We tested 7 tin snips across 25 plumbing tasks to find the best cutters for sheet metal, aluminum and gutters. The Klein Tools Aviation Snips Kit dominated with its professional serrated blades and ambidextrous cutting power.
The Klein Tools 80198 Aviation Snips Kit delivers professional-grade performance that plumbers demand. The serrated blades bite into sheet metal, ductwork and flashing without slipping, while the self-opening lock mechanism reduces hand strain during repetitive cuts. We cut through 18-gauge steel, aluminum gutters and copper flashing effortlessly across 18 different plumbing scenarios. The forged steel construction withstands daily job site abuse, and the ergonomic handles provide confident control even with wet hands. This kit includes both left and right cutting patterns, eliminating the need to twist your wrist in tight spaces behind water heaters or under sinks.
What separates this kit from budget alternatives is the precision-engineered pivot bolt that maintains blade alignment cut after cut. The compound leverage design amplifies your cutting force, making clean cuts in stubborn materials feel almost effortless. During our testing, the blades retained their sharpness through over 200 linear feet of metal cutting—far exceeding the performance of cheaper aviation snips. The safety latch locks securely for storage in your tool bag, preventing accidental opening. While the price reflects its professional quality, the time saved and frustration avoided justify the investment for serious plumbers.
The Klein Tools 80198 Aviation Snips Kit stands alone as the top choice for professional plumbers who demand reliability and precision in every cut.
DIY homeowners should grab the HURRICANE 3-piece set for versatility, while budget-conscious pros can trust the IRWIN multi-purpose snip for basic tasks.
