Morse Master Cobalt Bi-Metal Blade
The Morse Master blade from MK Morse is designed for tough metal cutting on portable bandsaws. It uses cobalt-enhanced cutting edges within a bi-metal construction to resist wear and breakage under vibration, supporting longer life in demanding shop environments. The 14/18 tooth pitch provides versatility across various machinable metals, enabling both rapid rough cuts and smoother finishes in one blade. It is manufactured in the USA, aligning with reliability expectations for professional use.
With a 44-7/8″ length, 1/2″ width, and a .020″ kerf, this blade fits common portable saws and minimizes material loss. The triple-pack format offers continuity for ongoing projects or multiple machines, reducing downtime between blade changes. This blade suits metal fabrication, plumbing, and light industrial tasks where consistent performance matters.
DEWALT 32-7/8-Inch 18 TPI Blade
DEWALT’s 32-7/8-Inch blade employs Matrix II high-speed steel designed to withstand heat and wear during metal cutting. The blade contains 8% cobalt content, contributing to added durability and wear resistance, while achieving Rc 65-67 tooth hardness. This combination supports longer blade life in heavy-duty portable saw tasks. The blade comes in a three-pack, offering value for frequent users who rely on consistent performance across multiple projects or machines.
Measuring 32-7/8 inches in length with a 1/2 inch width and .020 inch kerf, this blade is well-suited for compact portable bandsaws that still require robust metal-cutting capability. The 18 TPI provides a middle-ground balance between speed and cut quality for machinable metals.
DEWALT 44-7/8-Inch 24 TPI Blade
This DEWALT blade is tuned for finer cuts on thinner metal, featuring 24 TPI for smoother finishes. The Matrix II high-speed steel edge provides heat and wear resistance, while the 8% cobalt content boosts durability for repeated use. The hard-to-wear tooth profile (Rc 65-67) contributes to extended wear resistance, making it a strong option for precision tasks on portable bandsaws. The blade comes in a 3-pack, offering consistent availability for ongoing work.
The blade’s 44-7/8″ length and .020″ kerf maintain compatibility with standard portable saws designed for larger blades. Its higher TPI makes it suitable where finish quality matters as much as speed, such as cutting thinner metal stock, brackets, or small-diameter components.
Lenox 44-7/8-Inch 14 TPI Blade
Lenox’s 44-7/8″ blade features a 14 TPI configuration, striking a balance between rapid metal removal and edge durability. Built as a bi-metal blade with high-speed steel teeth, it resists shattering and bending, extending blade life in tough portable saw applications. This blade is well-suited for mid-range metal cutting tasks where robustness and reliability are essential. It is provided in a 5-pack, delivering substantial value for shops with frequent blade changes.
The blade’s dimensions—44-7/8″ in length, 1/2″ width, and .020″ kerf—fit most standard portable band saws. The 14 TPI teeth enable steady cutting performance with metal stock commonly encountered in fabrication, maintenance, and construction environments.
Milwaukee 18 TPI Sub-Compact Blade
Milwaukee’s sub-compact portable blade is designed for smaller, more maneuverable saws while delivering reliable performance. The 18 TPI tooth configuration supports balanced cutting speed and finish quality on a range of machinable metals. Matrix II high-speed steel teeth provide durability, and the alloy backing steel is intended to extend blade life under repeated use. This blade comes in a three-pack, offering cost-effective supply for busy shops that rely on portable saws for everyday work.
The blade is positioned for compact portable saws and is compatible with metal-cutting tasks that demand precision without sacrificing speed. The 18 TPI setup helps achieve clean cuts in a variety of metals and thicknesses commonly encountered in maintenance, fabrication, and industrial settings.
Buying Guide
Blade length, width, and kerf compatibility
Ensure the blade length matches your portable bandsaw. Common sizes include 32-7/8″ and 44-7/8″. Width is typically 1/2″ for standard blades, with a .020″ kerf offering a balance of material removal and blade durability. Some models provide “sub-compact” or non-standard lengths, so verify fit before purchasing a multi-pack.
TPI and tooth geometry
- Lower TPI (10-14) blades cut quickly but may leave rougher finishes on thicker stock.
- Mid-range TPI (18) provides a balance suitable for most machinable metals and general-purpose work.
- Higher TPI (24) yields finer finishes on thin metals but can slow cutting and increase wear on tough material.
- Tooth pitch also affects vibration and heat; variable pitch blades help reduce noise and wear on mixed material types.
Material and construction
- Bi-metal blades combine a flexible backing with a hardened edge for durability and resilience in portable use.
- Cobalt-enhanced blades add hardness and wear resistance, improving life when cutting harder metals.
- Matrix II high-speed steel teeth improve heat resistance and edge retention, extending blade life in demanding jobs.
Durability, life, and value
- Consider blade life when choosing between a 3-pack or 5-pack. Higher-quality blades may cost more upfront but save downtime and part wear over time.
- Shatter resistance and rigidity reduce the risk of blade damage on vibratory portable saws, improving safety and performance.
Compare the five options by aligning blade characteristics with your typical projects: bulk metal removal, precision cuts on stainless steel, or cutting thinner stock where finish quality matters. Checking compatibility with your saw model and following manufacturer tensioning and lubrication guidelines will maximize performance and blade life.
