WORKPRO Bi-Metal Set For Metal And Wood
The WORKPRO 10-piece bi-metal set combines M2/M42 HSS with a D6A bi-metal alliance for enhanced durability and heat resistance. Coated to resist rust, these blades are designed for high-stress metal cuts and demolitions. With the inclusion of 6/10/14/18 TPI blades, users gain flexibility: lower TPI for faster metal cutting and higher TPI for smoother finishes when needed. The set’s universal compatibility means most standard reciprocating saws in the market will accept these blades, with a caution to avoid Black+Decker Scorpion models. Ideal for mixed-use projects that involve metal demolition and occasional wood cuts.
Key features include: long blade life from advanced bi-metal construction, heat-treated coating protection, and a TPI range that supports both aggressive metal cutting and cleaner finishes on thicker materials. This makes the WORKPRO set a practical starter choice for DIYers tackling metal and occasional wood tasks in UK workshops.
Starrett B618-5 150 mm Bi-Metal Blade
The Starrett B618-5 150 mm blade uses a straight-cut bi-metal design, optimized for harder metal cuts where the tip may experience forced entry. Its 18 TPI configuration is suited to mid-thickness metal sections and sheet metal, delivering steadier progress and more predictable finishes. The unified shank design ensures compatibility across most cordless reciprocating saws, providing reliable grip and stability during aggressive cutting. This blade is particularly suitable for metal sheet and sections where precision and a clean edge are important.
Starrett promotes 3X power improvements with their bi-metal lineup, extending blade life and cutting rates relative to standard blades. The combination of a proven straight-cut geometry and a sturdy shank makes this option a solid choice for serious metal work in construction and renovation projects across the UK.
Saxton 200mm R825BF Heavy-Duty Metal Blade
The Saxton R825BF offers a 200 mm length with 14 teeth per inch, milled with a wavy set for robust, fast cutting through medium-thickness metal sheets and profiles. Made from bi-metal material, these blades are designed to handle 2–8 mm metal sheets and solid pipes up to 150 mm in diameter. The longer blade body can increase cutting depth and reduce blade twisting under load, while the wavy set helps to manage heat and debris during heavy-duty demolition tasks. This blade is a practical choice for builders who frequently cut metal in a workshop or on-site setting.
With compatibility across Bosch, Dewalt, Makita and other major brands, the R825BF focuses on delivering steady performance and progress, making it suitable for contractors and DIY enthusiasts who want dependable mid-range metal-cutting capability without premium pricing.
Bosch S1155 CHC Thick Tough Metal Blade
The Bosch Professional S1155 CHC is designed for tough steel and cast iron, featuring carbide-technology for extended blade life. Its 225 mm length provides deep cutting capacity, while its carbide-enhanced construction aims to endure tougher materials more reliably than standard HSS blades. Bosch emphasizes long-lasting durability and compatibility with all S-shank reciprocating saws, making this blade a strong long-term addition for tradespeople tackling heavy metal demolition or emergency extrication tasks. The design prioritizes longevity and steadier cuts under challenging conditions.
Starrett B624-5 150 mm Metal Blade
The Starrett B624-5 blade pack features 24 TPI straight-cut blades in a 150 mm length, designed for precise metal cutting with a steady edge finish. Like the B618 series, these blades employ bi-metal construction to balance life and stiffness, allowing efficient cutting of metal sheets and small profiles. The 24 TPI configuration is well-suited to thinner metal work or finishing passes where a smooth edge is preferred. As with Starrett’s other bi-metal blades, the shank is designed for broad compatibility with most corded or cordless reciprocating saws, ensuring easy integration into an existing toolset.
Buying Guide
- Blade material: Bi-metal blades combine high-speed steel teeth with a flexible steel body for longer life in metal cutting. They resist heat buildup and are less prone to snapping under load.
- Teeth per inch (TPI): Lower TPI (e.g., 6–10) cuts faster but rougher; higher TPI (e.g., 18–24) yields cleaner edges but slower progress. For metal, a mid to high TPI is often preferred for cleaner finishes on thinner sections, while lower TPI is useful for demolition work on thicker sections.
- Blade length: Longer blades reach deeper into materials but can bend if not braced properly. Choose length based on material thickness and cutting depth requirements.
- Shank compatibility: Most blades use standard universal shanks; verify fit with your saw’s model and brand. Some blades are not compatible with specific models (e.g., certain Black+Decker Scorpions).
- Durability features: Heat-treated coatings, rust-resistant finishes, and carbide-tipped teeth offer extended life when cutting tough metals or performing repetitive cuts.
- Cut type: Straight-cut blades work well for metal sheets and profiles, while wavy or milled edges can help with debris clearance and smoother finishes on certain materials.
- Application scope: For mixed tasks (metal, wood), consider sets with a range of TPIs to cover rough demolition and finishing passes without swapping blades often.
