Bosch T321AF3 3-Piece 5-1/4 In. 21 TPI Speed for Metal T-Shank Jig Saw Blades
The Bosch T321AF3 set is designed for metal cutting with a 21 TPI tooth pattern, optimized for smooth and fast cuts on pipes, profiles, and sheet metal in the 10-16 gauge range. Bi-metal construction provides durability for repeated use on tougher metals, including tubes and angle iron. The kit includes blades suited for thin metals from 1/16 to 1/8 inch thick and is a strong choice for experienced users tackling versatile metalwork projects.
BOSCHT 1018AFP1P 10 Inch 24 TPI Precision Cutting T-Shank Jig Saw Blade
This Bosch blade focuses on precision with a 24 TPI count and a design intended to minimize blade deflection during deep cuts. It’s suitable for both metal and sandwich materials that demand accuracy and clean edges. The wavy set and milled teeth help maintain control and reduce wandering, making it a reliable option for metal-focused DIY and professional projects alike.
50 Piece Contractor Jigsaw Blades Set with Storage Case
This mixed blades set includes metal-appropriate options such as T118A (thin metal) and T118B (medium metal) along with several wood-focused blades. High-carbon SK5 steel construction delivers wear resistance, while the set’s variety supports mixed-material projects. Proper lubrication is recommended when cutting metal to maximize blade life and performance.
Micro Traders 10pcs T136A JigSaw Blades
The Micro Traders T136A set uses high-speed steel for durable straight cuts. While designed for both wood and metal, these blades are noted for fast, straight cuts across a range of materials, including metal bars and iron plates. The 107 mm working length provides extended reach for deeper cuts in metal assemblies and framed pieces.
DEWALT Jigsaw Blades Set with Case, 14-Piece
The DEWALT 14-piece set focuses on compatibility with T-shank jig saws and supports both wood and metal cutting. This versatility makes it a practical choice for shops that frequently switch between materials, offering reliable performance across common metal-cutting tasks and composite workpieces.
20Pack T344D Long Jigsaw Blades Set
The T344D set is built for thick construction timber and softwood, with long blades designed for speed and long straight cuts. While primarily aimed at wood, the selection includes blades suitable for heavy-duty metal work in mixed-material applications, making it a solid complement for multi-material projects where long, straight cuts are required.
Bosch T718BF3 3-Piece 7 In. 14 TPI Flexible for Sandwich T-Shank
The Bosch T718BF3 features a 14 TPI tooth pattern and a bi-metal design for durability across metal and composite panels. Its extra-long length supports cutting through sandwich panels and other thick materials, with a focus on stable, clean finishes in demanding metal work scenarios.
Buying Guide: Key Purchase Considerations
When choosing long jigsaw blades for metal, consider material compatibility, tooth geometry, and blade construction. Bi-metal blades tend to offer a balance of durability and flexibility, while high-speed steel blades suit precise, fast cuts in thinner metal. Teethe per inch (TPI) affects cut speed, finish quality, and heat generation. For thick metal sections or composite panels, look for longer blades with strong shank mating and reduced deflection. If your projects involve mixed materials, a versatile mixed-blade set can reduce tool changes. Always check your jig saw’s compatibility with T-shank blades and the maximum blade length it supports.
Durability and wear resistance are critical. Blades made from high-carbon steel or SK5 steel with bi-metal construction typically last longer when cutting metal, especially across repeated passes. Proper lubrication and correct feed rate also help extend blade life and provide cleaner cuts. For occasional metal-only work, single-purpose blades can yield the best results, while for frequent multi-material tasks, a mixed-blade set maximizes value and reduces downtime.
