7-1/4 Inch Metal Cutting Circular Saw Blade 48T Cermet,5/8" Arbor

The HardWinTools 7-1/4 Inch Metal Cutting Circular Saw Blade is built for metal fabricators and DIY users who need clean, reliable cuts through tough structural metals. Engineered with 48 cermet carbide-tipped teeth, this blade tackles heavy materials such as rebar, angle iron, channel steel, round bars, and metal tubing without the excessive heat and mess of abrasive wheels.

A major focus of this blade is clean cutting and thermal management. The ceramic alloy tooth technology lowers cutting temperatures and minimizes sparks. This helps protect your workpiece from heat discoloration while delivering smoother edges that require significantly less post-processing work. The ultra-thin kerf profile also ensures that you lose less material per pass, keeping cuts economical and fast.

Durability comes from a laser-cut high-precision steel core combined with high-hardness teeth and a protective anti-rust, anti-stick coating. This construction supports demanding continuous cutting without sticking or premature wear. Built-in noise-reduction technology and tuned tooth geometry work together to keep vibration down for steadier, more accurate passes.

When it comes to compatibility, the standard 5/8-inch arbor fits most corded and cordless circular saws, including Diablo tools. For the cleanest cuts and longest life, the manufacturer does recommend pairing the blade with dedicated professional metal cutting equipment rather than forcing it through standard high-speed wood saws.

Verdict: This blade is a solid choice for anyone cutting rebar, channel steel, or metal pipe who wants low-spark operation and smooth edges. It delivers cleaner cuts and less waste for both workshop fabrication and home projects.

• Blade Diameter: 7-1/4 inches
• Tooth Count: 48 teeth
• Tooth Material: Cermet carbide / ceramic alloy
• Arbor Size: 5/8 inch
• Blade Core: Laser-cut high-precision steel
• Coating: Anti-rust and anti-stick
• Target Materials: Rebar, channel steel, angle iron, metal pipes, round bars

A great fit if you:

• Cut steel pipe, rebar, angle iron, or channel steel regularly.
• Want clean metal edges with minimal sparks and no heat discoloration.
• Need a 7-1/4 inch blade with a standard 5/8-inch arbor for your circular saw.
• Prefer thin-kerf blades that save material during fabrication projects.

Consider something else if you:

• Need a blade with an arbor size other than 5/8 inch.
• Only cut wood, plastic, or non-ferrous soft metals.

What types of metal can this blade cut?
It is engineered to cut various structural steels, including rebar, channel steel, angle iron, round bars, and metal pipes.

Will this blade fit my circular saw?
Yes, as long as your saw uses a 7-1/4 inch diameter blade with a standard 5/8-inch arbor. It is compatible with mainstream corded and cordless saws.

How does it keep metal from discoloring?
The blade uses ceramic alloy tooth technology designed to lower cutting temperatures and minimize spark production, which prevents heat-related material discoloration.

Does it require special tools to run?
While it fits mainstream circular saws, pairing the blade with professional metal cutting equipment is recommended for optimal performance.
