Spade Bit Vs. Auger Bit Vs. Forstner Vs. Hole Saw Vs. Carbide Burrs [Explained]

New woodworkers may not know the difference between a spade bit, Forstner bit, Auger bit, Carbide burrs, and hole saw.

You might wonder,” Which one is the best among Spade Bit Vs. Auger Bit Vs. Forstner Vs. Hole Saw Vs. Carbide Burrs?

If you want a quick, messy cut, Use the spade bit. Otherwise, Auger bits are ideal for a clean cut. A hole saw is ideal for a smooth full hole. If you want a smooth, but rushing finish, the Forstner bit is best. Finally, a carbide burr set is handy. This is a great tool for adding detail to the wood.

That was for the summary. I have made this article just to help you figure out which one is ideal for you.

Let’s hop in.

Spade Bit Vs. Auger Bit Vs. Forstner Vs. Hole Saw Vs. Carbide Burrs: Quick Comparison

You might be wondering which kind of drill bit would be best for the work that you need to do.

It is possible for you to convince yourself, psychologically speaking, that spade bits are superior.

However, that might not be the case in this particular scenario. Things may vary from situation to situation.

What’s the best spade bit, Forstner bit, hole saw, auger bit, or carbide burr?

There are a lot of things to think about before I can answer it.

You need to consider the Cleanliness of Cut, Speed, Hole Size & Depth, Angled Drilling & Price. Then you can come to a decision on choosing the right one for your purpose.

Now that we have sorted it out. Let’s take a quick look ahead and determine which aspects were the most crucial.

This short review gives away a lot of information. But you need to understand more about each one. If not, it might be hard to choose the right drill bit.

But don’t be afraid. Because in the next section, I’ll compare the drill bits in detail.

Let’s keep going.

In-Depth Comparisons

If you’re new to woodworking, you might not always know when drill bits are best.

Each of these tools is used to drill holes in wood. But they can make holes that are different in shape, size, and how smooth they are.

However, the burrs are used for something else by people who work with wood.

After getting a high-level understanding, the process becomes simple. You will know exactly when and why to employ them.

For this, I have prepared an in-depth comparison for your convenience.

Cleanliness of Cut

The correct tool for the job can be determined by the intended purpose of the cut.

The spade bit is capable of creating both through holes and holes with flat bottoms. However, it’s important to keep in mind that the borders of these holes are frequently a bit rough.

This is not an issue with auger bits. Using this tool, you may remove any dirt or dust from the surface and get a smooth, polished end result.

The other two options are tidier, so consider them if you value cleanliness.

Only flat-bottomed holes can be drilled using a Forstner bit set. Compared to holes made with a spade bit, these are far more precise.

Carbide burrs aren’t designed to make holes, as I’ve already mentioned. They work wonderfully for carving intricate designs into wood, rounding off rough edges, and adding finishing touches.

Finally, if you need a hole that goes all the way through, the hole saw is your best bet. These cuts are as clean and exact as a Forstner.

Speed (rpm)

These instruments also come in a variety of speeds. Time is of the essence when working with wood. But you shouldn’t rush, either.

A spade bit can quickly and efficiently bore holes into various materials. But, as we’ve covered, it results in jagged edges.

The Forstner bit step takes the longest. In any case, the additional effort will be well worth it if it yields admirable outcomes.

There is a happy medium with the hole saw’s speed. The balance is perfect. It is neither fast nor slow.

The highest cutting speed is achieved with carbide bars. However, they are not required for cutting. Detailing and polishing is where they really shine.

As a whole, the rate at which your tool operates shouldn’t be a major issue in your choice. No matter how quickly your drill can go, working with wood requires patience.

Hole Size and Depth

In general, each tool is offered in a variety of sizes. Nevertheless, the size ranges offered by individual tools typically have restrictions.

However, by overlapping in certain circumstances, you can generate larger gaps. Hence, this shouldn’t be a huge consideration.

The smallest of the three tools for cutting holes are called spade bits. They typically come in sizes ranging from 3/8 of an inch to 1 1/2 inches in length.

Forstners are a little bit larger. their sizes range from a quarter of an inch to two and one-quarter inches.

A carbide burr can have a cutting diameter of anywhere from 3/32 to 1 inch. However, its cutting depth can only go up to around 1 inch at most.

Because of this, they are perfect for detailing and shaping wood. But they are not suitable for making massive cuts or holes.

The hole saw is the most versatile of the three tools for boring holes. It also offers the largest option.

They are able to cut holes with diameters ranging from three-quarters of an inch to six inches!

Angled Drilling

Another potential application for drill bits is angle drilling. When drilling at an angle, auger bits perform the best.

It allows for angled drilling of up to 118 degrees. This is the maximum angle that can be achieved.

Forstner, Holesaw and Carbide burrs allow 90-degree angled drilling. This works wonderfully for perpendicular drilling, which is the method that is most frequently utilized.

When drilling at an angle, spade bits perform the least effective. The maximum angle of cutting at which it can be used is 10 degrees. This is the one that costs the least out of the whole group.


When it comes to cost, hole saw bits, spade bits, and auger bits can be purchased for anywhere from $15 and $25. Forstners and carbide bars are the only exceptions to this rule.

When compared to other types of drill bits, forstners have the highest price tag. The prices range from fifty dollars to sixty dollars.

The cost of carbide barrs is high because of the high precision and quality of their construction. They range in price from $30 to $40 per.

Which is the Best Hole Boring Bit?

Now that you are aware of the functions of these tools and how they operate, you can use them effectively.

It should not be difficult to understand when and how to take advantage of them.

Are you interested in a quick and simple cut, but you don’t care too much about how nice it might be? In that instance, the spade bit is the one you need to utilize.

An Auger bit is ideal if you don’t want to clean up the residuals like the spade bit. Its unique design allows the drill bit to carry out debris.

This is more efficient than spade bits. Also, the finished hole is much smoother.

Would you prefer the hole to be round and complete when you’re finished?

Also, do you want the diameter of that hole to be somewhere around a couple of inches? The hole saw is the most effective tool.

Do you aim to create a hole that is finished off with a smooth surface and a flat bottom?

Also, are you in such a rush to do the task that it’s causing you to make mistakes? The Forstner bit is the one that is recommended for your use.

Last but not least, a set of carbide burrs is a very useful item to have on hand. This is the tool to use if you want to add detail or if you require a powerful instrument for wood carving.

You must make full and effective use of every one of these instruments. If you are aware of their functions, you will be able to utilize them to their full potential.

Frequently Asked Questions

Are Forstner bits better than spade bits?

In some cases, Yes. Both the Forstner bit and the spade bit can make holes with flat bottoms in wood, plastic, plywood, MDF, etc. A Forstner bit is better because it makes holes with smooth edges and more accurate measurements.

Can I use a Forstner bit with a hand drill?

Yes, you can. Forstner bits make clean, precise holes in wood for woodworking. You can use a mobile power drill or a hand drill to make holes that are big and accurate. It can be done with different attachments for drill bits, like a Forstner bit.

Why do spade bits have a hole?

The hole on the end is put to use by pulling electrical lines back through the holes. This can be done after drilling only. They could also be used to hang the spade bit on a rack that is fixed on the wall, but that would be pushing it.


That’s all on Spade Bit Vs. Auger Bit Vs. Forstner Vs. Hole Saw Vs. Carbide Burrs.

Here is a tip, try to create an indent first on the drill location. This will be helpful for establishing a precise center point.

Have a great day.
