The Bosch T118G is designed for very thin metals and sheet metal cutting. This 5-piece set uses a 36 TPI tooth design to provide smooth cuts in 17–26 gauge materials, including ferrous and non-ferrous metals. Crafted with high-speed steel, the blades are optimized for straight cuts with extended life in thin materials. Ideal for projects requiring precise, clean lines in light sheet metal applications.
Bosch T321AF3 3 pc. Metal Blades
The Bosch T321AF3 set focuses on pipes, profiles, and thin sheet metal from 10 to 16 gauge. With a 21 TPI tooth design and bi-metal construction, these blades enable fast, smooth cuts and longer blade life in metal cutting tasks. They are well-suited for intricate cuts around tubing and metal profiles, offering versatility across metalworking projects.
Bosch TPM005 5 pc. Pro-Metal Set
The Bosch TPM005 Pro-Metal set delivers a comprehensive selection for metal cutting with multiple blade types. This set includes options designed for stainless steel and other metals, featuring carbide edges for stainless steel to deliver durable, high-performance cuts. The Progresser design helps provide fast cuts with improved life across varying metal thicknesses, making it a solid choice for professionals working with metal fabrication.
Bosch T118A 5 pc. For Metal
The Bosch T118A set is designed for sheet metal cutting in 10–16 gauge range. With a 17–24 TPI progressive tooth design, these blades deliver smooth cuts across different thicknesses, combining high-speed steel construction for longevity. The progressive teeth help maintain control while cutting varying metal thicknesses, reducing chatter and ensuring consistent results in production or hobby metalwork.
TopsTools T118A 91mm Blades
The TopsTools T118A blades are designed for broad compatibility with most jigsaws, using a T-shank and 21–24 TPI tooth design that supports smooth metal cutting across a range of thicknesses. This 25-piece kit emphasizes value and versatility for metal cutting projects, making it suitable for both professional shops and DIY tool users seeking reliable blades for frequent metal work.
Buying Guide: Key Considerations For Jigsaw Blades For Sheet Metal
Choosing the right blade depends on the metal type, thickness, cut quality, and your jigsaw’s compatibility. Here are essential factors to consider when selecting blades for sheet metal:
- Material compatibility: Ferrous vs non-ferrous metals require different tooth patterns and edges. Blades with carbide or bi-metal construction offer longer life on stainless steel and hard metals.
- Tooth pitch: Higher teeth per inch (TPI) yields smoother cuts but slower progress. Lower TPI blades cut faster but can leave rougher edges on thin metals.
- Blade construction: High-speed steel (HSS) blades are common for metal cutting; carbide-edge blades provide superior wear resistance on stainless steel and tougher alloys.
- Tooth design: Progressive teeth help when cutting varying thicknesses; straight tooth designs are often preferred for clean, straight cuts in sheet metal.
- Blade width and length: Ensure the blade length fits your jig saw’s capacity and that the blade width suits the cut type (curves vs straight lines).
- Jigsaw compatibility: Most modern blades use T-shank designs; verify your tool accepts T-shank blades to avoid loose fit or binding.
- Cut quality vs speed: For precise finish, prioritize blades with finer TPI and smoother tooth geometry; for rough or fast cuts, lower TPI blades may be acceptable.
When choosing blades for metalworking, consider having a small set that covers light sheet metal, stainless steel, and thicker metal sections. This approach helps maintain blade life and ensures clean, repeatable cuts across a variety of projects.
Always follow safety guidelines when cutting metal: wear eye protection, use clamps to secure work, and allow proper blade cooling and lubrication if required by the material and blade design.
