The Montolit FPU Diamond Tile Milling Bit is a remarkable innovation in the world of tiling, offering unparalleled precision and versatility in modifying tile and stone. This unique milling bit is specifically designed to enlarge and reshape previously cut holes, making it an indispensable tool for plumbers and electricians who frequently encounter the need to adjust holes for piping, wiring, or other conduits. The FPU bit's capability to refine and clean passages through hard materials like porcelain or granite that a hole saw can't perfectly achieve, marks it as an essential tool for professionals.

What sets the FPU bit apart is its compatibility with standard grinders, sporting a 5/8 inch arbor, making it a highly adaptable tool that can fit into the existing toolkit of any professional. Whether used wet or dry, it maintains its effectiveness, ensuring users can work in various conditions without compromise. Available in sizes like 6 mm (1/4") and 20 mm (3/4"), it caters to a wide range of modification needs. It's important to note that the FPU bit isn’t designed for creating new holes but is specifically crafted for shaping and enlarging existing ones. This distinction underscores its specialized application in professional tiling and stone working projects.
