Morse Master Cobalt Bi-Metal Portable Band Saw Blade
Brand: MK Morse
Features: Made in the USA, Shock resistant cutting edge for cutting any machinable metal, Variable tooth pitch for broader range of applications
These cobalt-bimetal blades offer enhanced abrasion resistance and heat tolerance, making them suitable for repetitive cuts in diverse metals. Their shock-resistant edge helps minimize tooth chipping and blade life loss in tougher materials. The variable tooth pitch improves performance across a broad set of metals, reducing vibration and delivering cleaner cuts for both roughing and finishing passes. Ideal for portable band saw use where versatility and durability are priorities.
FOXBC 64-1/2″ Bi-Metal M42 Blade, 24 TPI
Brand: FOXBC
Features: 64-1/2″ x 1/2″ x .02″ x 24 TPI Bi-Metal M42 Blade; Compatible with WEN 3970 and other common models; Suitable for mild steel, aluminum, angle iron, bronze, copper, galvanized pipe, stainless steels, and tougher materials at slow speeds
Designed for larger, stationary band saws, this blade blends M42 steel with a high-hardness tooth edge to balance fast cutting with extended life. The 24 TPI configuration favors clean, precise cuts in soft to moderately hard metals, while the bi-metal construction resists heat buildup and tooth wear. It’s a strong option for shops cutting a variety of metals on longer runs or in job-site environments.
Imachinist M42 93″ Bi-Metal Blade
Brand: Imachinist
Features: 93″ long, 3/4″ wide, 0.035″ thick, 10-14 TPI; Bi-metal construction using M42 grade steel; Designed for cutting soft ferrous metals and profiles like tubes, pipes, and thin-walled sections
As a long, high-width blade, this option suits deep-cut needs and thicker stock while maintaining flexibility. The 10-14 TPI range offers a good balance between aggressive material removal and control, making it appropriate for thin-walled profiles and soft ferrous metals. It is best used on heavier-duty machines that can maintain tension and straight cuts even over long runs.
Bosch BS9312-18MA Metal-Cutting Blade
Brand: Bosch
Features: Engineered for soft-metal cutting (aluminum, copper, bronze); Durable blade design with heat resistance; Premium materials to resist heat buildup and extend blade life
Bosch’s stationary blade focuses on soft-metal applications with geometry optimized for reduced heat build-up. The alloy and manufacturing processes are designed to promote longevity under continuous metal-cutting tasks, while maintaining consistent cuts. This blade is well-suited for hobbyists and light commercial work that frequently targets aluminum and similar metals.
FOXBC 59-1/2″ Bi-Metal Blade, 24 TPI
Brand: FOXBC
Features: 59-1/2″ x 1/2″ x .025″ x 24 TPI, Bi-Metal M42 Blade; Suitable for mild steel, aluminum, copper, galvanized pipe, and tougher steels at slow speed; also handles some plastics and wood-based projects
With a shorter length than the 64-1/2″ option, this blade is ideal for mid-size bandsaws and projects where space limits blade length. The 0.025″ thickness and 24 TPI enable clean cuts in common metals while preserving blade integrity in longer runs. It balances versatility with cutting performance in mixed-material shops.
Milwaukee Alloy Steel 18 TPI Sub-Compact Blade
Brand: Milwaukee
Features: Matrix II high-speed steel teeth for durability; Alloy backing steel extends blade life; Precision-formed teeth enable fast, clean cuts
This three-pack blade series prioritizes compact band saws used for metal fabrication. The Matrix II steel teeth reduce wear under repeated cycles, while the alloy backing supports blade rigidity through challenging materials. It’s a practical choice for smaller machines performing precise cuts on metal stock, with an emphasis on longevity and reliable performance.
POWERTEC 93-1/2 Inch Bi-Metal Blade, 14 TPI
Brand: POWERTEC
Features: 1 blade per pack; Designed for cutting soft metal including aluminum, copper, lead, zinc and tin; 14 TPI with raker-set teeth for even cutting
POWERTEC’s blade is aimed at soft metals and general-purpose metalworking. The raker-set tooth arrangement helps clear chips efficiently, which is beneficial for thinner stock and more delicate cuts. It pairs well with universal metalworking tasks and hobbyist projects where easy sharpening and predictable performance matter.
Bosch BS6412-24M 64-1/2″ 24 TPI Blade
Brand: Bosch
Features: Metal-cutting specialization; Premium materials resist heat buildup; Optimized tooth geometry for best performance
Bosch’s 64-1/2″ blade emphasizes stable performance in metal-cutting tasks with a tooth geometry designed to optimize cutting efficiency and heat management. It is a solid option for long runs and repeated cuts in ferrous and non-ferrous metals, balancing durability with consistent cutting action in professional workshops.
Buying Guide: Key Considerations When Choosing Band Saw Blades For Metal
- Tooth configuration and pitch: Higher tooth counts (e.g., 24 TPI) yield smoother cuts on thin or softer metals, while lower counts remove material faster on thicker or harder stock. Bi-metal blades help resist heat buildup and wear.
- Blade material: M42 and cobalt-infused bi-metals provide improved wear resistance and heat tolerance for metalworking. Aluminum-appropriate blades focus on reducing heat buildup to protect the blade.
- Blade width and thickness: Wider blades offer more stability for straight cuts in larger stock, while thinner blades reduce resistance in tight radii and thin-walled sections.
- Machine compatibility: Ensure blade length and width match your saw’s capacity, whether portable or stationary. Some blades are designed for specific models or brand families.
- Application range: For mild steels and non-ferrous metals, softer-metal blades with optimized tooth geometry perform well. For stainless or harder alloys, select blades with higher alloy content and tougher steels.
- Heat management: Blades with heat-resistant materials or coatings help prevent tooth deformation and extending blade life during extended cuts.
- Maintenance and replacement: Consider availability in multi-packs and compatibility with common stock sizes to minimize downtime.
