Whether you’re sanding, cutting, grinding, or scraping, an oscillating multi tool can save you a ton of time thanks to its multi-use functionality. The choice of attachments reduces the need for carrying around many other tools, which can streamline your work and help you to complete jobs much faster.
Types of Oscillating Multi Tools
Oscillating multi tools are available in two different types; corded and cordless. Which one you choose will depend on a number of factors such as the jobs you wish to complete and whether or not you’d prefer an on-demand power supply.
Corded Oscillating Multi Tool
A corded oscillating multi tool is powered by a mains supply. So, wherever you’re working, you’ll need to be in close proximity to a plug socket or extension lead. The consistent power supply makes them ideal for DIY projects that take a little longer, such as removing wallpaper. This is because they won’t run flat midway through a job.
As you don’t need to worry about the power diminishing while you work, they’re also great for heavy duty jobs like plunge cutting and routing. That said, the need for electricity does mean they won’t suit all environments, especially where a power supply could pose a health and safety risk.
Keep in mind that they lack the same portability and manoeuvrability as cordless models so if you’re looking for something that’s best suited for jobs away from home, a corded tool could be a better option.
Advantages
-
Consistent power
-
Good for heavy duty or long duration tasks
-
More durable compared to cordless models
Things to Consider
-
Need to be close to power supply
-
Lack portability & manoeuvrability
Cordless Oscillating Multi Tool
A cordless oscillating multi tool is powered by a battery, usually lithium-ion. Compared to corded multi tools which have an in-built motor, the great thing about li-ion batteries is that they’re lightweight making them easy to handle. The lighter weight and lack of a power cord increases their versatility as they’re easy to manoeuvre and navigate into awkward spaces.
While cordless models are great for intricate projects that require a little more precision, they’re not always suitable for heavy-duty work simply because they lack the same power output. A key consideration of cordless options is that to power them you need to apply constant pressure which may cause fatigue to hands and fingers.
You can expect to pay a little more for a cordless multi tool due to the type of battery housed within. Compared to corded tools, they also carry additional and ongoing costs due to the expense of purchasing new batteries.
Advantages
-
Lightweight making them easy to handle
-
More versatile as no power supply needed
Things to Consider
-
Can be more expensive to purchase
-
Not as powerful
-
Additional expense of replacement battery
The Different Multi Tool Attachments & What They Do
Segment Blade
A segment blade is a type of cutting blade which has a half moon or ‘C’ shape. They can be used on various materials ranging from wood, metal and plastic. Their shape makes them perfect for making long and neat cuts.
Sanding Plate
Sanding plates are usually triangular or circular in shape. To use them you’d attach a single-use sanding sheet which can then smooth out or shape surfaces like wood. Sanding pads come in a variety of different grits which determine how abrasive they are.
Scraper Blade
A scraper blade is used for scraping materials like wallpaper, paint, mastic, and sealant. Compared to a manual scraper, it’s much quicker, saving you lots of time. They typically come in different shapes and sizes with some suited for large surface areas and others best for smaller spaces and hard-to-reach areas.
Plunge Cut Blade
A plunge cut blade is a straight edge blade designed for making deep plunge cuts in thick material such as wood. They allow for clean and precise cutting while offering a safer alternative when compared to using a circular saw. A key benefit of plunge cut blades is that you can begin cutting anywhere in the material as opposed to at the end.
Different Oscillating Blade Materials
Bi-Metal
A bi-metal blade is manufactured using two different types of metal which contributes to its heat resistance, flexibility, and strength. They can be used on a wide variety of materials but are more commonly used on different metals thanks to their durability. The flexibility of bi-metal blades increases their lifespan when compared to HSS blades and for that reason you can expect to pay a little more for them.
Carbide Grit
Carbide grit blades are notable by their textured edging which is formed by carbide fragments which are fused along the edge of the blade. This makes them incredibly tough and perfect for working on harder materials or if undertaking a large volume of work. The hardness of each blade means they last longer while maintaining their shape. It’s worth noting that they tend to be more brittle compared to other blade types.
Diamond Grit
Diamond grit blades have a similar appearance to carbide grit but feature diamond particles along its edging. Compared to carbide, they’re incredibly resistant to wear meaning they stay sharper for longer. The quality of the finish when using a diamond grit blade is far superior compared to other material types but they can cost more.
High Speed Steel
High speed blades, often abbreviated to HSS blades, are hardened to increase their durability. Popular for use on materials like wood and softer metals, they tend to carry a lower price tag compared to other blade types. Due to their lack of flexibility, they often wear faster, especially when used on harder materials.
Things to Consider Before Buying An Oscillating Multi Tool
Brushed VS Brushless Motor
Oscillating tools that feature a brushless motor are usually smaller in size and have a much longer lifespan which contributes to their higher cost. They tend to be easier to look after as no brushes means less maintenance. However, if you want a simpler tool that's a more purse-friendly option, a brushed motor could be a better option.
Weight
A cordless multi tool is usually heavier due to the inbuilt battery. While they’re more portable, this heavier weightload can make them cumbersome to handle, especially when working on long duration jobs. In contrast, even though corded tools are lightweight they’re constrained by the need of a power supply.
Specific DIY Tasks
Before investing in a multi-tool, consider the type of jobs you’ll want to be able to undertake. Keep in mind that some oscillatory tools only allow for cutting work and not things like sanding or scraping. So, if you want a multi-purpose all-rounder, check the types of blades that are compatible with it before buying.
Power Output
OPM stands for oscillations per minute and this indicates how many times the blade moves from side-to-side, or oscillates, within 60 seconds. A tool with a higher OPM is more powerful making it best suited to harder materials like metal. On the other hand, a tool with lower OPM is great for things like wood and plastic and can be ideal for work that requires a little more precision.
