For use with jigsaws with T-Shank clamping systems. The T 344 DF Speed for Hard Wood Jigsaw Blade delivers fast straight cuts in wood. Its sharp-ground, side-set teeth make fast cuts. Made from BIM (bi-metal), the blade's fully hardened HSS (high-speed steel) tooth strip is bonded with its highly elastic carbon steel body, making it appropriate for cutting hard materials such as hardwood and abrasive woodworking materials. This product's large tooth pitch (4 mm) and long length (152 mm) enable cuts in solid wooden materials with up to 100 mm thickness.
