For use with jigsaws with T-Shank clamping systems. The T 308 BF Extra-Clean for Hard Wood Jigsaw Blade delivers extra-clean straight cuts in wood. Its precision-ground teeth with taper-ground body cut cleanly. Additionally, two rows of teeth arranged at different angles provide tear-free cuts at the top and bottom surfaces. Made from BIM (bi-metal), its fully hardened HSS (high-speed steel) tooth strip is bonded with its highly elastic HCS (high carbon steel) body, making the blade appropriate for cutting hard materials such as hardwood and abrasive woodworking materials. It is equipped with a 2.2XC tooth geometry, fine tooth pitch (2.2 mm) and long-length blade (117 mm) for cutting solid wooden materials with 5-50 mm thickness.
