The Diablo Steel Demon Cermet II 12-inch x 80-Tooth Circular Saw Blade for Thin Metal (D1280CF) delivers a revolutionary approach to metal cutting on the jobsite. Engineered by Diablo with exclusive Cermet II tooth technology - a ceramic and metallic compound - this blade is purpose-built for cutting steel tube, steel studs, angle iron, flat bar, channel, EMT conduit, threaded rod, and stainless steel using a low RPM metal saw. Whether you are tackling structural framing, mechanical installations, or fabrication work, this 12 in. blade replaces the need for standard grinding discs with a single, high-performance cutting solution that produces precise, burr-free results with dramatically less heat, fewer sparks, and significantly faster throughput.

Key Features

• Cermet II (Ceramic and Metallic) teeth - deliver high heat tolerance and increased hardness for superior wear resistance, fewer blade changes, and up to 25x longer cutting life versus standard grinding discs, reducing downtime and overall tooling cost.
• Up to 50x cooler cuts compared to grinding discs - grinding discs can raise steel temperature by up to 500 deg. Fahrenheit, permanently discoloring the material; this blade keeps temperatures low to preserve material integrity and finish quality.
• Up to 10x faster cuts than standard grinding discs - delivers maximum productivity and efficiency with cuts up to 60 seconds faster in both metals and stainless steels, keeping projects on schedule.
• Triple Chip Grind cutting action - reduces sparks during cutting, lowering the possibility of needing hot work permits on regulated jobsites and improving overall safety.
• Optimized blade geometry reduces wandering and deflection - produces precise cuts that require virtually no re-work, saving time and material on every cut.
• Advanced Laser Cut Stabilizer Vents - trap noise and vibration for maximum blade stability, keeping the blade cool during extended use for straight, accurate cuts throughout the workday.
• Tri-Metal Shock Resistant Brazing - a three-metal brazing system allows Cermet II teeth to withstand extreme impact, maximizing tooth retention and blade durability under demanding cutting conditions.
• Laser Cut Thin Kerf design at.083 in. - reduces resistance and heat build-up for easier cutting, greater accuracy, and extended cutting life in both cordless and corded saws.
• Perma-SHIELD non-stick coating - resists heat build-up and protects the blade body against gumming and corrosion, extending the usable life of the blade even in harsh environments.
• Laser Cut Arbor design - reduces vibration and premature wear during operation, ensuring accurate blade rotation and consistent cut quality over the life of the blade.
• One-blade solution for metals and stainless steels - eliminates the need for individually dedicated blades for different metal types, reducing tooling inventory and delivering unmatched jobsite value.
• Controlled cutting action produces larger chip sizes - generates less dust and fewer airborne contaminants compared to grinding discs, contributing to a cleaner and healthier work environment.

Why This Product

• For tradespeople cutting a wide range of thin metals - from EMT conduit and threaded rod to stainless steel plate and angle iron - this blade consolidates multiple dedicated blades into one, reducing cost and simplifying tool inventory without sacrificing cut quality.
• The Cermet II tooth formulation provides up to 25x longer life than standard grinding discs, meaning fewer blade changes per job and a lower total cost of ownership over the lifetime of the tool.
• With up to 50x cooler cuts, this blade prevents the heat-related discoloration and metallurgical damage that grinding discs cause, making it the right choice when material finish and structural integrity matter.
• The combination of Triple Chip Grind geometry, Laser Cut Stabilizer Vents, and Perma-SHIELD coating means this blade is engineered to perform in both corded and cordless low RPM metal saws, giving crews the flexibility to work in any jobsite environment.

Frequently Asked Questions

What types of metal can this blade cut?

This blade is designed to cut steel tube, steel studs, angle iron, flat bar, channel, EMT conduit, threaded rod, and stainless steel. It handles studs and tubing with wall thickness from 1/16 in. (16 gauge) to 1/4 in., plates and bars from 1/8 in. (11 gauge) to 1/2 in. thick, and rods from 1/4 in. to 1 1/2 in. in diameter. The ability to cut both standard metals and stainless steel makes it a versatile one-blade solution for a wide range of thin metal cutting tasks.

What is Cermet II technology and why does it matter for metal cutting?

Cermet II refers to a specially formulated ceramic and metallic tooth compound used in these Diablo Steel Demon blades. This material provides high heat tolerance and increased hardness compared to conventional tooth materials, resulting in superior wear resistance, fewer required blade changes, and up to 25x longer cutting life versus standard grinding discs. The result is a more efficient, productive, and cost-effective metal cutting solution for demanding jobsite use.

What saw is required to use this blade?

This blade is designed for use with a low RPM metal saw. It has a 12 in. diameter, a 1 in. arbor, and a maximum operating speed of 1800 RPM. It is compatible with both corded and cordless circular saws configured for low RPM metal cutting. Always verify your saw meets the maximum RPM rating before installing the blade.

How does this blade compare to a standard grinding disc for cutting thin metal?

Compared to standard grinding discs, this Diablo Steel Demon blade delivers up to 25x longer life, up to 50x cooler cuts - preventing the up-to-500 deg. Fahrenheit temperature increases that can permanently discolor steel - and up to 10x faster cuts, with individual cuts up to 60 seconds faster. The Triple Chip Grind also reduces sparks and produces larger chip sizes with less airborne dust, improving both safety and worksite cleanliness relative to grinding disc use.
