Dewalt DW3174 Circular Saw Blade 7-1/4 in 20T

Product Description

The DEWALT DW3174 is a 7-1/4 inch, 20-tooth circular saw blade engineered for cutting pressure treated lumber and wet wood on construction jobsites. The 20-tooth configuration is optimized for fast, aggressive rip and crosscut performance through dense, moisture-laden material that dulls standard blades quickly. At 0.55 pounds, the blade is lightweight enough for repeated blade changes without fatigue. Licensed contractors, framers, and construction carpenters reach for this blade when working with ACQ or CA-treated deck lumber, green framing stock, and other wet-condition wood materials where blade corrosion and binding are common concerns.

This blade is suited for residential and light commercial construction applications where pressure treated or wet lumber is the primary cutting material. Typical install scenarios include deck framing, ground-contact structural work, and rough framing in wet conditions. The 7-1/4 inch diameter matches the most common worm-drive and sidewinder circular saws used in the field, making it a direct drop-in for daily production cutting tasks.

Installation Notes

Blade installation and changes must be performed by a qualified tradesperson with the saw unplugged or the battery pack removed before any blade work begins. Confirm the arbor diameter of the saw matches the blade arbor before mounting. Follow the saw manufacturer torque guidance for the arbor nut and ensure the blade guard is fully functional before resuming cuts. Always wear appropriate PPE, including eye and hearing protection, when operating circular saws.
