Milwaukee Aviation snips are built for long life and durability. Forged blades deliver up to 10X more cuts than cast blades. Bolt lock ensures the blades won't loosen and chrome plating provides rust protection. The flush pivot bolt won't hang up on material for easy use. The metal lock secures the tool for storage and is easily operated with one hand. The 3 pc. set includes left, right, and straight aviation snips.
