Introducing the Bosch 3-5/8 in. Bi-Metal T-Shank Jig Saw Blade, 18 TPI, 5-pack — a purpose-built solution for clean, dependable cuts in medium-thin metals. Designed for professionals and serious DIYers, this blade pairing blends durability with precision to tackle sheet metal, thin steel, aluminum, and other light-gauge materials with confidence.
Key advantages that set this blade apart
-
Bi-Metal construction combines resilience and flexibility, delivering longer blade life and fewer tooth breaks when cutting through metal sheets and panels.
-
18 TPI targeting metal work provides smooth, steady cuts with reduced burrs in 5/64" to 7/32" thick materials, making it ideal for precise internal cuts and tight curves.
-
T-Shank design ensures quick, secure blade changes on most jig saws that use T-shaped blades, minimizing downtime and compatibility hassles.
-
Exact dimensions for predictable results — 3-5/8" length with a blade thickness of 0.04" and width of 0.3" strikes a balance between rigidity and maneuverability, letting you handle both straight lines and gentle arcs with control.
-
Convenient 5-pack means you’re ready for multiple projects or back-to-back cuts without waiting for a new blade, keeping your workflow uninterrupted.
Ideal use cases
- Cutting thin steel, aluminum, or copper for HVAC duct work, metal flashing, or sign fabrication.
- Sheet-metal projects in workshops, garages, or fabrication shops where clean edges and minimal burrs matter.
- Curved or complex patterns in medium-thin metals where control and blade longevity are essential.
Practical guidance for best results
- Use at a steady, moderate feed rate to maximize blade life and achieve clean edges.
- Match your jig saw’s speed to the material thickness within the 5/64"–7/32" range for optimal performance.
- Clamp material securely and avoid twisting or forcing the blade, which can cause premature wear.
With Bosch craftsmanship behind every cut, this 5-pack of 3-5/8" bi-metal jig saw blades is a reliable choice for metalworking tasks that demand precision and durability. If you’re tackling thin-gauge metal projects, these blades are built to deliver steady performance, minimize waste, and keep your projects moving forward.
