How to Cut Floorboards With Multi Tool? (5 Pro Tips!)

I’ve been in the flooring game for over 15 years, and I’ve seen it all.

One thing that always surprises me is how many people think cutting floorboards is some kind of mystical art reserved for pros with fancy, expensive tools.

They picture needing a massive miter saw or a specialized circular saw to get clean, precise cuts.

But let me tell you a secret: a multi-tool, that little workhorse often hiding in the corner of your toolbox, can be your best friend for cutting floorboards.

Seriously!

It’s versatile, easy to use, and can get into those tight spots where bigger saws just can’t reach.

So, ditch the misconception that you need to be a master carpenter to tackle flooring projects.

I’m going to share my top 5 pro tips for cutting floorboards with a multi-tool, and I promise, you’ll be amazed at what you can achieve.

Ready to dive in? Let’s do it!

1. Understanding the Multi-Tool: An Overview

Okay, so what is a multi-tool, exactly?

Think of it as the Swiss Army knife of power tools.

It’s a handheld tool that oscillates (vibrates back and forth rapidly) to power a variety of attachments.

You can sand, grind, polish, and, most importantly for us, cut!

The beauty of a multi-tool lies in its versatility.

You can swap out blades in seconds, making it perfect for tackling different materials and tasks.

Now, let’s talk blades.

There’s a whole world of multi-tool blades out there, and choosing the right one is crucial for cutting floorboards effectively.

You’ll find blades designed for wood, metal, plastic, and even grout removal.

For flooring, you’ll primarily be using blades designed for wood or multi-material cutting.

Here’s a quick rundown of some common blade types:

• Bi-Metal Blades: These are a great all-around option for cutting wood, plastic, and even some softer metals.
  
  They’re durable and offer a good balance of speed and precision.

• Carbide-Tipped Blades: These blades are the heavy hitters.
  
  They’re incredibly durable and can handle tough materials like hardwood, tile, and even nail-embedded wood.

  If you’re working with reclaimed wood or suspect there might be hidden nails, a carbide blade is your best bet.

• High-Speed Steel (HSS) Blades: These are generally used for cutting softer materials like plastic and thin metals.
  
  While not ideal for most floorboards, they can be useful for trim or other delicate tasks.

Why Choose a Multi-Tool Over Traditional Saws?

I get it, you might be thinking, “Why bother with a multi-tool when I could just use a circular saw?”

Well, here’s the deal:

• Precision: Multi-tools offer incredible precision, especially when making plunge cuts or working in tight spaces.

  You have much more control over the blade, allowing you to make intricate cuts without damaging surrounding materials.

• Ease of Use: Multi-tools are lightweight and easy to handle, making them ideal for DIYers of all skill levels.

  They’re also much less intimidating than larger saws, which can be a real confidence booster for beginners.

• Tight Spaces: This is where multi-tools really shine.
  
  They can easily reach into corners, under cabinets, and other awkward areas where a circular saw simply won’t fit.

• Less Dust: Compared to circular saws, multi-tools produce significantly less dust, making cleanup a breeze.

  Many models even have dust extraction attachments for even cleaner operation.

• Versatility: As the name suggests, multi-tools are incredibly versatile.
  
  You can use them for a wide range of tasks beyond cutting floorboards, making them a valuable addition to any DIYer’s toolkit.

For example, I was recently installing some laminate flooring in a small bathroom and needed to cut around a toilet flange.

A circular saw would have been overkill and nearly impossible to maneuver in such a confined space.

But with my trusty multi-tool and a fine-tooth blade, I was able to make a clean, precise cut in minutes, without any drama.

See? Multi-tools are awesome!

2. Pro Tip #1: Choosing the Right Blade for the Job

Alright, now that you know what a multi-tool is and why it’s so great, let’s talk about blades.

Choosing the right blade is absolutely crucial for getting clean, accurate cuts and avoiding frustration.

As I mentioned earlier, different blades are designed for different materials.

Here’s a more detailed breakdown of which blades to use for common types of floorboards:

• Hardwood: For solid hardwood or engineered hardwood, I recommend using a carbide-tipped blade.

  Hardwood is dense and can quickly dull other types of blades.
  
  Carbide blades are incredibly durable and can handle the abuse.

  Look for a blade with a fine tooth count (around 20-30 teeth per inch) for a smooth, clean cut.

• Laminate: Laminate flooring can be tricky because it has a hard, brittle surface that can chip easily.

  I’ve found that a bi-metal blade with a fine tooth count (around 24-32 teeth per inch) works best for laminate.

  The fine teeth help to prevent chipping and splintering.

