Defining the Spade Bit

A spade bit is a type of bit used for drilling holes.

A spade bit is composed of a long, narrow shank with two sharp cutting edges that angle outward from the tip.

The cutting edges are usually wider than the shank, and the tip is usually flat.

This unique design gives the spade bit the ability to cut through a variety of materials from wood to plastic.

Spade bits are typically used in woodworking, but can also be used in other applications.

They are versatile, and can be used for a wide range of tasks.

What Sets Spade Bits Apart


Spade bits can be an invaluable tool in any toolbox.

They are incredibly versatile, and can be used for a variety of tasks.

One of the biggest advantages to having a spade bit is its large size.

This allows it to be used for jobs that require a large bit like drilling out a plug hole in a wall, or drilling in a large hole for a cable.

Moreover, their shape gives you the ability to have a variety of cutting angles, so you can navigate around corners with ease.

Additionally, they are very long lasting, so you can get a lot of use out of them without having to replace the bit anytime soon.

Overall, the advantages of having a spade bit are numerous, making them a very useful tool.

How Spade Bits Work

Spade bits are a useful tool for drilling into wood.

They are made of hardened steel and typically have a sharp point and cutting edges.

When you use a spade bit, you insert it into a drill and apply pressure in order to start the drill.

As the drill rotates, the bit cuts into the material.

The pointed tip makes it easier to start the drill, while the cutting edges shape the hole, creating the perfect fit.

This also helps ensure neat, accurate holes every time.

Spade bits come in different sizes and shapes, allowing you to choose the best bit for the job.

Features to Look For

When shopping for a spade bit, it’s important to look for certain features.

Many spade bits come with a handle for easy gripping and two important removability systems, a quick-connect or a draw-bolt.

Both these features make it easy to switch between bits.

Look for bits with a precision-ground point, which gives a smoother, more accurate hole.

Another key feature to look for is ferrite magnets, which helps direct the bit and provide a smooth drilling experience.

Thick hardened cutting edges are essential for drilling smoothly and quickly.

Finally, don’t forget to check the spade bit’s length and width.

Long and wide bits like 3/8” or ¼” can provide a deeper and larger hole.

When to Use a Spade Bit

Common Applications

A spade bit is an incredibly versatile tool that can be used for many applications.

It is commonly used in wood-working, such as making furniture caseworks, drill holes, and mortising joints.

These bits are also great for drilling through soft metals, like aluminum, as well as materials like plastics or rubber.

Additionally, they can be used in sheet metal, where it is often used to create countersink holes for the mounting of screws.

This bit is also great for electrical work, in places when deep cuts needed to be drilled.

Whether you are working on projects around the house or in the workshop, this bit is an incredible tool to have in your arsenal.

Spade Bits In Your Workshop

Spade bits can be great to have in your home workshop.

They can help you tackle multiple tasks with ease.

Used for boring, countersinking and both enlarging and reaming existing holes, spade bits can save you time and effort on a variety of projects.

They are a great substitute for a forstner bit, dowel jig or even a standard drill bit.

You can also use a spade bit as a starting point for a hole saw or auger bit, making them a great addition to your toolbox.

With the right spade bit, you can make quick work of any project.

Techniques and Tips

When working with a spade bit, it’s important to keep in mind a few tips and techniques.

Make sure you have the correct size bit for the job, and use the bit exclusively at low speeds.

Apply light to moderate pressure for best results.

Additionally, make sure the rotation of the drill is the same direction of the cutting edge.

For best results, use a good quality lubricant, such as cutting oil, and occasionally straighten the bit with a sharpening stone.

For complex cuts, it might be a good idea to use a drill press or speed lathe.

Lastly, make sure to apply a light touch when starting the drill.

Following these tips and techniques will ensure a successful spade bit experience.

What To Look For In A Spade Bit

Spade Bit Options

When buying a spade bit, there are a few things to consider.

