Air Angle Cutter / Nibbler

Air Angle Cutter / Nibbler
(Also known as Pneumatic Sheet Metal Cutter / Air Nibbler / Air Angle Shear)

An Air Angle Cutter / Nibbler is a pneumatic sheet metal cutting tool designed for precise trimming, cutting, and shaping of metal sheets, panels, or ducts without distortion or burning. It uses compressed air to power a reciprocating punch and die or rotating cutter disc, producing clean, smooth cuts through various materials — including aluminum, mild steel, stainless steel, and plastic. This tool is widely used in automotive bodywork, HVAC duct fabrication, sheet-metal production, and construction maintenance.

Working Principle

Air Supply: Compressed air drives an internal motor or piston mechanism.

Cutting Motion:

In Angle Cutter types, a rotary cutting blade trims through the material.

In Nibbler types, a small punch rapidly moves up and down through a die, “nibbling” small pieces of metal to form a smooth cut path.

Continuous Operation: The tool cuts continuously as it moves along the material, leaving minimal burrs and deformation.

Key Features

Clean Cutting with No Sparks: Ideal for painted or coated metal surfaces.

Compact 90° Angle Head: Provides access to tight or confined spaces.

Smooth, Distortion-Free Cuts: No heat or warping during operation.

High Speed & Precision: Up to 3,000 strokes per minute for efficient cutting.

Adjustable Cutting Direction: The head can often rotate 360° for flexible use.

Durable Hardened Punch and Die: Long life and easy to replace.

Lightweight Aluminum Body: For excellent maneuverability.

Applications

Cutting and trimming automotive body panels and truck cabs.

Shaping HVAC ducts, sheet metal enclosures, and roof panels.

Trimming stainless steel, aluminum, and plastic sheets.

Workshop repair, assembly, and prototyping operations.

Advantages

Cleaner edges than abrasive wheels or manual shears.

Safer — no sparks, burns, or heat distortion.

Compact design reduces operator fatigue.

Long service life and easy maintenance.
