Buying Guide: Key Purchase Considerations
- Material compatibility: Assess if blades are optimized for stainless steel, ferrous, or non-ferrous metals. Some blades excel in stainless steel, while others focus on sheet metal or thicker profiles.
- Blade construction: Bi-metal blades typically offer better life in metal-cutting tasks, while carbide-edge blades can provide longer life on hard metals.
- Tooth design and pitch: Higher TPI (teeth per inch) yields smoother cuts in thinner metals; lower TPI blades cut faster on thicker metal but may roughen edges.
- Shank compatibility: Ensure the blade uses a universal T-shank or your tool’s specific shank design for a secure fit.
- Cut quality vs. speed: For precision work, prioritize blades with optimized tooth geometry and hardened edges; for rapid demolition cuts, choose blades designed for speed and heat management.
- Durability and heat management: Look for blades with heat-resistant coatings or cool-running designs to extend life during metal cutting.
- Blade life in your environment: Cordless vs. corded jigsaws can influence blade life; high-load tasks benefit from blades rated for metal and long life.