First, think about the use it will get - will you need a standard bit for everyday use or for a more specialized task? There are a variety of spade bits for different levels of work, from light duty to professional grade.

Second, check the length of the bit – the longer the bit, the deeper it will cut.

Finally, choose between the standard pointed design or the newer offset styles for faster, more precise drilling.

Techniques and tips, like variable speed control, are also helpful when using spade bits.

With these options in mind, you can find the spade bit that fits your needs.

Choosing the Right Spade Bit

When shopping for a spade bit, there are several things to consider.

The first is size.

Depending on the type of project you’re working on, you may need a large or small bit.

For larger projects, like cutting holes for electrical boxes, a larger bit is usually best.

For smaller projects, like drilling wooden dowel rods, look for a bit with a smaller diameter.

Another important factor to consider is the material the bit is made of.

High speed steel is the most popular option because it stays sharp for a long time.

However, there are also bits made of carbide or titanium, which last even longer but are more expensive.

The last factor to consider is the type of handle on the bit.

The handle should be secure and comfortable to hold, so look for spade bits with a simple shaped handle and with a textured grip.

This will ensure a safe and secure grip when operating the bit.

Brand Reliability

When choosing a spade bit, you should look for trusted and reliable brands.

Makita and Milwaukee make high-quality bits that are built to last.

They are known to have a sturdy construction and resist rust and corrosion.

Coarse and Fine Threaded bits by Bosch, Black & Decker, and Ridgid are also great options.

They are resilient and reliable, and they come at a reasonable price.

In addition, Rustoleum Zinc-Plated Bits are known for their corrosion and rust resistance.

For those on a budget, Apollo tools, Tax and Irwin offer spade bits that are cost-effective and highly-reliable.

Safety Measures and Precautions


Spade bits can sometimes get stuck in the wood.

If this happens, try rocking the drill slowly from side to side to get the bit out.

If the bit is stuck and won’t come out, don’t force it out.

Instead, loosen the bit with a wrench and then try rocking it again.

To avoid these problems, make sure to drill slowly and use a lubricant like beeswax to help reduce frictional resistance.

Lastly, make sure the bit is sharp and is the right size for the job.

If it’s not, you might have to struggle to get it into the wood.

Always replace dull or worn-out bits to avoid this issue.

Maintenance and Upkeep

Take extra care of your spade bit! Keep it clean and dry when not in use.

This will help prevent rusting and ensure that the bit is always ready to use.

When using the bit for an extended period of time, take periodic breaks to allow the bit to cool down.

If the bit becomes blunt, sharpen it to maintain its cutting efficiency.

Consider replacing the bit if it becomes too worn out.

Make sure to check for fractures in its blade and secure the bit’s handle before each use.

Follow the manufacturer’s instructions for maintenance since it will come with its own specific maintenance and precautionary rules.

Staying Safe

Always use safety glasses when working with a spade bit and any other power tools.

Always wear long sleeves and long pants to reduce risk of skin contact with potential debris.

Make sure the area around your work is clear and that there is good lighting to prevent slips or trips.

Keep a firm grip on the spade bit when turning the drill on and off, and always be aware of the bit’s position.

Remove cords out of the way to avoid tripping.

Put any extra tools away before turning on the drill.

Stop and inspect the bit for any damage before each use.

Be sure to inspect the work surface for any hazards or debris.

Do not overreach when using the bit.

Use safety guards and accessories if possible.

Disconnect the drill battery after each use.


Buying Your Spade Bit

It’s important to think about your needs before purchasing a spade bit.

Ask yourself questions like, “will this bit do what I need it to do?”, and “is this the right size and type for my project?“.

Make sure to factor in the cost vs.

quality - a more expensive bit doesn’t always mean a better one.

Be sure to read reviews of the spade bit you are interested in to make sure it’s reliable and able to do the job you need it to do.

Lastly, make sure to know the return policy of the store where you’re buying it, so that you won’t be stuck with a spade bit that doesn’t work for you.
