The oscillating multi-tool is one of the most versatile power equipment ever invented. Multi-tools derive their name from the fact that they oscillate rather than rotate or reciprocate, a mechanism that distinguishes them from reciprocating saws.
Oscillating multi-tools are also contrasted with manual multi-tools - the handheld, foldable implements designed with several blades and extensions for performing various tasks.
But like their handheld counterparts, oscillating power tools can serve numerous functions depending on the available attachments. Common applications include cutting through drywalls, making plunge cuts in decking, trimming screws and pipes, removing rust and grout, scraping adhesives, and sanding down paper.
Ever wondered what makes oscillating tool so versatile? Read on to find out.
Separate Blades for Different Tasks
The versatility of oscillating multi-tools is rooted in their ability to utilize different blade attachments. Multi-tool blades come in varied sizes and materials, each designed to perform specific assignments.
Below are common oscillating multi-tool blades, along with their corresponding applications;
1. Segmented Cutting Blades
Considered one of the most common oscillating multi-tool attachments, segmented cutting blades are distinguishable by their rounded, half-moon shapes.
Segmented blades have no offset teeth, allowing them to make clean cuts. They’re excellent for making linear cuts as well as creating plunge cuts. You can use the blades on different surfaces - metal, wood, or plastic - depending on their construction material.
2. Plunge Cut Blades
If the project entails making precise plunge cuts, you’ll have better luck using plunge-cut blades. These blades are also perfect for creating cutouts in drywalls and skirting boards.
As with segmented cutting blades, the surface on which you use plunge cut blades depends on their construction materials.
3. Scraping Blades
The oscillating multi-tool can function as an effective scraper if adequately deployed. With the right scraping blades, you can apply the equipment to remove old caulk, paint, wallpaper, or linoleum.
Multi-tools make light work of scraping jobs due to their automatic mechanism, saving you a great deal of time.
4. Sanding Pads
Smoothing rough edges is one of the essential functions of oscillating multi-tools. Simply attach a sanding pad to the blade, and you’re good to go.
However, note that multi-tools are primarily reliable in smoothing out smaller surfaces.
5. Bi-Metal Cutting Blades
Bi-metal (BIM) cutting blades are engineered for metal cutting applications thanks to their sharper and stronger designs. Consider these blades if planning to use an oscillating multi-tool to make precision cuts on metallic surfaces or to dislodge embedded nails.
Due to their enhanced robustness, BIM blades may also be useful in cutting softer materials like wood and plastic.
6. Diamond/Carbide Grit Blades
While BIM blades are tough enough to cut metal, they may not be so reliable when working with concrete. That’s where carbide or diamond grit blades come in.
Diamond blades are incredibly strong and durable, allowing them to slice through grout and tile with ease.
Corded and Cordless Varieties for Enhanced Flexibility
Another thing that makes oscillating multi-tools so versatile is that they’re available in corded and cordless varieties. Each option has its pros and cons.
According to many oscillating multi-tool buying guides, corded multi-tools provide the convenience of connecting these equipment to nearby mains outlets. They’re excellent when working on sites with uninterrupted access to electricity.
But if you’re looking for a blend of efficiency and flexibility, then cordless multi-tools will serve you better. These equipment are battery-driven, making them ideal for use in off-grid working sites.
Simply recharge the battery and power the equipment whenever required. You could also carry spare batteries to avoid downtimes caused when the operating battery runs out of charge.
Investing in a cordless oscillating multi-tool also minimizes shocks resulting from cable fraying or repeated cord plugging into receptacles. Besides, you won’t need to worry about tripping hazards caused by tangled cables.
The fact that cordless multi-tools are small and compact makes them all the more portable.
Fortunately, it’s exciting to note that modern oscillating multi-tool brands manufacture hybrid equipment, including a mains cord and battery ports. With such tools, you can readily connect to available mains outlets and switch to the battery during a power outage.
Caring For Oscillating Multi-tools
Considering the versatility of oscillating multi-tools, it’s intuitive to imagine that these equipment are challenging to maintain. Well, the converse is true.
Mindful usage is all it takes to properly care for and maintain your multi-tool.
First, avoid overworking your multi-tool. Allow ample time for the equipment’s motor to cool down, even if that means pausing the project.
Second, sharpen your multi-tool blades regularly.
Not only can using chipped blades endanger your safety, but it may also reduce your multi-tool efficiency and damage the equipment’s motors.
Experts also recommend lubricating your oscillating multi-tool regularly. Using certified lubricants, oil all moving components to reduce friction and wear.
Other common multi-tool maintenance procedures include;
- Tightening loose screws and bolts
- Recalibrating the equipment regularly
- Wiping dust off the tool after every use
- Replacing worn-out parts
- Minding voltage ratings when plugging corded multi-tools
Final Word
Oscillating multi-tools are a worthy investment for builders, woodworkers, and fabricators seeking an all-in-one power tool. From making cuts in drywalls to plunge-cutting decking to sanding down rough edges… multi-tools versatility is simply unparalleled.
However, like most power tools, the efficiency of oscillating multi-tools depends on proper application and maintenance.
Always use the right multi-tool attachments for each task. Remember to replace worn-out blades and grease-moving components and recalibrate the equipment frequently.
