Crescent Metal Circular Saw Blade Set CSBMM-748 7-1/4 Inch 5 Pack Tool (48T Cermet SteelSlicer Thin Kerf ActiveShield Strut Rod Iron Slicing)

Crescent CSBMM-748 SteelSlicer™ 7-1/4" 48-Tooth Medium Metal Circular Saw Blades (5-Pack)

The Crescent CSBMM-748 SteelSlicer™ 7-1/4-inch 48-tooth circular saw blade slices structural angle iron, sections galvanized strut channels, trims all-thread rods, and cuts medium-gauge carbon steel plate without sparking or creating rough edge burrs. Engineered with Heat Defense™ premium cermet teeth and an ultra-thin kerf profile that delivers up to 20X longer cutting life and 40% cooler cutting temperatures, this 5-pack of metalworking discs operates seamlessly across cordless and corded metal cutting circular saws. Featuring an ActiveShield™ non-stick protective barrier that prevents frictional gumming and corrosion, combined with laser-cut harmonic vibration and expansion slots for true perimeter balance, it equips commercial electricians, mechanical pipefitters, and structural ironworkers with straight, burr-free, cool-to-the-touch cuts on demanding metal fabrication sites.

Best Used For:

• Galvanized Strut and Conduit Sizing: Sectioning 1-5/8-inch Unistrut channels, heavy-gauge steel raceways, and EMT electrical tubing with clean, burr-free factory square ends.
• Threaded Rod and Hardware Modification: Cutting 3/8-inch to 3/4-inch zinc-plated steel all-thread hanging rods quickly without ruining the lead threads or requiring thread chasing.
• Structural Angle Iron and Steel Tube Slicing: Slicing medium-gauge structural angle iron, rectangular box tubing, and flat mild steel plates with minimal heat transfer.

Key Performance & Safety Features

• Heat Defense™ Premium Cermet Teeth: Advanced ceramic-metal composite formulation withstands extreme thermal shock and delivers up to 20 times the operational lifespan of standard carbide.
• 40% Cooler Cutting Geometry: Optimized tooth angles dissipate friction heat rapidly to produce cool-to-the-touch cuts that eliminate metal discoloration and post-cut rework.
• ActiveShield™ Protective Non-Stick Finish: Thermally bonded barrier shields the blade body from friction heat, metal chip gumming, and atmospheric corrosion.
• Thin Kerf Burr-Free Design: Slim cutting profile removes minimal material stock, decreases motor resistance on cordless saws, and delivers ultra-clean edge finishes.
• Laser-Cut Harmonic Vibration Slots: Engineered body expansion slots absorb rotational vibration to eliminate blade chatter and enhance cutting accuracy.
• Corded and Cordless Saw Optimization: Low-drag tooth matrix maximizes battery efficiency on 18V, 20V, and 36V metal cutting saws while handling continuous corded shop use.

Pro-Tip: When cutting structural angle iron or thick Unistrut channels with a circular saw, maintain a firm, constant forward feed rate without pausing; steady forward movement allows the 48 cermet teeth to shave chips smoothly, preventing heat glazing and preserving razor sharpness.
