Dewalt DW3705H Jig Saw Blade 4in 8TPI Hcs U-shank 5 Pack

Product Description

The DEWALT DW3705H is a high-carbon steel (HCS) jig saw blade designed for cutting aluminum and fiberglass. At 4 inches in length with an 8 TPI (teeth per inch) configuration, it delivers controlled, clean cuts through non-ferrous metals and composite materials. The U-shank design provides a universal fit across a wide range of jig saws. Sold in a 5-pack, this blade is a practical choice for HVAC technicians, electricians, and general tradespeople who regularly cut aluminum sheet stock, fiberglass duct board, or composite panels on the job.

This blade is well suited for light-metal fabrication and fiberglass panel work in both residential and commercial settings. Common applications include cutting aluminum flashing, fiberglass reinforced panels, and similar non-ferrous or composite materials. The 8 TPI tooth count balances cut speed with surface finish, making it appropriate for trade applications where clean edges matter. The 5-pack format reduces downtime by keeping spares on hand during extended work.