  You can also use a specialized laminate blade, which has a unique tooth geometry designed to minimize tear-out.

• Vinyl (LVP/LVT): Vinyl flooring is relatively soft and easy to cut, but it can also be prone to melting or gumming up the blade if you’re not careful.

  A bi-metal blade with a medium tooth count (around 18-24 teeth per inch) is a good choice for vinyl.

  Make sure to use a slow, steady cutting speed to prevent the blade from overheating.

• Engineered Bamboo: Bamboo flooring is extremely durable and hard, similar to hardwood.

  A carbide-tipped blade with a fine tooth count is your best bet for achieving clean cuts without splintering.

Blade Material Matters!

The material of the blade itself also plays a significant role in its performance and longevity.

Here’s a quick comparison:

As you can see, carbide-tipped blades offer the best durability and heat resistance, making them ideal for tough materials like hardwood.

Bi-metal blades are a good all-around option for general use, while HSS blades are best reserved for softer materials.

How to Select a Blade:

When choosing a blade, consider the following factors:

• The Type of Flooring: As we discussed earlier, different flooring materials require different types of blades.

• The Thickness of the Flooring: Thicker flooring will require a blade with a longer cutting depth.

  Make sure the blade you choose is long enough to cut completely through the floorboard.

• The Nature of the Job: Are you making straight cuts, plunge cuts, or intricate curves?

  Different blade shapes and sizes are better suited for different tasks.

  For example, a narrow blade is ideal for making plunge cuts, while a wider blade is better for making straight cuts.

• Your Budget: Blade prices can vary significantly depending on the material and quality.

  While it’s tempting to go for the cheapest option, investing in a good-quality blade will save you time, frustration, and money in the long run.

I always keep a variety of blades on hand so I’m prepared for any flooring situation.

It’s like having a well-stocked toolbox – you never know when you’re going to need a specific tool!

3. Pro Tip #2: Preparing Your Workspace

Okay, you’ve got your multi-tool and your blade, now it’s time to prepare your workspace.

Trust me, a little preparation goes a long way in ensuring a safe, efficient, and enjoyable flooring project.

Clean and Organized:

First and foremost, make sure your workspace is clean and organized.

Clear away any clutter, debris, or obstacles that could get in your way.

A cluttered workspace is not only inefficient, but it’s also a safety hazard.

You don’t want to trip over a stray piece of wood or accidentally knock over a can of paint while you’re trying to make a precise cut.

Lay Out Your Floorboards:

Next, lay out the floorboards you need to cut.

This will give you a better sense of the overall project and help you avoid making mistakes.

Make sure you have enough space to maneuver the floorboards and the multi-tool.

Accurate Measurements:

Accurate measurements are absolutely essential for a successful flooring project.

Double-check your measurements before you start cutting to avoid costly errors.

I like to use a high-quality measuring tape and a sharp pencil for marking my cuts.

Secure the Floorboards:

Once you’ve laid out your floorboards and marked your cuts, it’s time to secure them.

This will prevent the floorboards from moving or shifting while you’re cutting, which can lead to inaccurate cuts and potentially dangerous situations.

I recommend using clamps or supports to hold the floorboards in place.

You can use a variety of clamps, such as C-clamps, bar clamps, or spring clamps.

Choose the type of clamp that works best for your specific project and the size of your floorboards.

If you don’t have clamps, you can also use scrap wood or other sturdy objects to support the floorboards.

Just make sure the supports are stable and won’t move while you’re cutting.

Pro Tip:

I often use a piece of foam board or cardboard underneath the floorboard I’m cutting.

This helps to protect the surface underneath from scratches and dents.

It also provides a slightly softer surface for the multi-tool blade to cut against, which can help to reduce chipping and splintering.

Preparing your workspace might seem like a minor detail, but it can make a huge difference in the overall quality and efficiency of your flooring project.

Trust me, taking the time to prepare properly will save you time, frustration, and potentially money in the long run.

4. Pro Tip #3: Mastering the Technique

Alright, you’ve got your multi-tool, your blade, and your workspace all set up.

Now it’s time to learn the proper technique for cutting floorboards.

Step-by-Step Guide:

1. Mark Your Cut Line: Use a sharp pencil and a straight edge to clearly mark the cut line on the floorboard.

   Double-check your measurements before you start cutting.

2. Position the Blade: Place the multi-tool blade on the cut line, making sure it’s aligned properly.

   The blade should be perpendicular to the floorboard for straight cuts.

3. Start the Cut: Turn on the multi-tool and slowly lower the blade onto the floorboard.

   Let the tool do the work – don’t force it.

