Diablo Steel Demon Cermet II Saw Blade for Thick Metal – 8in, 42TCG Teeth, 5/8in Arbor, 0-degree Hook, .075 Kerf, D0842CF

Engineered for tough metal cutting

Diablo's Steel Demon Cermet II saw blade is built for thick metal and stainless steel, delivering crisp, burr-free results with less heat buildup. Designed for cordless or corded circular saws, it features an 8-inch diameter, 42 TCG teeth, a 5/8-inch arbor, a precise .075-inch kerf, and a 0-degree hook angle to help you maintain control and accuracy at speed, with a maximum of 4300 RPM.

Key benefits include extended blade life, cooler operation, and faster cutting performance, all while reducing sparks and dust. The Cermet II teeth fuse ceramic and metallic materials to resist wear under demanding cuts, offering up to 25x longer life than standard grinding discs and up to 10x faster cuts in suitable metal-cutting tasks.

Perma-SHIELD coating protects against gumming, rust, and corrosion, helping the blade stand up to humid or damp environments. The laser-cut stabilizer vents minimize noise and vibration, keeping temperatures steady and cuts accurate through long sessions.

Two practical bullet lists below summarize what you gain on the job. The first focuses on material performance; the second highlights applications and usage scenarios.

• Cermet II teeth provide high heat tolerance and increased hardness for wear resistance and longer life (vs standard grinding discs).
• Up to 50x cooler cuts, reducing heat buildup that can discolor steel and degrade performance.
• Perma-SHIELD coating lowers gumming, rust, and corrosion for extended blade life in challenging environments.
• Advanced Laser Cut Stabilizer Vents trap noise and vibration, aiding straight, accurate cuts while keeping the blade cooler.
• Triple Chip Grind and a one-blade solution enable smoother cuts with fewer burrs in metal and stainless steel.
• Productivity gains come from faster cuts, longer blade life, and smoother operation with less downtime.

What you can cut

• Steel studs and channels from 1/16 to 1/4 inch wall thickness
• Angle iron, flat bar, channel, and EMT conduit
• Thick metal sheets where burr-free edges matter

Note: Always follow tool and blade safety guidelines and match to your saw’s RPM rating to unlock the blade's potential without overloading the motor.
