Spade bit vs hole saw, which tool better fits your drilling application?
A spade bit is a flat piece of metal with a round spindle that fits into the check of a drill. A hole saw has a steel cup machined around one edge with saw teeth (cutting blade).
The cutting blade is mounted to a center mandrel that holds a twist drill bit. The twist bit centers the hole, and the cutting blade cuts a circular cutout.
Spade bits are mostly ideal for woodworking, while hole saws are used more frequently for woodworking and metal cutting.
These are just the highlights of this battle. Let’s dig a little bit deeper and find out which of the two offers a better drilling performance.

The Dewalt DW1586 has a heavy-duty hex shank with ball groove, which is great for impact drills, large diameter rod, and reduced slippage.

3. Bosch DSB5010 Daredevil Spade Bit Set – Best Threaded Tip
The Bosch DSB5010 Daredevil kit provides industry leading drilling performance for professional woodworkers and DIY enthusiasts.
- Ten-piece standard spade bit set
- Full cone threading
- Speed wave paddle
- Great spur and reamer
- Hex shank with power groove
These spade bits have a threaded full cone tip, which is great because the tip will pierce into wood quickly and effortlessly.

4. Milwaukee 49-22-4105 19-Piece Hole Saw Kit – Overall Best
The Milwaukee 49-22-4105 is a unique generation of hole saws, which are engineered to offer up to fifty percent longer life compared to the competition.
- Set of 19 pieces
- Ice hardened
- Positive rake angle
- Matrix II bi-metal teeth
- Reduced tooth back
These hole saws have undergone a proprietary cryogenic hardening process, which is great because they’re consistently hard and more durable than conventional models.
Another good feature is the positive rake angle, which cuts more aggressively and effectively while deeper gullets get rid of chips faster.
But the thing is, the latches of the case may be a little bit harder for some people to open for the first time.
- Case is very strong and durable
- Ice hardened design is highly durable
- Positive rake angle cuts effectively
- Kit offers a variety of sizes for different applications
- Deep gullets remove chips faster

5. Craftsman CMAH1SET13 Hole Saw Kit – Best Bi-Metal Design
The Craftsman CMAH1SET13 Hole Saw Kit allows for rapid changing of sizes. So, you can get your work done faster and move on to something else.
- Bi-metal construction
- Comes with most popular sizes
- Durable hole saw arbor
- Comes with Heavy-duty kit box
- Metal and wood cutting
This kit has bi-metal hole saws, which is great because they’re compatible with wood and metal and they also reduce vibration during cutting.
Another good feature is the arbor, which is easy to use, smooth, has strong wear resistance, and removes chips effectively when cutting wood or metal.
What I don’t like about this set is the lack of instructions for putting together the hole saw bit, hole saw driver, and centering bit.
- Bi-metal design cuts smoother and faster
- Pitched teeth reduce vibration
- Assembled arbor is wear-resistant
- Removes chips effectively than conventional designs
- Strong, durable kit box included
- Could be easier to assemble with an instruction manual
- Arbor doesn’t have dual metal prongs
The Craftsman CMAH1SET13 is really a great set for professionals and DIYs. Not to mention that you can easily switch sizes once you figure out how to put the parts together.

6. Dewalt D180002 Hole Saw Kit – Most Rugged Kit Box
If you want to cut accurate round holes in metal or wood, choose the Dewalt D180002 Hole Saw Kit. This kit will do the job quickly and precisely.
- Bi-metal construction
- Innovative tooth and set guide
- Toughened backing plates
- Variety of sizes included
- Comes with a rugged kit box
They have a bi-metal construction, which is good because they are long-lasting and the variable pitched teeth structure helps minimize vibration.
These hole saws can be used with or without the drill bits. So, if you want to cut a disc without a hole in the center, you can choose not to have the bits in the arbor.
But the problem is, you will need to have two different size drills in order to be able to use all the provided saw blades.
- Bi-metal construction is very durable
- Variable pitched teeth minimize vibration
- Can be used without the drill bits
- Toughened backing plates prevent marring
- Rugged kit box is provided

- Some saw blades are painted halfway
The Dewalt D180002 is a hole saw kit that will meet your expectations when cutting metal or wood. You may need to have two different size drills, though.

How To Pick The Right Spade Bit
There are a few things to consider:
The shank is the smooth metal shaft in between. The best design to look for is a quick-change hex shank that has grooves for preventing falling off and reducing slipping. It also has to be a universal fit for most drill driver tools.
Another important feature that a good spade bit must have is unique cutting spurs. You can look for scribing spurs on the corners for making cleaner entry holes or double side spurs for grabbing as well as carving wood away.
How To Pick The Right Hole Saw Bit
There are a few factors to take into account:
The cutting blade is one of the most important parts of a hole saw. It is the metallic cylinder with a wider diameter.
The cutting blade is available in different diameters, ranging from 1/2 to 8-1/4 inches. When buying a set, make sure it has all the important sizes you will need for your application.
The tooth configuration of hole saws is selected mainly on the basis of hardness, resiliency, and abrasiveness of the materials to be drilled.
There are two popular configurations: serrated saw teeth and gulleted/square saw teeth. The serrated teeth provide penetrating bites, while gulleted teeth provide more aggressive bites.
Spade Bit Vs Hole Saw – What Are The Differences?
Spade bits, as the name implies, have the shape of a spade. Their design makes them ideal for boring holes. They are best suited for rough work where speed is preferred over clean cuts. They can drill holes ranging from 1/4-inch to 1-1/2-inch in size.
Hole saws are primarily designed for making holes. Unlike a spade bit, the design of a hole saw consists of a cutting blade and a mandrel.
Spade bits are ideal for boring holes through wood. They are used to drill rough holes in areas that aren’t generally visible, or areas that will be covered up later. For example, plumbers and electricians use spade bits to bore holes in wood for inserting pipes or wires.
Hole saws are preferred for applications that require cleaner cuts. They can cut large-diameter holes. This is so, since they cut out a perimeter of a hole instead of drilling into the material.
Common applications for hole saws include: door hardware installation, installing light fixtures, installing drainage pipes, and cutting vents in masonry to mention a few.
Forstner Bit vs Hole Saw
But there’s another player in the hole-boring game. What is a Forstner bit and what does it do differently from the standard hole saw and spade bit?
A Forstner bit is a cutting tool that is designed to drill smooth, flat-bottomed holes with no tear out at the rim.
While a standard hole saw and spade bit are guided by their centers, a forstner bit is guided by its rim. Because of its unusual design, a Forstner bit can bore overlapping holes.
Spade bits are perfect for making rough drill holes in wood, and that is why they are so popular among plumbers and electricians.
Hole saws; on the other hand, can make clean large-perimeter holes for a wide range of applications. They are useful to plumbers, electricians, woodworkers among other users.
The Dewalt DW1587 Spade Bits Set wins in shank and cutting spurs designs, which are useful for reducing slipping and producing cleaner entry holes.
The Milwaukee 49-22-4105 19-Piece Hole Saw Kit wins in the variety of cutting blade sizes and superior tooth configuration for a wide range of applications.