4. Maintain Control: Keep a firm grip on the multi-tool and guide it along the cut line.

   Use a slow, steady cutting speed to prevent the blade from overheating and to minimize chipping and splintering.

5. Angle of the Cut: Maintain a consistent angle throughout the cut.

   If you’re cutting at an angle, make sure to keep the blade at the same angle from start to finish.

6. Starting and Finishing: When starting the cut, ease the blade into the material to avoid any sudden jerks or kicks.

   When finishing the cut, slow down and carefully guide the blade through the last bit of material.

   This will help to prevent splintering and ensure a clean, professional-looking cut.

Cutting Curves and Notches:

Multi-tools are also great for cutting curves and notches in floorboards.

To cut a curve, simply guide the multi-tool along the curved line, using a slow, steady cutting speed.

For notches, you can use a plunge cut to create the initial opening, then carefully cut along the sides of the notch.

Achieving Straight Cuts:

Getting perfectly straight cuts with a multi-tool can be a bit challenging, but it’s definitely achievable with practice.

Here are a few tips:

• Use a Guide: Use a straight edge or a clamp to guide the multi-tool along the cut line.

  This will help you maintain a straight line and prevent the blade from wandering.

• Take Your Time: Don’t rush the cut.

  Use a slow, steady cutting speed and focus on keeping the blade aligned with the cut line.

• Practice: The more you practice, the better you’ll become at making straight cuts with a multi-tool.

I remember when I first started using a multi-tool, my cuts were anything but straight.

But with practice and patience, I eventually learned to master the technique.

Now, I can make perfectly straight cuts with my eyes closed (well, almost!).

Pro Tip:

If you’re struggling to make straight cuts, try using a laser level or a chalk line to create a visual guide.

This can help you stay on track and ensure a straight, accurate cut.

Mastering the technique for cutting floorboards with a multi-tool takes practice, but it’s definitely worth the effort.

With the right technique, you can achieve professional-looking results without having to spend a fortune on expensive tools or hire a professional.

  Don’t try to multitask or rush the job.

• Keep a Clear Path: Make sure you have a clear path to move around your workspace without tripping or bumping into anything.

• Unplug the Tool: When changing blades or making adjustments, always unplug the multi-tool from the power outlet.

• Never Force the Tool: Let the tool do the work.
  
  Don’t force it or apply excessive pressure.

• Take Breaks: If you’re working on a large project, take frequent breaks to avoid fatigue.

  Fatigue can lead to mistakes and accidents.

In Case of an Accident:

Even if you take all the necessary precautions, accidents can still happen.

It’s important to be prepared for the unexpected.

• First Aid Kit: Keep a well-stocked first aid kit handy in case of minor injuries.

• Know Your Limits: Don’t attempt to do anything you’re not comfortable with.

  If you’re unsure about a particular task, seek help from a professional.

6. Pro Tip #5: Finishing Touches

You’ve successfully cut your floorboards with a multi-tool! Congratulations!

But the job’s not quite done yet.

Now it’s time to add those finishing touches that will elevate your project from good to great.

Smooth the Edges:

After cutting, the edges of the floorboards may be rough or splintered.

Use a sanding block or sandpaper to smooth the edges and remove any sharp points.

This will not only improve the appearance of the floorboards, but it will also make them safer to handle.

I typically use 120-grit sandpaper for initial smoothing, followed by 220-grit sandpaper for a finer finish.

Seal or Treat Cut Edges:

For hardwood floorboards, it’s important to seal or treat the cut edges to prevent moisture from penetrating the wood.

Moisture can cause the wood to warp, swell, or rot over time.

You can use a variety of sealants or treatments, such as polyurethane, varnish, or wood sealant.

Apply the sealant or treatment according to the manufacturer’s instructions.

For laminate or vinyl floorboards, sealing the edges is not usually necessary, but it can help to improve their water resistance.

Clean Up Your Workspace:

Once you’ve finished cutting and sanding, it’s time to clean up your workspace.

Sweep or vacuum up any dust, debris, or wood shavings.

Dispose of any waste materials properly.

A clean workspace is not only safer, but it’s also more enjoyable to work in.

Inspect Your Work:

Finally, take a step back and inspect your work.

Make sure the floorboards are properly aligned and that the cuts are clean and accurate.

If you notice any imperfections, now is the time to correct them.

Pro Tip:

For a truly professional finish, consider using a wood filler to fill any small gaps or imperfections in the cut edges.

Choose a wood filler that matches the color of the floorboards.

Apply the wood filler according to the manufacturer’s instructions, then sand it smooth once it’s dry.

Adding those finishing touches can make a huge difference in the overall appearance and durability of your flooring project.

Don’t skip this step!
