Prune trees and shrubs quickly or power through pressure-treated lumber， wet wood， composite board， and plywood with SKIL’s The UGLY 9-Inch 5-TPI Wood Cutting Reciprocating Saw Blade. This 9-inch reciprocating saw blade features fleam-ground teeth that cut in both forward and reverse directions for twice the cutting efficiency. The blade’s high-carbon steel cutting edge retains sharpness to keep your cuts straight with less vibration and superior control. Its 9-inch length makes it optimal for cutting tree branches and shrubs， or 4x4 and 6x6 wood posts. The one-piece design allows the saw blade to be rigid yet flexible for stronger cutting， with five teeth per inch well-fastened to the body of the blade for fast cutting. It’s an ideal reciprocating saw blade for pruning with the SKIL PWR CORE 20™ 20V Reciprocating Saw but is designed to fit most reciprocating saws.
