Milwaukee M12 FUEL 16-gauge Nibbler

The Milwaukee M12 FUEL 16-Gauge Nibbler Helps You Ditch Jobsite Shears for Something More Versatile

Whether you’re in the HVAC or roofing business or just general metalworking, cutting metal is an inevitable part of the job. In most cases, common jobsite shears can only perform straight cuts, making it difficult to maneuver in uniquely-shaped or compact spaces. Milwaukee designed the 2476-20 M12 FUEL 16-gauge nibbler to avoid this problem altogether. The tool gives you a lot of versatility when cutting corrugated or sheet metal.

Milwaukee M12 Fuel 16-Gauge Nibbler – The Big Deal

No, this is not a long-reach Milwaukee M12 FUEL Oscillating MultiTool!

Milwaukee claims that the M12 16-gauge nibbler has the same cutting capacity as its 18V competitors. It does this while dropping up to 25% of the weight. It has the ability to cut up to seven feet per minute when equipped with an M12 RedLithium XC 4.0 battery.

With more versatility than shears, the M12 nibbler can make unique cuts in spiral duct, sheet metal, and corrugated metal. You’re not regulated to just straight cuts with this tool. It also completes curved and 90-degree cuts. Nibblers, including the Milwaukee 2476-20, use a punch and die system to take small cuts out of the metal. This type of material removal gives you much more control over the shape and path of your cut.

As their first cordless nibbler in the M12 lineup, this tool uses M12 batteries and a brushless motor to ensure power in heavy applications. It’s rated for 18-gauge stainless steel and 12-gauge aluminum. It can also cut 16-gauge mild steel, even with its compact, lightweight design.
