Wondering which tool to use? A nibbler or a jigsaw?
According to Aaron Barnett of BangingToolbox: If you’ve been staring at a metal workpiece trying to figure out how to perform a certain cut, as you’re considering both a jigsaw and a nibbler.
Nibbler vs jigsaw are not so odd comparisons for all metal-cutting jobs. Both tools are the king and queen of power tools that are great at cutting intricate shapes and patterns.
So if you need to choose one, you should know which tool is better for that specific cut.
In this article, we’ll show you why you can have them both and how to use each better.
So, what do jigsaws and nibblers have in common?
Although nibblers and jigsaws can be completely different in their functionality, they can share some of the same characteristics.
- Jigsaws and nibblers are both cutting tools you can use on metal.
- Both the blades use a back-and-forth motion to cut through metal. However, the different blades have different designs.
- The tools are powered by compressed air or electricity.
- Both cutting tools excel in cutting curves, patterns, and intricate shapes faster and more efficiently than other handheld power tools.
What is a nibbler?
A nibbler is a handheld metal-cutting tool, specifically designed for chopping metal sheets.
This cutter uses a punch-and-die mechanism to create a powerful cut.
What we love is the inside mechanism that produces clean cuts free of sparks and heat.

Pros
- Needs little-to-no deburring work
- Better control in tight spaces
- Less risk of damaging the metal sheets you will be shaping
- Creates less heat with no sparks
- Reduced risk of breaking blades
- Ideal for thicker metal roofing as well as thinner sheets
Cons
- Cannot cut wood as a jigsaw can.
What is a jigsaw?
A jigsaw is a handheld cutting tool that uses a reciprocating blade, cutting with an upward and backward movement.
The replaceable blade availability is versatile for cutting different types of cuts and materials with different blade choices.

Pros
- Performs different cuts
- Can cut through various material types such as wood, metal and plastic.
- Faster cutting action
- More affordable
- Larger cutting capacity
- Cuts through thinner metal sheets.
Cons
- Limited cutting depth
- Produces heat and sparks while cutting
- Less control leaving messy cuts
- Slow to cut metal
Uses
Although both tools can cut metal, each tool’s use and application are different.
Where to use a nibbler?
Nibblers are specifically designed for cutting thin sheets of metal. It cuts through aluminum, brass, copper, and steel. You can use a nibbler for the following purposes:
- Cute metal roofs to size and shape doing both straight and curved cuts.
- Use for HVAC ductwork cutting jobs.
- Cut and shape automotive body panels.
- Cut electrical enclosures.
- Sheet metal fabrication.
- Metal artworks.
- Making metal signages.
Where to use a jigsaw?
You can use a jigsaw for a wide range of building and DIY applications.
- Shape wood and metal into circles or odd patterns.
- Cut different metal small pieces like metal plates, sheets, brackets, or pipes.
- Cutting holes in walls.
- Plumbing cutting jobs.
- DIY projects.
- Trim door frames.
- Plunge cuts (for woods).
- Cut sheets, including MDF and particle boards.
Cutting Capacity
When the day comes to your cutting capacity on metal sheets, Nibblers can cut thicker metals. And can cut from 10 to 18 GA steel. That is around 1/20” or 1.27 mm.
Meanwhile, jigsaws can cut 000000 GA or 12.7 mm. It can even cut up to 15 mm stainless steel sheets. This makes jigsaws ideal for thicker metal sheets.
But because of their blade designs, jigsaws can accommodate cutting jobs for metal workpieces such as rebars, and pipes. But cutting is slower than an angle grinder.
Cutting precision
Jigsaws and nibblers both work great for cutting intricate shapes, curves, and patterns.
But when it comes to precision, nibblers are the clear winner here because the tool utilizes a shearing action.
This shearing action may not require after-cut finishing work like sanding or filing down burrs. See how Makita nibblers did well on our review.
In the case of a jigsaw, this tool uses a reciprocating blade which often leaves a jagged cut.
You may have to sand or file the edges additionally to smoothen the surface.
Noise and vibration
When the operation comes to noise and vibration, a nibbler is much quieter than a jigsaw.
The nibbling action also produces less vibration than the fast-paced reciprocating action of a jigsaw tool.
This action shakes the jigsaw tool, causing stress on your hands as the operator.
For this reason, my nibbler makes a more comfortable tool considering less noise and vibration.
Metal-cutting jobs
1. Straight cut
Both tools are applicable to straight cutting. However, a nibbler can cut thicker metal sheets more precisely since the tool is easier to control. You’d still need a straight-edge guide.
Nibblers can cut straight lines slower because of the chewing action. Although, it is not advisable to use a nibbler for cutting long straight lines over a period of time.
A jigsaw cutter will do the cutting job better if you have thicker bits of metal and use a bi-metal straight-cutting blade.
