackle various applications and materials with just one tool.
The multi-tool is a heavily relied on tool for many professionals in all types of sectors because it’s compact, extremely tough and covers a range of tasks that usually need several individual tools. Whether it’s trimming wood, cutting pipe, scraping grout or sanding tight corners, it saves time and hassle every day. Builders, plumbers, electricians and joiners all keep one close because it handles the awkward jobs that other tools can’t reach. This tool uses different blades for each material or application, which means that the blades are a very important part of the tool. If you pick the wrong one, you’ll end up with dull edges, slower cuts or even surface damage. Due to this, we’ve created this guide to help you choose the right blade and use a multi-tool correctly. From how long do multi-tool blades last to are multi-tool blades universal, you can learn about these adaptable and essential tools to help with your project.
Are Multi-Tool Blades Universal?
The first thing you need to know before buying a multi-tool is the answer to the popular question of, “Are multi-tool blades universal?”. Multi-tool blades aren’t completely universal, it depends on which ones you have or are thinking of buying. Generally there are 2 types, Starlock fitting and Non starlock fitting. All our blades will fit any Non Starlock multitool
The next question usually follows of “Are all multi-tool blades interchangeable?” Again, not exactly. If your tool has a Starlock mount, you’ll need Starlock Blades. for any other type of fitting then our multi tool blades will fit. Due to this, it’s always worth checking the manual or packaging before buying a mixed blade pack that might not fit.
If you’re wondering, “Are multi-tool blades interchangeable between brands?”, it depends on the fitting system. Bosch and Fein developed Starlock together, so their Starlock blades will work with any Starlock multitool.
Sharpening, Changing, and Blade Lifespan
Using high-quality blades makes all the difference to the finish of your project, no matter what applications you’re carrying out. If you use a blade that is dull or worn, you can experience a much slower cut that puts your project behind. As well as this, the blade can easily overheat the motor of the multi-tool, causing it to become damaged or even broken.
Because you can’t use a dull blade, it’s normal to wonder if you can sharpen multi-tool blades. Sharpening blades all depends on what sort you’re using, as some can be sharpened and others can’t and will have to be replaced with a new blade. If you’re using bi-metal or high-speed steel blades, these can both be sharpened a little with a file or stone. However, doing this won’t make them brand-new again, but it can make them better at handling softer materials. If you’re relying on carbide or diamond grit blades, these can’t be sharpened. This means that once their surface starts to wear, the blade’s lifespan is over, and a new one needs to replace it. To get a longer lifespan out of these types of blades, it’s best to regularly clean them and let them cool down during use.
As for how long do multi-tool blades last, that depends entirely on what they’re cutting. For using them on softer materials, such as wood and plastic, your multi-tool blades can be expected to last for a long time. However, if you’re regularly using it for heavy-duty, tough materials, then expect them to wear down faster. On top of this, if you force the blade during your project, you’ll be shortening its life. It’s essential to let the oscillation do most of the work and take things slow and steady with gentle pressure to make the blade last longer.
When it comes to how to change a blade on a multi-tool, most modern versions make it simple. Unplug or switch it off, open the latch, swap the blade, then lock it back in. Starlock systems snap in and out in seconds, no tools needed, making it one of the handiest upgrades ever made.
Top 10 Uses for Multi-Tools
Removing Grout
Anyone who’s tried scraping grout by hand knows how tiring and time-consuming it is. Multi-tools make this challenging job much easier and quicker, so that you can focus on the more important parts of your project. They shine at removing grout, especially when fitted with a diamond or carbide grit blade. These blades grind the grout away quickly and precisely, helping to speed up your project and create a flawless finish. A multi-tool is a fast and clean way to remove grout without the risk of damaging the surrounding tiles, keeping everything pristine and intact.
When using a multi-tool for removing grout, it’s best to tape around the grout lines before starting, especially when working on ceramic tiles. This is because they can chip easily, so it’s ideal to begin slowly to make a shallow groove. Once you’ve done this, increase the speed at a steady pace. Make sure you always wear goggles and a mask as grout dust goes everywhere.
Cutting Wood
A multi-tool is also great for cutting all sorts of wood precisely for a clean, stunning finish. You can use it to trim door frames, fit skirting or even cut out sections of flooring. This tool works with wood easily and flawlessly more than any other tool. It can reach every area of the material where a circular saw can’t reach!
