Morse Master Cobalt Bi-Metal Portable Band Saw Blade

The Morse Master blade from MK Morse is a cobalt bi-metal blade designed for portable band saws. It features a shock‑resistant cutting edge intended to handle machinable metals with a durable lifespan. The variable tooth pitch expands its applicability, offering a broader range of cuts—from soft metals to harder alloys—while maintaining a balance between aggressive cutting and controlled finish. Ideal for users who switch between metal types and require reliable performance in varied workshop tasks.
FOXBC 64-1/2″ Bi-Metal M42 Bandsaw Blade

FOXBC offers a long 64 1/2 inch blade with 24 TPI, built as a bi-metal M42 blade. It’s compatible with multiple popular saws including Harbor Freight and JET models, and is designed to cut mild steel, aluminum, bronze, and even harder materials at slower speeds. The blade’s durability makes it a strong choice for shops handling a mix of metal types, while the 64‑inch length supports larger workpieces and versatile setups.
Imachinist S933414 M42 93″ Bi-Metal Blade

The Imachinist S933414 blade is a long, heavy‑duty M42 bi‑metal blade measuring 93 inches in length and 3/4 inch in width. With a 10–14 TPI range and a 0.035 inch thickness, it’s optimized for cutting soft ferrous metals and profiles like pipes, tubes, and profiles. Its bi-metal construction provides a balance of wear resistance and toughness for extended blade life in demanding metal‑cutting applications.
BOSCH BS9312-18MA 93-1/2 in. Blade

The Bosch BS9312-18MA is engineered for metal cutting with a durable design and heat‑resistant properties. This 93‑inch blade features premium materials and an optimized tooth geometry tailored for metal applications, delivering reliable performance on soft metals to tougher alloys. It’s well suited for stationary band saws used in metal fabrication and workshop environments that demand longevity and consistent cuts.
Milwaukee 48-39-0631 30-9/16″ Extreme Thick Metal Blade

The Milwaukee 30-9/16 inch blade targets extreme thick metal with a 12/14 TPI configuration. It’s part of a three‑pack designed for extended projects where aggressive cutting is required on stainless steel and other hard metals. The blade’s design emphasizes longevity and compatibility with compact, portable band saw models, delivering solid performance for heavy gauge material and demanding cuts.
Buying Guide
Key considerations when selecting a band saw blade for metal include blade material, length, width, thickness, and tooth configuration. Bi‑metal blades (often M42 or cobalt enhanced) offer a good balance between wear resistance and blade toughness, ideal for mixed metals. Longer blades enable cutting larger workpieces and provide more versatility, especially on stationary saws. Tooth pitch (TPI) affects cutting speed, finish, and heat generation: higher TPI produces smoother cuts in softer metals; lower TPI enables faster removal in thicker or tougher stock. For portable saws, compatibility with common sizes such as 44–64 inches is essential. Always verify your saw’s wheel width and blade width requirements to avoid binding or derailment. Heat buildup resistance is important for extended blade life in heavy cutting. Consider whether you need a blade optimized for stainless steel, aluminum, or hardened alloys, and whether a mixed batch (as in a 3‑pack) provides cost efficiency for ongoing projects.
Comparing the five highlighted options shows a spectrum of use cases:
– Short, portable workpieces benefit from the Morse Master’s cobalt bi‑metal edge and variable pitch for flexibility.
– The FOXBC blade emphasizes compatibility across many saw models with a robust 64 1/2″ length and 24 TPI for detailed cuts on metal sheets and bars.
– Imachinist’s 93″ M42 blade suits long stock and profiles, offering a solid balance of speed and durability for thicker cuts.
– Bosch’s BS9312-18MA focuses on stationary metal cutting with an emphasis on heat resistance and optimized geometry.
– Milwaukee’s extreme thick metal blade is designed for thick gauge materials and frequent blade changes, prioritizing longevity in tough jobs.
Choosing among these depends on your specific saw type (portable vs. stationary), material mix, and the required balance of speed and finish.
