Diablo Steel Demon Cermet II 6-1/2 in. x 48T Circular Saw Blade for Medium Metal brings a new level of productivity to cutting steel studs, angle iron, EMT conduit, flat bar, channel, and threaded rod with either a cordless or corded circular saw. Engineered by Diablo with proprietary Cermet II tooth technology - a ceramic and metallic compound - this blade delivers up to 25X longer life, 50X cooler cuts, and 10X faster cuts compared to standard grinding discs, making it a true one-blade solution for demanding metal fabrication and construction work. Whether you are cutting stainless steel or mild steel profiles on the jobsite, this blade produces precise, burr-free results with dramatically fewer sparks and less airborne debris than conventional abrasive cutting methods.

Key Features

• Cermet II (Ceramic and Metallic) teeth - deliver high heat tolerance and increased hardness for superior wear resistance, meaning fewer blade changes and up to 25X longer cutting life versus standard grinding discs so you stay productive longer on the job.
• Up to 50X cooler cuts - grinding discs raise steel temperature by up to 500 deg. Fahrenheit and can permanently discolor the metal; this blade keeps cuts cooler to preserve material integrity and finish quality.
• Up to 10X faster cuts - results in up to 60 seconds saved per cut in both metals and stainless steels versus standard grinding discs, dramatically improving throughput on high-volume cutting tasks.
• Triple Chip Cutting action - reduces sparks during cutting, which lowers the possibility of needing "hot" permits and increases safety on the jobsite.
• Optimized blade design reduces wandering and deflection - creates precise cuts that require virtually no re-work, saving time and material costs.
• Advanced Laser Cut Stabilizer Vents - trap noise and vibration for maximum stability and keep the blade cool, resulting in straight, accurate cuts even in extended use.
• Tri-Metal Shock Resistant Brazing - a three-metal brazing system allows the Cermet II teeth to withstand extreme impact for maximum durability when cutting hard metal profiles.
• Laser Cut Thin Kerf Design (.061 in. kerf) - provides less resistance and heat build-up for easier cutting, greater accuracy, and long cutting life whether used in cordless or corded saws.
• Perma-SHIELD coating - protects the blade body against gumming and corrosion by resisting heat build-up, extending the usable life of the blade.
• Laser Cut Arbor (5/8 in.) - reduces vibration and premature wear for accurate blade rotation during use, improving cut quality and blade longevity.
• Controlled cutting action produces larger chip sizes - generates less dust and airborne contaminates compared to grinding discs, creating a healthier and cleaner work environment.
• Cuts both metals and stainless steels - eliminates the need for individually dedicated saw blades, offering a versatile one-blade solution for mixed-material metal cutting applications.

Why This Product

• For trades workers cutting steel studs, EMT conduit, angle iron, and threaded rod daily, this blade replaces the grinding disc workflow entirely - delivering faster cuts, cooler results, and a finish that requires virtually no re-work, all from a standard circular saw or trim saw.
• The Cermet II tooth compound offers a measurable performance advantage in heat tolerance and hardness over conventional abrasive discs, which means material discoloration and heat-related warping are dramatically reduced when cutting stainless steel and structural steel alike.
• The Triple Chip Grind and reduced-spark cutting action help minimize the need for hot work permits in fire-sensitive environments - a practical advantage on commercial construction sites with strict safety requirements.
• Compatible with corded circular saws, trim saws, and cordless circular saws, this blade adapts to the tools already on the job, making it a flexible upgrade for metal cutting without requiring specialized equipment.

Frequently Asked Questions

What types of metal can this blade cut?

This blade is designed for cutting steel studs and channel, angle iron, EMT conduit, flat bar, and threaded rod. It handles both standard metals and stainless steels, eliminating the need for separately dedicated blades for each material type. Refer to the thickness and diameter usage ranges in the Specifications section to ensure the material you are cutting falls within the supported capacity.

Can this blade be used with a cordless circular saw?

Yes. The Laser Cut Thin Kerf Design reduces resistance and heat build-up, making this blade well suited for use in both cordless and corded circular saws, as well as trim saws. The maximum rated speed is 5800 RPM - always confirm your saw operates within this limit before use.

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

According to Diablo's data, this blade delivers up to 25X longer life, 50X cooler cuts, and 10X faster cuts compared to standard grinding discs. Grinding discs can raise steel temperature by up to 500 deg. Fahrenheit and may permanently discolor the metal. This blade's controlled cutting action also produces larger chip sizes, generating less dust and airborne contaminates than abrasive disc cutting.

What is the hook angle and why does it matter for metal cutting?

This blade features a 0 deg. hook angle, which is intentionally designed for metal cutting applications. A neutral hook angle provides a controlled, stable cutting action that reduces the risk of blade grab or aggressive feed into hard materials, helping produce precise, burr-free cuts with less deflection and wandering.