Using a bi-metal blade is best for general cuts in wood. However, if you need to carry out intricately detailed woodwork, using a fine-tooth blade is the best for cleaner, more precise results. Once you’ve finished the cut, use a sanding pad to finish the edge right away for a smooth, chip-free finish.
Tile Removal
Trying to pry off tiles using hand tools is a huge challenge that takes up a massive amount of time. You can make this much quicker and easier by using a multi-tool with a scraper or pry blade. This can remove tile in an instant with minimal effort and a whole lot less time spent, helping you to focus on what truly matters. The blade easily slides under the tile and loosens the adhesive with ease.
Make sure to keep the blade flat and work in sections at a time for a precise removal. The key to a successful tile removal with a multi-tool is to go slow for a smaller vibration. This means there will be fewer cracked edges and an overall cleaner lift.
Trimming Doors and Skirting
Multi-tools are perfect for trimming doors and skirting neatly and quickly. If flooring has lifted a door just enough to scrape against it, then this tool can easily solve the problem. Using a flush-cut blade with the tool can instantly trim the bottom edge of the door and create a smooth, clean finish that doesn’t scrape the floor. It also helps undercut door frames or skirting when laying new flooring.
Because of its narrow head, it fits into tight corners easily. The precision here is hard to match with a saw, and cleanup only takes a matter minutes.
Cutting Brick and Masonry
Electricians and plumbers often need narrow channels for cables or pipes. They often work with hard-to-reach areas and tough materials, such as brick and masonry, and traditional hand tools can struggle to get to these areas, making a project slower. A multi-tool can be the answer to this problem, especially when using a diamond grit blade on it. This can reach the difficult areas and can carry out intricate jobs precisely to easily deal with narrow channels.
A multi-tool for cutting brick and masonry may not be as quick at the job as an angle grinder. However, it’s safer, cleaner and gives much better depth control. For shallow chases or fine shaping, it’s ideal because there’s less dust, less vibration and more control.
Cutting Concrete
Working with concrete can sound like too much for a multi-tool to handle due to it being quite small. However, this is not the case. If you use the right blade with this tool, then it can easily withstand the hard exterior of concrete. Choose a diamond or carbide blade to work with concrete accurately. These blades can handle smaller grooves and intricate details, giving a smooth, clean cut through this tough material.
When working with concrete, make sure to gently mark the line before applying more pressure. Having patience matters because each surface and type of concrete you’re working with reacts differently. You should also go slowly when using a multi-tool for this material because it’ll give you a cleaner, flawless finish with no cracks or burn marks.
Cutting Metal
Multi-tools cut metal better than most people expect. With a bi-metal or carbide-tipped blade, they slice through bolts, nails or sheet metal smoothly and accurately. They can make working with all sorts of metal easy and help you create fine details perfectly. This is because the oscillation a multi-tool provides reduces kickback, keeping it safe and steady.
Make sure to use light pressure and a steady motion to prevent the multi-tool from overheating. When done right, the cut edges stay clean and ready for finishing or welding.
Furniture Restoration
For furniture repair or restoration, a multi-tool is invaluable. It sands, trims and smooths detailed sections where bigger sanders won’t reach.
Using fine-grit sanding pads with the tool helps it handle corners and curved edges perfectly. It’s also great for removing varnish or cutting out small damaged spots before refinishing. The control it offers makes delicate restoration easier and more precise.
Rust Removal
By attaching a wire brush to the tool, you turn your multi-tool into a great rust remover. When you do this, you can use your multi-tool to clean metal gates, pipes or fittings quickly without cutting into the material underneath.
Using your multi-tool for this application should be done with light pressure. If you push too hard, then you can bend the bristles and wear them down really fast. It’s also best to keep on changing the direction halfway through to maintain an even finish. Once done, apply rust treatment to seal the surface.
Stripping Paint
Old paint layers can be stubborn. A scraper or sanding pad on a multi-tool peels them off with minimal effort. It leaves the surface smooth and ready for primer.
Keep the speed moderate to avoid overheating and dust. For large surfaces, move in slow overlapping passes. Always wear a mask if there’s old paint involved to keep yourself safe at all times.
