With the Bahco 3833-51-C Superior multi-construction holesaw, you drill quickly and accurately through diverse building materials. Thanks to precision carbide tips, you cut smoothly through wood, brick, aerated concrete, plasterboard, and plastic without switching tools. With a 51 mm diameter, it produces clean, accurate cutouts for running pipes, conduits, or mounting boxes. The 71 mm cutting depth lets you tackle thick workpieces in a single pass, while deep gullets clear debris rapidly to keep your work moving without interruption. Its internal thread connection allows secure mounting onto a compatible arbor with a pilot drill.
