The Exchange-A-Blade steel blade delivers a cost-effective metal roofing solution with 72 teeth engineered for thin gauge metals, built for contractors cutting sheet metal daily.
This blade suits contractors who need clean cuts on steel roofing and siding up to 18 gauge without the upfront cost of carbide. The unconditional guarantee backs it for high-volume metal roofing crews working Montana’s construction season.
The 72 steel teeth in ATBF (Alternate Top Bevel Flat) configuration target ferrous and non-ferrous metals. Steel teeth work differently than carbide: they’re softer but can handle the flex and heat of cutting thin sheet metal without chipping.

The hard-bodied blade design improves performance in roofing applications. Designed for thin ferrous and non-ferrous metals, it handles the materials Montana contractors work with daily: standing seam panels, corrugated sheets, aluminum trim coil.
The industry standard Diablo D0770F Steel Demon uses 70 carbide teeth for longer lifespan but costs more. EAB’s professional-grade alternative (Item# 1017302) drops to 32 carbide teeth for heavier gauge steel studs and roofing up to .062 gauge. This 72-tooth steel blade fills the gap for high tooth count at lower initial cost.
Metal roofing dominates new construction and reroofing projects across Montana. Fire resistance matters in high-wildfire zones. Snow shedding prevents ice dams. The materials last 40-70 years versus 20-30 for architectural shingles.
This blade cuts steel roofing and siding up to 18 gauge, aluminum roofing and siding, and general sheet metal. That covers most residential metal roofing materials. The thin kerf design reduces material waste and requires less power from your saw: important when running corded tools off long extension cords or pushing battery saws to their limits.
This blade’s convenience for one-time DIY projects makes it practical for both contractors and homeowners, even with a shorter lifespan compared to carbide-tipped blades.
The Verdict
Worth it for metal roofing contractors who want an affordable alternative to carbide longevity. The 72 steel teeth handle ferrous and non-ferrous metals up to 18 gauge.
Not the blade for cutting heavy structural steel or maximizing blade longevity. But for contractors installing metal roofing day after day, the combination of adequate performance and low upfront cost makes sense.
EAB backs it with a straightforward policy: any dissatisfied customer can return products for replacement or refund. That confidence comes from understanding their market: contractors who need functional blades that perform well, not maximum possible blade life at premium cost.
