Dewalt DWA7747 14 Inches 66T Metal Cutting Saw Blade

Product Description

The DEWALT DWA7747 is a 14-inch, 66-tooth circular saw blade engineered for cutting ferrous metals and heavy-gauge steel. The blade is constructed with 12% titanium carbide tips brazed using a tri-foil process, which reinforces each tooth tip for extended service life under demanding conditions. Modified ATB (alternate top bevel) tooth geometry produces clean, burr-free cuts, reducing secondary finishing work. Built-in expansion slots dissipate heat during high-load cuts, helping the blade maintain dimensional stability and prolonging usable life. Licensed HVAC, mechanical, and metalworking professionals will find this blade suited to repetitive steel cutting tasks on the job site.

The DWA7747 is designed for use in applications involving heavy-gauge steel and ferrous metal cutting. It is appropriate for both commercial and industrial job sites where consistent, clean cuts through structural steel, conduit, angle iron, and similar ferrous materials are required. The stiff plate design minimizes run-out during cutting, improving cut accuracy and blade longevity in high-cycle use.

Key Features

• 12% titanium carbide tooth tips for extended durability in ferrous metal cutting
• Tri-foil braze process reinforces each tooth tip against impact and heat stress
• Modified ATB tooth geometry delivers clean, burr-free cuts
• Expansion slots dissipate heat to extend blade life under continuous use
• Stiff plate design minimizes run-out for accurate, repeatable cuts
• Precise tip placement supports longer blade life and cut accuracy

Compatibility

Designed as an OEM-specification 14-inch metal cutting saw blade compatible with 14-inch chop saws and circular saws rated for ferrous metal cutting applications.

Installation Notes

Installation should be performed by a qualified tradesperson following the saw manufacturer guidelines. Disconnect power and verify the saw is fully de-energized before mounting or removing the blade. Confirm the blade arbor size, rotation direction arrow, and maximum RPM rating match the host saw before operation. Eye protection, hearing protection, and appropriate PPE are required when cutting ferrous metal.