However, if you replace it with the usual bi-metal blade for metal, you may still have to smoothen the edges. You can also use a guide for a straighter cut.
The most appropriate tool for straight cuts in sheet metal is – electric metal shears.
2. Curved cut
For curved cuts, the nibbler is the winner here.
Aside from the tool needing no additional finishing tasks, it can make complex curved cuts in tighter spaces. You can also maneuver a nibbler tool better.
Meanwhile, jigsaws can cut efficiently with the gentle and gradual cutting of curves.
With the expertise or consistent practice in handling the tool, you can also make nice curved cuts with a jigsaw.
The good thing about jigsaws is they are not limited to cutting curves in sheet metals but other materials too like wood.
3. Notched cut
For cutting notches on metal, the nibbler is the clear winner here.
Especially if you are working on thicker and harder metal, nibblers will create a more precise and accurate cut.
As the nibbling action makes working easier while cutting notches with minimal burning. Meanwhile, cutting notches on metal with a jigsaw may be not a first class idea.
With the tight spaces required to cut, it seems impossible or hard to do it with a jigsaw. However, it can cut tighter square corners if you can fit the blade into the corner.
If you are working to make a notch in wood, a jigsaw can deliver.
4. Holes
Jigsaws can cut clean holes both on wood and metal with a compass.
The saw cuts better with larger holes than a nibbler. However, if you are trying to make small holes, a nibbler is a better option.
A hole-cutting job can be done best with a hole saw as the tool can achieve different sizes, as a result of the right drill piece.
For smaller holes, a drill will do with a standard metal drill bit. However, if you have to choose between a jigsaw and a nibbler, go for a jigsaw.
5. Beveled and angled cut
Jigsaws can make better beveled or angled cuts than a nibbler.
Because a nibbler is limited to a straight up-and-down shearing action, creating precise angled cuts can be time-consuming and harder to achieve.
You may tilt the jigsaw from the base plate so the tool may perform that beveled cut precisely after the blade is locked into position.
6. Perforated cut
Perforated cuts are spaced holes cut on metal.
Because of the complex and tight spaces needed to perform the cut, you can perform this job better with a power drill.
The punch-and-die mechanism on a nibbler won’t work as it cuts a continuous line.
And trying to drill holes out with a jigsaw seems not possible.
7. Edge-cutting
Both tools work well with edge-cutting.
However, one tool may specialize in some applications. If you are making straight-edge cuts, do it with a jigsaw.
Here’s a tip, use a guide if you want even straight edges on different sides.
For curved edge-cutting, use a nibbler. Nibblers make clean curved edges with minimal distortion. You can also trim the edges with tin snips afterward.
Cutting on metal workpieces
1. Corrugated metal sheets
When cutting corrugated metal sheets, a nibbler is your best option.
The punching blade makes cutting through corrugated sheets a breeze in the stadium. A nibbler is also great with corners, radius, and holes for minimal distortion and cleaner cuts.
If you don’t have a nibbler, a jigsaw is a first class alternative. Check out our corrugated metal cutting guide on this page.
2. Sections for vents or ducts
For cutting sections for vents and ducts, you can use both according to the requirements of the metal cutting job at each stage.
If you will cut rounded or circular ducts, your best option is a nibbler. Ductworks need high accuracy, so using a nibbler is your best option.
But if you are cutting rectangular or angular cuts on vents or ducts, a jigsaw cuts better since it cuts into a sharper corner.
3. Metal tubes or pipes
Between these tools, a jigsaw can cut metal tubes and pipes if the metal is thin enough for the tool’s maximum gauge rating.
Although the best tool you can use for cutting thicker metal tubes is a brand new chop saw, band saw, or pipe cutter. A nibbler would only suit thin-walled tubes.
4. Metal rods or bars
Again this job is better done with a chop saw or a cordless angle grinder.
But if you must choose between a jigsaw and a nibbler, a nibbler is inappropriate for the thicker metal workpiece.
Check our rebar-cutting guide for more options.
5. Metal plates
The choice of your tool for cutting metal plates depends on thickness.
For thicker metal plates, a jigsaw might struggle but be more appropriate than a nibbler.
Thin metal plates do well with an angle grinder. Using an abrasive blade, you can cut thick metal pieces with better control and less vibrations.
Key Takeaways
Overall, the choice between a nibbler and a jigsaw will depend on your usage, the material, the workpiece, the thickness, and the cutting techniques you have.
Both tools need practice to get good results with both your jigsaw and nibbler tools.
You can use both tools for most metal-cutting jobs. You only need to get used to each tool’s internal mechanism and how they work with different-sized pieces of metal.
Working with metal-only cutting blades will require you to invest in a reliable nibbler tool. If you also need to cut other materials aside from metal, check our recommended handheld jigsaws.
