What You Should Know About Sheet Metal Nibbler (FAQs)

Whether you’re not sure if nibblers are what you need for your work or if you have a question regarding them, we’re here to help you out!

Is it better to buy a nibbler or shears?

The two most popular tools for cutting sheet metal are nibblers, which I discuss in this post and shears. In most instances, you’ll be able to complete your task using any of them. You should bear in mind, though, that nibblers are considerably more precise and may cut clean radiuses.

What are the types of nibblers?

There are two types of sheet metal nibblers: hand nibblers and power nibblers. While the former requires human effort and functions similarly to scissors, the latter is propelled by either electricity or compressed air.

There are two types of electric nibblers: cordless and corded.

Which one should you choose?

You may be able to get away with utilizing hand nibblers instead of power nibblers if you need to cut reasonably thin sheets of metal and just have a few tiny cuts to make. If you need to perform any more work or often cut sheets, I suggest buying one of the power nibblers or a drill attachment.

Unless you already own a compressor in your workshop, I suggest buying an electric compressor. Metal nibblers should be used unless you need the additional power that corded tools offer or are on a budget. They will be a lot easier to use, and you will not have to worry about being tangled in the cable.

What is the finest brand of nibblers?

Knipex is my personal favorite when it comes to hand nibblers. Personally, I suggest Makita for power nibblers since it is the brand of tools with which I have the most expertise and which has never let me down.

If you currently own power tools from another manufacturer, check to see if they also sell nibblers. It’s wise to stick with the same brand, particularly if you’re utilizing cordless power equipment.

Sheet Metal Nibbler Characteristics To Look For

Strokes Per Minute (SPR) – This refers to how many times the nibbler’s sharp blade moves against the fixed die in a minute or how many times it cuts the metal. You don’t need to go for the highest number of strokes per minute, but you should aim for between 1,500 and 2,200 SPR.

Cutting Radius – A nibbler’s cutting radius should be between 1″ and 4″. This is dependent on the size of the hole you’re attempting to cut and the material you’re using.

Cutting Capacity – This refers to the material thickness that the nibbler can cut through. Nibblers are capable of cutting up to 18 gauge steel. Before you buy a nibbler, consider the material you’ll be dealing with. You may not need such strong and costly equipment.

What’s The Best Way To Utilize A Sheet Metal Nibbler?

  1. Any contractor or carpenter who has used a jigsaw and subsequently moved to nibbler will inform you how the latter is operated in the same way as the former. The main difference between a nibbler and a cutter is that a nibbler does not come with a table that rides along with the material as it cuts. Our testers devised a very effective method of compensating for the lack of this feature: they ensured that the body of the best nibbler was always parallel to the metal while in use. This helpful hint should be remembered to prevent the tool from binding.
  2. As many of you are aware, if you intend to cut in the center of the surface, it is only reasonable to use a drill to create a starting hole. To determine the minimal radius of a starting hole, consult the encasing of the best nibbler. When we needed to terminate the cut in the center of the surface, on the other hand, we found it far easier to back the machine out of the cut rather than drive it out of the kerf.
  3. While working with the best nibbler and it is in the middle of cutting, you will notice that you can simply alter the direction of the metal component, or you may opt to spin the machine instead, in the case of smaller materials. The greatest nibbler comes with an efficient die holder that performs the work of rotating to minimize the risk of the nibbler bottoming out against possible hindrances.
  4. The best nibbler should guide the shards of metal that frequently ruin the smooth surfaces of completed metal items downwards. Because these very sharp metal fragments come out of the machine at any time while cutting, our testers had to be cautious to prevent catastrophic injury. During the testing, our researchers observed that the final pieces had some uneven and damaged edges that required to be smoothed up after they were cut. These sharp edges and burrs may be polished using a grinder or a metal sander, or you can flatten them out entirely with a hammer, depending on the overall aim of the job at hand.

Conclusion:

Makita is a well-known power tool company that produces a broad range of electric power tools, including a variety of nibblers.

The Makita JN1601 nibbler is ranked first in this post because it is one of the most powerful choices. With the assistance of its 5 amp electric motor, it can provide high levels of performance. The 5 amp electric motor in this nibbler type can cut up to 16 gauge metal sheets.
