What Is a Nibbler?
A nibbler is a tool for cutting sheet metals with minimum distortion. It works by a die and punch oscillating at about 2,000 strokes per minute, as it cuts through your sheet material. You can use it to cut straight and curved lines, as well as circles in the sheet material.
When To Use a Nibbler?
Whenever you are working on bodywork, tanks, or sheet metal, a nibbler cutter devours steel, making it the ideal tool for the auto shop for repairs. Nibblers are also effective when cutting fiberglass, aluminum, or other sheet metal. If you like detailed and neat results, a nibbler cutter is the tool for you.
How Thick Can a Nibbler Cut?
The cutting depth of a nibbler depends on the material.
- Stainless steel plates 1.2 mm in thickness.
- Iron and steel plates 1.8 mm in thickness.
- Aluminum or copper plates 2 mm in thickness.
- Fiberglass or plastic board 2 mm in thickness.
Main Types of Nibblers
There are two main types of nibblers.
- Electric nibblers are driven by an electric current.
- Pneumatic nibblers use a compressor and are sometimes called air nibblers.
What To Look for in a Nibbler Drill Attachment
As with all attachments for your power drill, a nibbler cutter should have specific attributes.
Cutting Depth
Most nibbler cutting attachments can vary the depth they cut depending on the material. Sheet steel and iron generally have a thickness of 1.8 mm, while aluminum and fiberglass have a depth of 2 mm.
The bare minimum your nibbler should cut is 1.2 mm for stainless steel plates.
Electric
Electric nibblers are more crafting friendly because they are more convenient and have less heavy-duty tasks to fulfill. You will find that most hobbyist nibbler users will own an electric variety.
Pneumatic
Pneumatic nibbler cutters are better suited to sheet metal workshops and auto shops where their heavy-duty capabilities are put to good use. Pneumatic nibblers are far better placed to complete industrial-type uses.
Price
Price is always a limiting factor when shopping for a new nibbler cutter. They range in value, but you should still be able to get a decent nibbler for an affordable price.
How To Use a Nibbler Drill Attachment
Using a nibbler attachment is simplicity itself. Attach the shank into the drill chuck and tighten until it is locked in place. Power up the drill, and grip the handle of the nibbler. Start the drill going so the nibbler works at full speed and press it against the edge of the sheet metal.
As the die and punch make contact with the surface, it starts to nibble along the metal, throwing out shards of material. Apply gentle pressure when guiding the nibbler, but be firm with the grip, the nibbler does like to move about a lot.
When you reach the end, allow the nibbler to work free of the metal before releasing the trigger on the drill.
FAQs
Can a Nibbler Cut Curved Lines?
Nibblers are potent tools that are perfect for cutting curved lines. Due to their nibbling action, they can easily cut curves of various radii and shapes. Thanks to their compact design, they also work very efficiently in tight spaces such as automotive interiors.
A nibbler is an excellent option for making clean and precise curves when precision and accuracy are critical criteria for the job.
What Is the Difference Between a Shear and a Nibbler?
A shear is typically used for larger-scale projects, like when cutting heavy-duty steel; its mechanical components allow it to easily cut through without producing heat or causing too much wear and tear.
Nibblers are excellent for smaller projects, like making intricate cuts or getting into tight spaces that shears could not fit into. They can handle thinner metals but take a bit longer to complete the job than a shear does.
The downside of a nibbler is that it’s more likely to produce chips of metal which pilots have to sweep up afterward. But a shearing tool creates less waste and makes the cleanup process after the cutting much simpler.
What Safety Equipment Must You Wear When You Work with a Nibbler?
When working with a nibbler, wear approved safety glasses to protect your eyes from the flying metal chips produced by the tool. Long-sleeved shirts and pants are also recommended to protect your arms and legs from flying debris.
For extra protection, you should wear thick leather gloves, preferably with reinforced fingertips and palms. As a final measure, tie loose hair and secure clothing or jewelry away from the worksite.
Will an Air Nibbler Cut Stainless Steel?
The Air Nibbler is an ideal tool for cutting through plastic, aluminum, tin, and various other metals with up to 18-gauge rolled steel. This is because of the precise motion and speed that it provides to make smooth cuts.
As for whether or not it will cut stainless steel, the answer is usually no. Steel has a much higher density than the other materials the Air Nibbler works well on, so it’s generally not recommended if you are trying to cut this material.
You’ll need to seek out a tool that is better suited for hard metals, such as stainless steel instead.
What Is the Best Nibbler Tool?
The REXBETI Nibbler Tool is a powerhouse tool that is an absolute must-have for any metalworker. It’s designed with the highest quality, durable high-speed steel that will last through years of use.
For greater versatility in cutting and shaping, the 360-degree head rotates to make completing different tasks easier.
It cuts holes up to 11.4 inches in diameter and works on almost every type of sheet metal imaginable. Best of all, it leaves a burr-free edge finish!
