The DeWalt DW3700-5 U-shank reciprocating jig saw blade is a 6 TPI rough wood blade made from high-carbon steel with a reinforced tooth design for long life. Sold five blades per card. Universal U-shank shape fits older DeWalt, Bosch, Skil, Black & Decker, Craftsman, and Porter-Cable jig saws (note: most newer jig saws use a T-shank - check your saw before buying).

• Blade length: 4", 6 TPI
• Material: high-carbon steel
• Reinforced tooth design for extended cutting life
• Universal U-shank fits older DeWalt and most pre-T-shank jig saws
• 5 blades per pack (DW3700 blade in a 5-card)
• Reinforced tooth design holds an edge longer than economy blades in wood and composites.

Application: Use this 6 TPI rough wood blade for fast rough cuts in 2x lumber, plywood up to 1-1/2" thick, MDF, particleboard, and chair-back curves where speed matters more than finish. The 6 TPI tooth clears chips fast and rip-cuts cleanly along grain.

Tooth Pitch Selection: Match TPI to stock thickness - lower TPI cuts faster in thicker material, higher TPI prevents tooth-skip and tear-out in thin material. Within the U-shank family: 6 TPI (DW3700) for 2x wood and thick plywood, 14 TPI (DW3724) for 1/16-1/8" metal, 24 TPI (DW3726) for sheet metal 22-16 ga, 36 TPI (DW3728) for very thin sheet 24 ga and lighter. Keep at least 3 teeth in the cut at all times.

Cutting Tip: Let the blade do the work - heavy feed pressure breaks teeth and burns the cut. For metal, apply a few drops of cutting fluid and use a low blade speed; for wood, run the saw at full speed and use a steady forward feed. Replace blades at the first sign of edge dulling - a dull jig saw blade wanders off the line and burns the work.
