Nibblers are the ultimate sheet metal cutting tool.

Many of you won’t be familiar with a sheet metal nibbler, but the best nibbler drill attachments make life a lot easier when it comes to cutting through sheet metal. For those creative types, or anyone looking to work in detail on sheet materials, this is the best tool to use.

We rundown the best nibbler drill attachments to see which is the best.


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.
