Diablo Steel Demon Cermet II 8" x 42-Tooth Saw Blade for Thick Metal is engineered for professionals who demand fast, precise, and long-lasting metal cutting performance with a cordless or corded circular saw. Designed to cut through steel studs, angle iron, flat bar, channel, EMT conduit, and stainless steel, this circular saw blade replaces traditional grinding discs with a single versatile solution that delivers dramatically cooler, faster, and cleaner cuts through thick ferrous metals.

Key Features

• Cermet II (Ceramic and Metallic) teeth deliver high heat tolerance and increased hardness - providing up to 25X longer life versus standard grinding discs, meaning fewer blade changes and lower long-term cost
• Up to 50X cooler cuts compared to grinding discs - prevents the permanent discoloration and heat damage that grinding discs can cause by raising steel temperature by up to 500 deg. Fahrenheit
• Up to 10X faster cuts - saves up to 60 seconds per cut in both metals and stainless steels versus standard grinding discs, dramatically increasing jobsite productivity
• Triple Chip Grind (TCG) tooth geometry - reduces sparks and minimizes the possibility of needing "hot" permits on the jobsite
• Optimized blade design reduces wandering and deflection of metal - creates precise cuts that require virtually no re-work, saving time and material
• Advanced Laser Cut Stabilizer Vents trap noise and vibration - keep the blade cool for straight, accurate cuts over extended use
• Tri-Metal Shock Resistant Brazing - a three-metal brazing system allows Cermet II teeth to withstand extreme impact for maximum durability in demanding metal cutting applications
• Laser Cut Thin Kerf design at.075" - provides less resistance and heat build-up for ease of cut, accuracy, and long cutting life in both cordless and corded saws
• Perma-SHIELD coating resists heat build-up - protects the blade against gumming and corrosion for consistent performance cut after cut
• Laser Cut Arbor reduces vibration and premature wear - ensures accurate blade rotation and extended service life
• One-blade solution for metals and stainless steels - eliminates the need for individually dedicated saw blades, reducing tool inventory and cost
• Controlled cutting action produces larger chip sizes - generates less dust and fewer airborne contaminants for a cleaner, safer work environment

Why This Product

• Cuts thick steel and stainless steel in a single blade - handles studs and tubing with wall thickness from 1/16" (16 gauge) up to 1/4", plates and bars from 1/8" (11 gauge) up to 1/2", and rods from 1/4" up to 1 1/2" diameter, covering the widest range of thick metal cutting tasks without switching blades
• Replaces grinding discs with a faster, cooler, and longer-lasting alternative - up to 25X longer life and up to 10X faster cuts mean significantly lower cost per cut and more uptime on the job
• Produces burr-free, precise cuts with less sparks - reduces the need for secondary finishing work and lowers the risk of spark-related hazards compared to grinding disc use
• Compatible with low RPM metal saws up to 4300 RPM - purpose-built for the tool type most commonly used in metal fabrication and mechanical work, ensuring safe and optimal performance

Frequently Asked Questions

Can this blade cut stainless steel as well as mild steel?

Yes. The Cermet II teeth are formulated to cut through both standard metals and stainless steels, offering a one-blade solution that eliminates the need for individually dedicated saw blades for each material type.

What is the maximum material thickness this blade can handle?

For plates and bars, the maximum thickness is 1/2". For studs and tubing, the maximum wall thickness is 1/4". For rods, the maximum diameter is 1 1/2". Always verify your material falls within the specified range for safe and accurate cutting.

Why does the Triple Chip Grind design matter for indoor or permit-sensitive jobsites?

The Triple Chip Cutting action significantly reduces sparks compared to grinding discs. Fewer sparks mean a lower possibility of needing "hot" permits, making this blade better suited for work in occupied or sensitive environments.

What is the maximum RPM rating and which tools is this blade designed for?

This blade is rated for a maximum of 4300 RPM and is designed for use with low RPM metal saws. Always ensure your saw does not exceed the maximum RPM rating to maintain safe blade operation.
