Best nibbler tool for cutting metal roofing?

1. Choose the right brand.

Makita and Hitachi make the best nibblers.

The models from these brands are generally very durable and can cut through a wide variety of materials.

The blades found on both these tools are tested by our team to hold their edges well, which is essential when you need to do a lot of cutting jobs.

For compressor models, check out the nibblers from Ingersoll.

3. Is the tool Portable enough for your needs?

Cordless battery-powered nibblers always have the edge over corded models in terms of portability.

This could be an important factor if you have to work in tight spaces or places where there is no power outlet nearby. Compressed air nibblers are usually pretty powerful, but the hose makes for a less portable option.

4. Get a price that’s good in the long run.

Nibblers are fairly simple tools, but the best models aren’t cheap. I generally recommend getting a pro-level tool for even DIY work.

But for small cutting jobs and occasional DIY cutting, you can get the job done with similar results with an appropriate drill attachment–or even tin snips without having to purchase a nibbler. If you are a professional, an electric nibbler can be your top metal cutting tool.

5. Is the cutter head durable, and can you replace it?

You need a nibbler that can cut through a wide variety of metals.

Although you will probably be using your nibbler for cutting sheet metal, the device should be able to handle not just corrugated iron but other harder metals without losing the sharpness on the cutting edge too quickly.

And then, consider buying a replacement cutter head or two, so you have extras ready for when you need to replace the current blade.

Make sure to include extra punches for when the original wears out so that you are not stuck with your tinsnips all day.

Electric nibblers can cut through metal the quickest and are arguably the easiest metal-cutting tool to use in general. Expect the Makita to make very clean cuts and do an excellent job at cutting.

Nibblers have no problem cutting sheet metal around corners, angles, and even intricate shapes. I would say the only drawback is the price for DIY, as there are cheaper tools for cutting only straight lines, like electric shears.

For building and construction, however, electric nibblers made by Makita, Hitachi, and Fein perform better than other metal cutting tools, utilizing good cutting design and power to make the – best tool for cutting sheet metal for roofing and building work.

Makita nibblers have more grunt and can cut thicker gauges than air nibblers and other electric nibblers with both a 16 and 18-gauge model with a 5 or 6.2amp motor.

The Makita JN1601 16 Gauge 5 Amp nibbler is the mother of all metal cutting power tools.

The model is a better-sized shape for general-purpose use and is easier to handle while being a bit cheaper than the bigger options!

The Makita JN3201 nibbler runs on 6.2 Amps of power, making it the most powerful nibbler to be able to cut up to 10 gauge roofing.

Air Nibblers are easier to use because the design is smaller and features a smaller, easier-to-grip handle to hold onto.

The unit is cheaper to source based on the simplicity of the design compared to an electric nibbler if you already have a portable air compressor.

Even still you don’t need a big compressor just look for one with a low DB rating so that you don’t have to deal with too much noise in compression time.

Air nibblers cut fast and smoothly and are recommended for car panel work or more detailed roofing jobs as they are found to feel easier to hold, move, and control with the smaller size and lower weight.

Air-powered nibblers are a little less portable, though beyond the reach of the compressor hose.

There have been a few variations on this basic manual hand nibbler design over the years. Adel is one company that continues to manufacture hand nibblers based on standard styles, which are commonly called “punch and die” nibblers.

Companies such as Bessey took a different approach, designing nibblers that departed significantly from conventional designs.

The company’s Super Nibbler is widely considered to be a significant step forward in a manual nibbler design. Super Nibblers differ from conventional nibblers in that the tool is held parallel to the workpiece.

Although these types of nibblers still have only a single blade, the teeth cut the material in pretty much the same way! As shears, which is why we often call these guys nibbler shears.

With Super Nibblers, most of the cutting action comes from below the workpiece.

Although the ends don’t eject shards in the same way as conventional nibblers, the ends still have shields for protection against the bits of metal that break off from the main workpiece.

These Super Nibblers are usually longer than most other types of hand nibblers and require much less pressure, so the blades tend to last longer.

Here are more options to cut metal manually.

1. Tin snips

Aviation snips are the cheapest option by far.

You can get a nice controlled cut with a top-tier pair of snips, and you can cut across big sheets fairly easily, but only if you are directly cross-cutting the iron sheet.

The of-cut needs to be big enough to bend out the way to prevent jamming the tin-snip blades.

However, tin snips are less effective at cutting big cuts on metal sheets, as they can be pretty slow to work with.

Tin snips are best for cutting flashing and tidying up edges that you haven’t got perfectly with an electric tool.

2. Electric-shears

Electric shears come as either a dedicated power tool or as attachments for impact drivers. The great thing about electric shears is the price, and having a portable tool that isn’t tethered to a compressor hose or a lead.

Electric shears can cut through metal sheets fairly easily with a straight cut but aren’t good at cutting around corners, angles, or cutting along the corrugated iron.

Although cross-cutting is the majority if not all the cutting that needs to be done as you can just give corrugated iron sheets extra lapping to suit.

Electric metal shears can sometimes be cheaper than nibblers and can be powered by just your Makita or Dewalt 18v drill. Find out more here, but a nibbler can cut all these cuts effectively without jamming.

Keep in mind that nibblers can take as much as 6 mm of material off the piece you are cutting.

Not for tight-cutting

They are, therefore, less suitable for workpieces that you need a tight cut, for example, a flashing.

One of the best things about nibblers is that they can create cuts without warping or distorting.

This quality makes an excellent choice for situations where you want to preserve the appearance of the material.

One of the main advantages that nibblers have over electric shears and tin snips is that the tool is less prone to jamming. This is because the blade cuts a sizable amount of material off the workpiece in each stroke.

Most nibblers punch fairly wide holes as the cutter head runs. This gives the mobility and ability to cut around corners easily–which is where jamming usually takes place–nibblers are not likely to get caught in the material as compared to other tools like electric shears and tin snips.

Nibblers can even cut over corrugated metal sheets efficiently, even when cutting at an angle.

Try that with shears or tin snips, and your work will probably be messy and take much longer to complete.

Furthermore, nibblers make much smoother and more consistent cuts than even your best pair of shears or snips ever could.
