Milwaukee Bi-Metal Hole Saw, Hole Dozer, 89 mm

Top technology for unparalleled service life. The tooth geometry with variable 4 - 6 TPI Vario-toothing and a positive 10° tooth angle allows for faster and more aggressive cuts, as well as reduced heat generation, which extends the service life of the teeth. Greater tooth depths improve material removal, while specially shaped teeth reduce binding in thin materials. The staggered tooth arrangement decreases friction. Due to the aggressive toothing and good material removal, less feed pressure is required. The tooth material consists of a high-quality HSS alloy with an 8% cobalt content, ensuring excellent service life even in metal. The bi-metal construction with electronically welded HSS teeth on a special steel body ensures optimal cutting quality and long service life. Thanks to the high wear resistance of the HSS alloy, the hole saws are ideal for demanding tasks, such as cutting stainless steel, acid-resistant metals, and softer materials like wood. The hole saw body has a thickness of 1.27 mm and is very stable and self-elastic. The effective cutting depth is 41 mm. The heavy-duty back made of strong steel provides high stability and reduced vibrations. Four pin holes allow for easy locking of the adapter. The precisely manufactured, round back ensures optimal roundness, which is particularly important for hole saws of larger diameters. Unique cutouts facilitate the removal of the drill core. Applications: State-of-the-art production processes ensure precise roundness, allowing the hole saws to be used in both handheld tools and stationary devices. This high-quality range of hole saws is the perfect solution for cutting steel up to 1000 N/mm tensile strength, stainless steel and acid-resistant steel, non-ferrous metals, cast iron, aluminum, wood, MDF boards, drywall, sandwich materials, and plastic.
