Diablo D053830FMX 5-3/8 in. x 30-Tooth Metal Cutting Saw Blade

The Diablo D053830FMX 5-3/8 in. x 30-Tooth Metal Cutting Saw Blade is a compact circular saw blade built for cutting mild steel with cordless trim saws and arbor saws. This is a metal cutting circular saw blade designed for clean, fast cuts in mild steel stock. Model Number: D053830FMX. If you need a blade for steel studs, angle iron, channel, flat bar, EMT conduit, or threaded rod without the mess and short life of abrasive wheels, this is the kind of blade you look at first.

The core setup here is straightforward and useful: a 5-3/8 inch diameter, 30-tooth layout, carbide construction, and a triple chip grind tooth design made for metal cutting. In real use, that tooth pattern matters because it helps the blade leave cleaner, burr-free cuts with less cleanup afterward. The thin kerf also helps cordless saws stay productive by reducing the amount of material being removed on every pass, so the saw does not have to work as hard to get through the cut.

Diablo also built this blade around jobsite durability. The TiCo hi-density carbide is specifically aimed at mild steel applications and is claimed to deliver up to 40 times longer life than standard blades used for the same type of work. Tri-metal shock-resistant brazing helps the carbide tips handle impact better, which is a big deal when you are cutting material that can chatter, shift, or hit harder than wood ever will. That adds up to a blade that is not just sharper on day one, but one that is meant to hold up longer under real use.

For cut quality and blade control, Diablo adds laser-cut stabilizer vents to reduce noise and vibration while helping the blade stay cooler. That helps limit blade warp and keeps cuts more consistent, especially when you are making repeated cuts in metal studs or conduit. The non-stick Perma-Shield coating is there for the less glamorous but still important part of ownership: it helps resist gumming, rust, and corrosion, so the blade is easier to keep in service when it rides in a truck, gang box, or jobsite box between uses.

Compatibility is another strong point. The blade is optimized around a 20 mm arbor and includes three bushings so it can also fit 1/2 inch, 5/8 inch, and 10 mm arbor saws. It is specifically compatible with select Milwaukee, Bosch, Panasonic, Makita, Skil, and DeWalt cordless saws based on arbor size. That makes this a practical option for users running compact metal cutting or trim saw setups who need one blade that can move between platforms and saw models with the right arbor match.

This blade is best for contractors and serious DIY users doing light steel cutting where speed, edge quality, and battery efficiency matter. If you are a framer, electrician, HVAC installer, remodeler, or general contractor cutting thinner mild steel stock, this blade makes sense. It is intended for mild steels with up to 1/8 inch maximum wall thickness and for threaded rod up to 1 inch maximum diameter, so it is built for common jobsite metal work, not heavy plate or thick structural steel.
