Its Progresser for metal delivers rapid cuts and longer blade life across different metal thicknesses, making it a versatile choice for metalworking projects that involve varied materials.
Bosch T118G 5 pc. 3-5/8 in. 36 TPI for Metal
Bosch T118G blades are designed for very thin metals and sheet metal ranging from 17 to 26 gauge. The 36 TPI configuration enables smooth, precise cuts in ferrous and non-ferrous metals, with high-speed steel construction for extended blade life during straight cuts in metal sheets.
Bosch T118A 5 pc. 3-5/8 in. 17-24 TPI for Metal
Bosch T118A blades are suitable for sheet metal and thin metals, spanning 10-16 gauge thickness. The 17-24 TPI progressive tooth design provides smooth cuts across various thicknesses, while the high-speed steel construction supports long life in straight metal cuts.
Bosch T321AF3 3 pc. 5-1/4 in. 21 TPI Speed for Metal
Bosch T321AF3 blades are designed for cutting pipes, profiles, and sheet metal 10 to 16 gauge, with a 21 TPI tooth design for very fast cuts. Bi-metal construction enhances durability for metalworking tasks that demand longer blade life in demanding materials.
Buying Guide
- Material compatibility: For thick metal, prioritize blades labeled for metal or stainless steel, often with high-speed steel or bi-metal construction to resist heat and wear.
- Tooth configuration: Higher TPI (like 36 TPI) yields smoother cuts in thin sheet metal; lower TPI blades cut faster in thicker metal but may require more finishing work. For thick metal, mid-to-high TPI blades (21-24 TPI) are a solid balance.
- Blade type and shank: Most modern jig saws use T-shank blades. Ensure the blade set includes universal T-shank compatibility or a package that matches your tool’s shank style.
- Life and durability: Bi-metal blades tend to last longer in metal cuts due to tempering and design that handles heat. Consider carbide-edge options for stainless steel and harder metals.
- Width and thickness: Thicker blades are more rigid and resist bending when cutting thick metal sections. Ensure your blade length (often around 3-5/8 in.) fits your jig saw’s required reach.
- Application range: Some blades are optimized for specific metals (stainless steel, aluminum, carbon steel). For mixed projects, select versatile blades labeled for metal or multi-material use.
- Tool compatibility: Check that the blade’s shank type and overall length are compatible with your jig saw to avoid installation issues or reduced performance.
When selecting blades for thick metal projects, consider a balanced mix of durability, cutting speed, and compatibility with your jig saw. The showcased options provide a spectrum—from high-speed steel for efficient straight cuts to bi-metal designs offering longer life under heavy use—helping you handle metalwork tasks with confidence and precision.
