The T 101 BRF Clean for Hard Wood Jigsaw Blade delivers clean straight cuts in wood. Its precision-ground teeth with taper-ground body cut cleanly. Made from BIM (bi-metal), the blade's fully hardened HSS (high-speed steel) tooth strip is bonded with its highly elastic HCS (high carbon steel) body, making it appropriate for cutting hard materials such as hardwood and abrasive woodworking materials. Additionally, it is equipped with a reverse-tooth design for tear-free cuts at the top surface. Its fine tooth pitch (2.5 mm) cuts wooden materials with 3-30 mm thickness. For use with jigsaws with T-Shank clamping systems.
