What Sets Keyhole Saws Apart


Keyhole saws have many advantages that make them extremely useful tools.

One of the primary benefits of having a keyhole saw is that it helps with precise cutting.

This type of saw has very thin blades that are adjustable.

It gives you complete control when you are making a cut.

Since the blades can be sharpened easily, you won’t have to worry about replacing the saw anytime soon.

The keyhole saw is versatile and can be used for cutting various materials with ease.

The handle is shaped so it fits perfectly in your hand and provides a solid grip when cutting.

All of these features make the keyhole saw an invaluable tool for any handy person.

How Keyhole Saws Work

Keyhole saws are special, hand-held saws with a thin, sharp blade.

They consist of a handle and an angled blade that can cut thin grooves with precision and accuracy.

The blade has a series of small, sharp teeth that make repeated cuts along the surface of the material you’re cutting.

This helps the saw produce a smooth groove without splintering or cutting too deeply.

Keyhole saws are unique in that they produce a very narrow cut without risking damage to the surrounding material.

This makes keyhole saws perfect for cutting small, intricate shapes and designs.

Features to Look For

A keyhole saw should offer features like a narrow width and high-quality teeth.

Look for one that has a blade that’s no more than 2 inches wide so you can make precise cuts.

Make sure the teeth are sharp and strong for better cutting performance.

If your saw does not have an adjustable blade, consider buying one.

An adjustable blade allows you to make cuts of various depths as needed.

Look for saws with different handle options – plastic or metal – for better gripping power and control.

Lastly, buy a saw that has a secure lock-in system and a dust shield to protect you from chips and debris.

When to Use a Keyhole Saw

Common Applications

A keyhole saw is a versatile tool that is great for many different applications.

It is often used for cutting small, precise notches, circles, and circles, which makes it a great choice when needing to install door locks, door handles, and window hardware.

The smaller size of the blade allows it to make precise and intricate cuts, making it great for detailed and professional carpentry projects.

It can also be used to make holes in drywall for cords.

Keyhole saws are often used for making shallow cuts in the free edge of hardwoods.

They are also good for remodeling projects, such as making cuts in basements and attics.

Keyhole Saws In Your Workshop

Keyhole saws are a helpful tool to have in your home workshop.

They can be used to make holes in wood and to even cut through metal and plastic.

They come in handy when you need to make neat, precise cuts without having to use larger saws.

With a keyhole saw, you can easily make curved or angled cuts instead of straight line ones.

You can even use it to make tight, intricate patterns.

Keyhole saws can be used as an alternative to drill bits, allowing you to make larger or deeper holes.

They can also be used in conjunction with other tools, such as a combination blade saw and a jigsaw, in order to make more technical cuts.

Techniques and Tips

When using a keyhole saw, it is important to use the right techniques for the job.

Make sure you choose a blade that is the correct size for the material you are cutting.

When cutting, go slow and take your time.

Don’t put too much pressure on the saw or it may break.

It’s also important to keep both hands on the saw while sawing.

For harder materials, you can use a back and forth, or reciprocating motion to get the job done.

When using a keyhole saw in tight spaces, be aware of your surroundings and do not cut near any items that could be damaged.

Take extra precautions when using a keyhole saw near flammable materials.

What To Look For In A Keyhole Saw

Keyhole Saw Options

Using a keyhole saw can require different techniques and tips depending on the saw you have.

For example, a pull saw works best for straight cuts and should be pulled back toward you.

While using a coping saw, it is important to allow for more space between the frame and the blade, allowing for a clean, smooth, and precise cut.

With a fretsaw, a sawing motion is used that helps ensure a precise cut with minimal tearing.

Finally, when using a jigsaw, be sure your blade is perpendicular to the cutline on either side for the best results.

Choosing the Right Keyhole Saw

When it comes to choosing the right keyhole saw, there are several things to consider.

Firstly, you should think about the size you need.

This will depend on the job you’re doing.

If you need a keyhole saw for a large project, you’ll want to look for one that is longer and has more teeth.

Secondly, look at the blade or cutting edge.

You’ll want to choose a keyhole saw that is strong and durable so you can get the job done.

Thirdly, check out the handle.

It needs to be comfortable and easy to use.

Lastly, know your budget.

Keyhole saws come in different price ranges so it’s important to shop around and find the right one for you.

Brand Reliability

When buying a keyhole saw, it’s important to look for brands known for their reliability and durability.

DEWALT and Bosch are both well established tool brands with excellent customer reviews.

Makita is another brand to consider since their tools are popular among professional contractors.

Their saws include advanced features and ergonomic designs.

A high-end option worth considering is the Festool range – a German brand renowned for its precision tools.

With any of these reliable brands, you can be sure that you’re making an informed decision and getting a long-lasting keyhole saw.

Safety Measures and Precautions


Keyhole saws occasionally can become clogged with material from the object being cut.

If you feel the blade is stuck, turn off the saw and wait for it to cool down before attempting to unclog the blade.

If needed, use a small tool to carefully remove the clogged up material.

Sometimes the blade might become loose over time.

Check all screws, nuts, and bolts to make sure they are properly tightened.

Always use a wrench to do this and be sure to wear gloves and safety goggles when making adjustments.

Additionally, inspect your saw blades often for any warping, chipping, or other signs of wear or damage.

If you come across any, it may be time to replace the blade.

Maintenance and Upkeep

Regular maintenance is key to ensuring your keyhole saw stays in top condition.

Make sure to clean it after each use, removing any debris or buildup.

Lubricate the blade with oil to ensure it stays sharp and prevent rusting.

Check it for any signs of wear and tear, and replace parts if necessary.

Before each use, ensure the blade is securely tightened and that the adjustment levers are correctly set.

Be sure to store the saw in a safe and dry place to extend its lifetime.

In addition, have the saw professionally serviced once a year for optimal performance.

Following these simple steps can help you get the job done right, safely and efficiently.

Staying Safe

When using a keyhole saw, it is important to stay safe.

Wear appropriate safety glasses and clothing while handling and sawing.

Secure the wood that you are sawing with clamps to hold it in place, and never saw toward yourself.

Make sure you have a strong and secure grip on the saw, and always work in a well-lit area.

Disconnect the saw from any electrical power source before making adjustments.

Always inspect the saw before and after every use.

Check for any cracks, cracks in the insulation or loose or broken wires before using.

Immediately remove any sawdust or other debris from the saw to keep it in top condition.


Buying Your Keyhole Saw

Buying a keyhole saw should be a careful process.

Think about budget, what types of projects you plan to use your saw for, and the type of material you plan to cut.

You also should think about the size and shape of your keyhole saw.

Make sure it meets the needs of your project.

If you need to cut curved shapes or tight angles, you might need an angled keyhole saw.

Also research more about construction grade of your keyhole saw.

Look into how the saw is powered (electric or manual) and whether it’s adjustable.
