Klein Tools 86532 Metal Folding Tool for Duct Bending — 18 x 3-Inch, Folds to 24 ga Steel / 28 ga Stainless

Meet the Klein Tools 86532 Metal Folding Tool, a purpose-built partner for HVAC duct work and sheet metal tasks. Designed to help you create precise hems, pans, end caps, and drive edges, this folding tool blends practical control with rugged durability. The tool’s two folding depths and a sturdy build make it a reliable choice for daily trades work, without promising outcomes, but offering real possibilities for cleaner folds and better-tinished components.

The 86532 offers two fold depths: 3/8-Inch (10 mm) and 1-Inch (25 mm). This versatility lets you tailor the fold to the job at hand, supporting clean, consistent results across different sheet metals. The tool folds up to 24 gauge steel and 28 gauge stainless steel, expanding its range of potential applications while maintaining a compact, hand-friendly profile.

Integrated sight gauges provide visible references for depth alignment, reducing guesswork when you’re aligning multiple parts on a span or creating a sequence of bends. The tool is built from heavy-duty 16-gauge steel, which contributes to a solid, confident feel during use and helps it stand up to the rigors of shop and field environments.
